  1. About

  DKRNL32.DLL is the main part of HX DOS extender's Win32 emulation.
  It will be loaded by PE loader DPMILD32.EXE instead of KERNEL32.DLL.


  2. Requirements

  DKRNL32 expects to find the following environment:

  þ CPU: 80386+, FPU optional. 
  þ DOS: version >= 5. FAT32 and LFN support optional.
  þ DPMI: version 0.9, full API translation for int 21h,
    CS,SS,DS,ES=flat, FS=unused. Version 1.0 optional.
  þ DPMILD32: version >= 3.3, used for dynamic link support, optional.
  þ Keyboard: KB controller 8042 at IRQ 1, direct hardware access
    + keyboard BIOS variable in segment 0040h.
  þ Mouse: int 33h (optional)
  þ Video: VGA (text mode only), direct hardware access
    + video BIOS variable in segment 0040h.
  þ Timer: RTC timer at IRQ 8, direct hardware access
    + PIT timer BIOS variable in segment 0040h (optional).
  þ Serial: DOS device AUX/COMx (optional)
  þ Printer: DOS devices PRN/LPTx (optional)
  þ ASPI: DOS device SCSIMGR$ (optional)

  When DKRNL32.DLL is loaded, it requires about 96 kB memory.


  3. Win32 Emulation Notes

  3.1 Shared File Access

  The Win32 file access API is implemented, of course, but when running
  in plain DOS there may be no SHARE.EXE installed, because AFAIK there
  is none available for versions of MS-DOS supporting FAT32. This may
  cause an application to behave differently if a file is accessed by more
  than one handle (it needn't be a file on a network drive!). For FreeDOS
  there is a SHARE.COM available which works with FAT32, but some versions
  are buggy. Then try http://www.japheth.de/Download/share.zip [FreeDOS only].

  3.2 Time Zones

  To ensure that the time functions work properly you should set
  environment variable TZ. Please note that DKRNL32 currently ignores
  the daylight saving rules.

  3.3 Structured Exception Handling (SEH)

  SEH is supported, but due to some differences between Win32 and DOS
  memory organization there may exist Win32 apps which cannot run in DOS.
  The most remarkable difference is that linear address region 0-FFFFh
  is committed memory in DOS and will not cause a page exception.

  If FPU error conditions cause an exception 10h in the DPMI client, they
  are fully compatible with SEH as implemented by DKRNL32. Regretably most
  servers don't do it that way, instead they report FPU errors by IRQ 13
  (interrupt 75h), even if this interrupt is masked - thus causing the
  machine to hang. HDPMI since version 1.8.7 by default set the NE bit
  in CR0, which is required to generate FPU exception 10h.

  3.4 Long Filenames (LFN)

  DKRNL32 will always try to use the LFN versions of DOS file functions.
  If these calls return with an error indicating LFN is not installed, 
  the older, non-LFN versions are used. 
   When running on NT platforms, the situation is slightly different. Here
  LFN support is installed, but no translation services for protected mode
  applications are implemented. For DKRNL32 versions < 2.8.16 this meant
  that LFN didn't work on NT/2K/XP. Since version 2.8.16 DKRNL32 will 
  install its own translation services in this case (NTLFNHLP) and thus
  LFN works.

  3.5 Threads

  The thread API implementation in DKRNL32 requires the DPMI server to
  preserve the TF flag when switching back from the locked stack. This is
  true for the Windows 9x built-in server, HDPMI and DPMIONE. It doesn't
  work with NT/2K/XP's DOSX, though, but this may be not too relevant
  because the binary usually will run as Win32 app and DKRNL32 isn't
  involved then. For DOSEMU it will possibly work with versions > 1.3.3 only.

  Some thread functions are non-functional, setting the thread priority
  will possibly not make any difference.

  Furthermore, the dispatcher is implemented in ring 3. So if some code
  stores values below current ESP (i.e. at [esp-4]), it may be destroyed
  if threads are switched. 

  3.6 Pipes

  There is some very basic support for anonymous pipes in DKRNL32. 
  CreatePipe will create a file in the temp directory and open 2 handles,
  one with read-only, the other with write-only access to this file. 
  The handles returned by CreatePipe may be used inside the process or
  by CreateProcess to redirect the childs output to the "pipe". Presumably
  this requires shared file access to be installed (see note 3.1). 
   This support is very limited, but since there is currently no support for
  multiple processes in HX, pipes cannot be used as in Win32.

  3.7 File Mapping

  The File Mapping API is implemented, but if it is to be used as
  interprocess communication means it will possibly not work as expected,
  since processes will not run concurrently. Furthermore, if a file is 
  mapped more than once, support for shared file access should be installed
  to make this work as expected (see note 3.1).
  
  3.8 Debugging API

  The Win32 debugging API is implemented as dummies. So Win32 debuggers
  running in console mode (TD32, some versions of GDB) will not run with
  DKRNL32. Since HX supports the Open Watcom full screen debugger WD,
  there are currently no plans to implement this API.

  3.9 Virtual Memory

  The virtual memory API is supported, but the DPMI 0.9 specification 
  doesn't define calls for allocating uncommitted memory or to allocate
  memory at a given linear address. This may result in some Win32 API
  calls to fail or increased committed memory consumption if DKRNL32 is
  running on 0.9 hosts not installing these functions.

  3.10 Devices

  The CreateFile() implementation knows these "devices":

  - "\\.\VWIN32" : Win9x VWIN32 device to access certain DOS interrupts
  - "\\.\APIX"   : Win9x APIX device for ASPI interface access
  - "\\.\PhysicalDriveX": WinNT way to access physical disks
  - "\\.\X:"            : WinNT way to access drives

  The DeviceIoControl() implementation knows these NT control codes:

  -  IOCTL_DISK_GET_DRIVE_GEOMETRY
  -  IOCTL_DISK_GET_DRIVE_GEOMETRY_EX

  if used for physical disks handles.

  The APIX device usually isn't accessed directly, but through WNASPI32.DLL,
  a dll located in the windows system directory. There exist quite some
  versions of this dll and some may not work with HX. The versions included
  in Windows 95b/98 do work, the version from Adaptec is using unknown
  control codes and therefore doesn't work!
  The APIX emulation requires a DOS ASPI driver (ASPI.SYS) to be loaded
  in config.sys, which must install a DOS device named "SCSIMGR$".
  Due to restrictions of the DOS driver model one may get problems burning
  CDs with high speed. In any case there should be no HD cache (SMARTDRV,
  LBACACHE,...) active when burning. OTOH, installing tools like UDMA/XDMA
  should improve things and is recommended.

  3.11 Detecting DKRNL32

  To detect that DKRNL32.DLL is running a program may use Win32 API
  GetVersionExA. DKRNL32 will return 2222 in low word of 
  OSVERSIONINFO.dwBuildNumber - this is the same as Windows 98 SE - and 
  OSVERSIONINFO.szCSDVersion[0] will be 0.
  Since version 2.8.28 one can detect DKRNL32 by calling GetProcAddress
  with string "GetDKrnl32Version". If this call returns with EAX != 0,
  DKRNL32 is installed, and calling this address will return the current
  DKRNL32 version, the major version no in AL, the minor version no in AH 
  and any subminor version no in HIWORD(EAX).


  4. Environment Variables known by DKRNL32

  4.1 Variable DKRNL32

  When initializing DKRNL32.DLL will read environment variable DKRNL32.
  The value must be a number (for example, DKRNL32=1), which consists of
  individual bits (or flags). The following flags are currently known:

  0001: 1=DKRNL32 remains active when a new process is starting. If set 
        to 0 (the default), DKRNL32 disables its IRQ handlers just before
        a new process is launched and reenables them when the process has
        finished. This avoids possible conflicts, but may be unwanted if
        the launching Win32 application shall provide services for the
        new process (kind of a "Win32 TSR") or must stay active for other
        reasons.
  0002: 1=DKRNL32 does not hook exceptions 1 and 3. This might be useful
        if the application is to run under a debugger.
  0004: 1=threads will get full default stack size. 0=threads get a
        default stack size of 96 kB.
  0008: not used.
  0016: 1=DKRNL32 will always use the RTC for GetTickCount, the PIT timer
        isn't used at all then.
  0032: 1=DKRNL32 will hook no exceptions (for debugging).

  4.2 Variable TZ

  With this variable the time zone is set.

  4.3 Variables DKRNLLOG and DKRNLDBG

  DKRNLLOG is only useful if a debug version of a Win32 dll must
  be tested. It will redirect debug output of this dll to the file defined
  with this variable, for example:

  SET DKRNLLOG=C:\TEMP\DKRNL32.LOG

  DKRNLDBG are various flags for fine-tuning debug output. It is useful
  only if a debug version of DKRNL32 itself is tested.


  5. Function List

  The following functions are currently exported by DKRNL32.DLL. The
  behaviour is not always exactly identical compared with their Win32
  conterparts. Some procs are just dummies. For more details you will
  need HXSRC package, which contains the full MASM source code.

  6. History

  05/27/2011: version 3.5

  þ bugfix: DuplicateHandle() didn't work for mutexes and waitable timers.
  þ bugfix: the kernel heap was defined incorrectly, which raised the risk
    that part of its content was corrupted if an application created lots
    of kernel objects.
  þ bugfix: low-level disk write access (LBA) was often rejected because
    invalid flags may have been set for int 13h, ah=43h.
  þ GlobalAddAtomW() added.
  þ GetNumberFormatW() added (stub).
  þ GetCurrencyFormatA() + GetCurrencyFormatW() added (stubs).
  þ OpenWaitableTimerA() added.
  þ heaps are now serialized with a mutex instead of a semaphore.
  þ the default exception handler will display contents of CS:EIP and SS:ESP.
  þ SetEvent() will switch threads if a thread is waiting for the event.
  þ mouse wheel events supported
  þ save/restore FS register when another program is launched. This is needed
    when DPMILD32 is to run another Win32 application in the same client.
  þ bugfix: WaitForSingleObject/WaitForMultipleObjects didn't set last error
    when returning WAIT_FAILED.

  11/16/2009: version 3.4

  þ bugfix: GetFileType() didn't set last error, thus making return value
    of FILE_TYPE_UNKNOWN ambiguous.
  þ bugfix: virtual key codes were wrong for numpad-0 - numpad-9 if
    NUMLOCK was on.
  þ bugfix: GetDateFormat() and GetTimeFormat() caused buffer overflows.
  þ bugfix: SetCurrentDirectory() sometimes didn't work.
  þ bugfix: FormatMessage() max line length handling was wrong.
  þ bugfix: ack from kbd (0FAh) during LED update wasn't ignored.
  þ bugfix: WritePrivateProfileString() failed if file didn't exist yet.
  þ bugfix: GetPrivateProfileSectionNames() returned size 1 too high.
  þ bugfix: adding a new key with WritePrivateProfileString() did delete
    all following sections.
  þ bugfix: Peek-/ReadConsoleInput(): pressed right ALT key has to set
    status RIGHT_ALT_PRESSED *and* LEFT_CTRL_PRESSED for 100% Windows 
    compatibility. The latter wasn't implemented.
  þ bugfix: GetPrivateProfileSectionA() skipped lines which didn't follow
    the <key>=<value> format.
  þ GetBinaryTypeW added.
  þ GetVDMCurrentDirectories, CmdBatNotification added (dummies).
  þ support for LOCALE_SSHORTDATE implemented.

    valid.
  þ GetThreadSelectorEntry() implemented.
  þ IsProcessorFeaturePresent() activated.
  þ SetFilePointer(), parameter 'origin': validity check added.

  þ EncodePointer, DecodePointer added (stubs)
  þ RtlUnWind: made compatible with SEH of Borland C++.
  þ GetSystemWindowsDirectoryA/W added.

  01/20/2009: version 3.3

  þ source assembled with JWasm.
  þ bugfix: thread idle detection code might have caused a GPF.
  þ bugfix: exception handler destroyed content of application's EFlags
    register.
  þ bugfix: physical disk access didn't work with non-LBA HDs.
  þ bugfix: source of v3.2 gave assembly errors, STARTUPINFO changed to
    STARTUPINFOA.
  þ DeviceIoControl: support for IOCTL_STORAGE_CHECK_VERIFY

  03/02/2008: version 3.2

  þ bugfix: IOCTL_DISK_GET_DRIVE_GEOMETRY_EX didn't return the drive
    parameters due to an alignment error.
  þ bugfix: dkrnl's exception handler destroyed content of EAX.
  þ bugfix: the CreateThread's "stack size" parameter was interpreted
    as full size of stack, but it is meant as committed size only.
  þ stack guard page implemented if DKRNL32 runs on HDPMI, which may
    reduce the memory footprint of threads significantly.
  þ value at FS:[8] now holds the committed stack bottom as in Win32.
  þ committing a previously reserved large memory block does not longer
    require + use large stack space.
  þ bugfix: SearchPath() no longer fails if a full path is given as filename.
  þ another PIT timer fix. Now the timer counter is just read again if a
    wrap occured during the read.
  þ exception 11h is caught and translated to EXCEPTION_DATATYPE_MISALIGNMENT.
  þ bugfix: FormatMessageA() interpreted the nSize parameter wrong if a buffer
    is to be allocated.
  þ bugfix: FormatMessageW() did allocate the buffer in bytes, not words.
  þ bugfix: DKRNL32 initialization disabled a possibly installed FPU emulator.
  þ DKRNL32 will call the DPMILD32 API only if DPMILD32 is present.
  þ switch DKRNL32=32 added.
  þ bugfix: GetDiskFreeSpace/GetDiskFreeSpaceEx was restricted to 2 GB in
    MS-DOS (not in FreeDOS).
  þ bugfix: GetLocaleInfo returned codepages in hexadecimal (ie. 352 instead
    of 850).
  þ GetLocaleInfo: added support for 
    - LOCALE_ICOUNTRY
    - LOCALE_STHOUSAND, LOCALE_SDECIMAL,
    - LOCALE_SCURRENCY, LOCALE_ICURRENCY, LOCALE_ICURRDIGITS,

  þ CancelIo, GetOverlappedResult implemented.
  þ bugfix: GetDiskFreeSpaceW didn't expect NULL as first parameter
  þ GetDiskFreeSpaceExW added.
  þ Ctrl-Break signal handling is now always done by a separate thread.
    If there is no thread when int 23h is called, it is created on the fly.
  þ bugfix: BREAK was set to off and not restored on exit.
  þ new DKRNL32 environment switch 0008 will cause DKRNL32 to disable the
    keyboard before reading port 60h. This might make the keyboard work better
    in virtual machines which don't emulated this device correctly (Qemu).
  þ bugfix: 2 dwords should be reserved at the stack top, but this wasn't
    true in v3.0.0 after ExitProcess has been called. Problem: Delphi 
    generates an exception 0eh.
  þ better protection of text screen resolution changes against buggy BIOSes.
  þ bugfix [OMF dkrnl32s.lib only]: InitStaticTLSthread was not deactive.
  þ bugfix [OMF dkrnl32s.lib only]: GPF on init when clearing TIB.
  þ bugfix [OMF dkrnl32s.lib only]: GPF in Ctrl-Break handler.

  þ UTF-16 "box drawing" support implemented for WriteConsoleOutputW()
  þ bugfix: GetFileInformationByHandle, file times weren't set to zero
    if times not available.
  þ OpenProcess, TerminateProcess will now work with current process.
  þ bugfix: Process32First didn't return filename and process id was wrong.

  þ GetPrivateProfileStringW, WritePrivateProfileStringW added
  þ GetStringTypeExW added
  þ OpenEventW added
  þ EnumSystemLocalesW added (dummy)
  þ SwitchToThread added
  þ bugfix: CreateFile didn't set last error if CREATE_ALWAYS or OPEN_ALWAYS
    was set and function succeeded (ZERO or ERROR_ALREADY_EXISTS).
  þ DeviceIoControl now understands IOCTL_DISK_GET_DRIVE_GEOMETRY and
    IOCTL_DISK_GET_DRIVE_GEOMETRY_EX.
  þ low-level disk access with \\.\PhysicalDriveN and \\.\X: implemented.
  þ bugfix: SetFilePointer: offsets >= 100000000h will return an error now.
    Previously the higher 32bits were just ignored.
  þ the kernel heap can grow now and its default size is smaller.
  þ timer used for thread switching is now created and deleted just once.
  þ bugfix: ResumeThread() might have caused all but one thread to be
    inactive.
  þ CreateDirectoryExW added
  þ option DKRNL32=16 added to allow to avoid using the PIT timer.
  þ if the PIT timer is used - which is standard when running in true DOS -
    it's no longer assumed that counter mode 3 is set. 
  þ GetSystemTimeAdjustment now implemented
  þ SystemTimeToTzSpecificLocalTime added

  07/15/2007: version 3.0

  þ function GetSystemDefaultUILanguage was missing.
  þ GetSystemDefaultUILanguage/GetUserDefaultUILanguage now return the
    same value as GetSystemDefaultLangID/GetUserDefaultLangID.
  þ bugfix: GetFullPathNameW has caused a GPF if lpFilePart param was NULL.
  þ TIB now handled entirely by DKRNL32. Furthermore, each thread gets
    its own TIB (previously there was just one and values were copied on
    thread switches) and its own selector for FS.
  þ RequestWakeupLatency added (dummy).
  þ GlobalHandle and LocalHandle now call HeapValidate() for the handle.
    Previously they didn't check if the handle was valid.
  þ ReadConsoleOutputW, ReadConsoleOutputCharacterW added.
  þ WritePrivateProfileSectionA added.
  þ GetComputerNameW added.
  þ implementation of toolhelp functions improved.
  þ bugfix: ReadConsole implementation changed. It no longer uses int 16h,
    but ReadConsoleInput.
  þ bugfix: GetVolumeInformation with lpFileSystemNameBuffer parameter == NULL
    caused a GPF.
  þ SetProcessShutdownParameters added (dummy). 
  þ GetWindowsDirectory now returns directory where DKRNL32 has been loaded
    from. Previously it returned fix "C:\", but some applications don't expect
    this string to end with a backslash.
  þ mouse wheel support prepared.
  þ last error now stored in TIB (Win9x compatible).
  þ bugfix: GetProcessVersion didn't work and often caused a GPF.
  þ bugfix: static TLS was handled for the main thread only.
  þ ReadFile changed so that if it reads from std input it doesn't has to
    wait in DOS.
  þ _hread, _hwrite added (synonyms for _lread, _lwrite).
  þ GetFileInformationByHandle now uses the SFT to get file attributes
    if int 21h, ax=71A6h failed (which fails even if DOSLFN is loaded!).

  03/15/2007: version 2.9.13

  þ bugfix: CreateProcess didn't set last error.
  þ bugfix: SetFilePointerEx returned -1 for failure, and if parameter 3
    was NULL it caused a GPF.
  þ bugfix: FlushConsoleInputBuffer may have caused a lock.
  þ bugfix: ReadConsoleInput with a buffer > 1 returned only after
    buffer has been filled, not just after at least 1 event has been read.
  þ to determine the end of process initialization, int 41h is hooked.
    Previously DKRNL32 relied on a flag set by DPMILD32 in the image's
    MZ header.
  þ DKRNL32 does no longer use image's MZ header to store the PROCESS object.
  þ ExitProcess switches to application stack before running int 21h, ah=4Ch.
  þ resource id names starting with '#' now supported.
  þ ReadConsoleInputW implemented, PeekConsoleInputW and WriteConsoleInputW
    added.
  þ IsBadStringPtrW added, IsBadCodePtr implemented.
  þ int 21h is hooked to catch ah=4Ch. This improves stability on exit if
    the call is done from outside of DKRNL32.
  þ LocalHandle added (dummy)
  þ ReadFile/WriteFile now handle an "Overlapped" parameter <> NULL.
  þ GetSystemDirectory now returns directory where DKRNL32 has been loaded
    from, not the current directory.
  þ GlobalGetAtomNameW added.
  þ DKRNL32 uses new DPMILD32 API int 21h, ax=4b95h to set a "system 
    directory" (which is searched when loading dlls just before the PATH
    is scanned).  

  12/14/2006: version 2.9.12

  þ bugfix: calling ReadFile/WriteFile with a handle of -1 caused a GPF.
  þ bugfix: if huge amounts of memory where allocated and application stack
    was relatively small, there could have been a stack overflow inside
    VirtualAlloc if a thread switch occured.
  þ CreateMailslotA, GetMailslotInfo, SetMailslotInfo added (dummies)
  þ some values returned by GetSystemInfo adjusted:
     dwAllocationGranularity     now 0x10000, prev. 0x1000
     lpMinimumApplicationAddress now 0x110000, prev. 0x10000
     lpMaximumApplicationAddress now 0xFEFFFFFF, prev. 0xFFFFFFFF
     wProcessorLevel             now cpu 3/4/5, prev. 0
  þ bugfix: some functions which expect a process handle as parameter
    failed because the handle was regarded as invalid.
  þ CreateSemaphoreW added
  þ GetDateFormatW, GetTimeFormatW added
  þ GetFileSizeEx, GetDiskFreeSpaceW, SetFilePointerEx added
  þ new value 2 for DKRNL32 environment variable

  10/15/2006: version 2.9.11

  þ bugfix: FillConsoleOutputAttribute/FillConsoleOutCharacterA caused
    a crash if length parameter was zero.
  þ bugfix: space used by items released by HeapFree was not recovered
    in all cases.
  þ bugfix: in HeapRealloc, if item size growed and was able to grow
    in place, it may have corrupted heap. 
  þ bugfix: GlobalFree/LocalFree returned eax == 1 on success and
    NULL on failure.
  þ bugfix: calling ReadFile() with an anonymous pipe handle will now wait
    if pipe is empty (might require SHARE to be loaded!).
  þ SetThreadPriority with a value THREAD_PRIORITY_TIME_CRITICAL *2 
    will prevent thread switches. This is a hack for HXGUIHLP when it
    is showing it's menu (and will most likely be changed).
  þ FillConsoleOutputCharacterW, ScrollConsoleScreenBufferW added
  þ GetVolumeInformationW added
  þ GetPrivateProfileSectionA added
  þ Environment variable DKRNL32 implemented. Value 1 is valid.

  09/14/2006: version 2.9.10

  þ WriteConsoleOutputW, WriteConsoleOutputCharacterW added

  08/15/2006: version 2.9.9

  þ GetPrivateProfileSectionNamesA added
  þ console signals (Ctrl-Break,...) now handled in a separate thread
    as it is done in Win32.
  þ GetNamedPipeInfo, DisconnectNamedPipe added (dummies)
  þ SetProcessAffinityMask added (dummy)
  þ bugfix: non-flat code (used for HX MZ binaries only) screen output
    didn't work in last version.
  þ bugfix: previous version's WriteConsole() didn't work with non
    black-white default screen attribute or if screen was in graphics mode.
  þ bugfix: setting attributes for directories didn't work.
  þ bugfix: WriteConsoleOutput()/ReadConsoleOutput() used current screen
    size variables, not the values of current screen buffer.
  þ bugfix: some additional security checks added to WriteConsoleOutput().
  þ bugfix: GetFileType() may have returned file type "device" if the file
    was indeed "remote".

  07/15/2006: version 2.9.8

  þ bugfix: GetTempPath didn't return the current directory if both TMP and
    TEMP environment variables weren't defined.
  þ bugfix: if flags ENABLE_LINE_INPUT and/or ENABLE_ECHO_INPUT were reset,
    ReadConsole didn't work as expected.
  þ bugfix: TlsGetValue, TlsSetValue didn't set last error.
  þ bugfix: TlsFree didn't set last error. And value wasn't reset to 0
    for current thread.
  þ console text attributes are no longer global and work with WriteConsole
  þ AttachConsole added (works with parameter ATTACH_PARENT_CONSOLE only)
  þ debug output via OutputDebugString() or Int 41h now written to a file
    in release version if environment variable DKRNLLOG is set.
  þ thread code splitted which makes MZ binaries smaller if no threads are
    used/created.

  06/14/2006: version 2.9.7

  þ bugfix: WriteConsole didn't work with console screen buffer handles.
  þ bugfix: GetConsoleScreenBufferInfo and SetConsoleScreenBufferSize didn't
    work with inactive screen buffers.
  þ bugfix: PeekConsoleInput was unable to peek anything but the first event
    in the queue.
  þ bugfix: OpenFile was unable to create a nonexisting file.
  þ bugfix: GetPrivateProfileStringA with parameter lpAppName or lpKeyName
    == NULL didn't return the bytes copied to the return buffer.
  þ bugfix: if type or name parameters in FindResource were strings, the
    search was done case-sensitively.
  þ bugfix: MoveFile didn't work if old file and new file were on
    different volumes. 
  þ MoveFileEx implemented
  þ GetCurrentDirectoryW, GetDriveTypeW, ExpandEnvironmentStringsW,
    SetEnvironmentVariableW, CreateProcessW, GetTempFileNameW, SearchPathW,
    OpenFileMappingW, GetTempPathW, CopyFileW, MoveFileExW implemented
  þ if running in a WinXP DOS box call int 16h, ah=01 to indicate idle state
    (int 2Fh, ax=1680h doesn't work in this environment)

  05/15/2006: version 2.9.6

  þ bugfix: GetVolumeInformationA on some conditions returned 0 although
    the given path was valid.    
  þ bugfix: GetLogicalDrives didn't return network or cd-rom drives.
  þ ConnectNamedPipe added (dummy)
  þ CommConfigDialogA, SetupComm, GetDefaultCommConfigA added (dummies)
  þ GetSystemTimeAdjustment added (dummy)
  þ InterlockedExchangeAdd added
  þ GetProcessVersion added
  þ refuse to write-protect PE header of current application. The header
    is used by DKRNL32 to store some important infos (UPX v2).
  þ FormatMessageA emulation improved.

  05/02/2006: version 2.9.5

  þ flush console input buffer if ReadFile has read the current console
    and buffer input is active.

  04/21/2006: version 2.9.4

  þ GetProcessWorkingSetSize, SetProcessWorkingSetSize,
    GetProcessAffinityMask, GetProcessTimes now accept a hard-coded
    process pseudo handle (-1).

  03/21/2006: version 2.9.3

  þ DeleteFileA, MoveFileA, CreateDirectoryA, RemoveDirectoryA: save/restore 
    EBX to make these functions compatible with FreeDos + MS-DOS < 7.

  03/18/2006: version 2.9.2

  þ GetNumberFormatA added
  þ GetEnvironmentVariableW, GetSystemDirectoryW, GetBinaryTypeA added
  þ a hack implemented to ensure that the thread dispatcher is deactive
    during DLL_PROCESS_ATTACH.. DPMILD32 will then enable the dispatcher
    just before it jumps to the app's initial entry .
  þ GlobalCompact added (dummy)
  þ CreateProcess: if bInheritHandles parameter is false, file handle table
    is reset to default values so redirected handles will not be used by
    the child.
  þ GetPrivateProfileStringA/WritePrivateProfileString now cache the 
    last accessed file.
  þ now DKRNL32 frees all memory blocks when being unloaded. This is
    usually done by the dpmi host, but only if the client terminates, which
    may not be true in all cases.
  þ DKRNL32 tried to detect the idle state when multiple threads were running
    and gave up the time slice then (calling int 2Fh, ax=1680h). This
    apparently caused problems on FreeDOS and Win9x DOS boxes.
  þ bugfix: WaitForSingleObject/WaitForMultipleObjects didn't know
    process handles.
  þ bugfix: ExpandEnvironmentStringsA was documented as implemented, but
    in fact just copied the source string. Now implemented.
  þ bugfix: SetStdHandle didn't accept a console screen buffer handle.
  þ bugfix: SetConsoleCursorPosition, SetConsoleCursorInfo and 
    GetConsoleCursorInfo now check if the handle is the active screen
    buffer. If not, the physical cursor is untouched.
  þ bugfix: code which notified dll entries about thread start/termination
    didn't test if dll entry point is NULL.
  þ better support for LCIDs in GetUserDefaultLCID + GetSystemDefaultLCID.
  þ CreateSocketHandle added. This is an undocumented KERNEL32 function, but
    needed, because it allows CloseHandle/DuplicateHandle to accept socket
    handles. Used by WSOCK32.DLL.
  þ bugfix: calling GetPrivateProfileStringA with parameter lpAppName==NULL 
    destroyed content of EBX register. 
  þ GetFullPathNameA: save/restore EBX to make this function compatible
    with FreeDos + MS-DOS < 7.
  þ bugfix: SetStdHandle directly modified the file handle table, which
    confused DOS. Now it uses standard DOS calls only.
  þ bugfix: calling WaitForMultipleObjects with a file handle may have
    caused a GPF.
  þ IsBadReadPtr, IsBadWritePtr, IsBadStringPtrA implemented.
  þ CreateDirectoryExA added
  þ MoveFileExA added (dummy)
  þ FindFirstChangeNotificationA, FindNextChangeNotification, 
    FindCloseChangeNotification added (dummies)
  þ CreateNamedPipeA, SetNamedPipeHandleState, WaitNamedPipeA added (dummies)
  þ CreateTapePartition, EraseTape, GetTapeParameters, GetTapePosition,
    GetTapeStatus, PrepareTape, SetTapeParameters, SetTapePosition, 
    WriteTapemark added (dummies)
  þ GetProcessTimes, GetThreadTimes, SetThreadAffinityMask added (dummies)
  þ SetCommBreak, ClearCommBreak, ClearCommError, GetCommModemStatus,
    GetCommState, SetCommState, GetCommMask, SetCommMask, PurgeComm,
    WaitCommEvent, TransmitCommChar, SetCommTimeouts, EscapeCommFunction
    added (dummies).
  þ bugfix: console screen buffer handling didn't work with Turbo Vision.
  þ waitable timers now really count down in ms, previously they count down
    in RTC timer ticks (which last 0.977 ms).
  þ some places which temporarily disable interrupts modified in a way 
    so they now use the DPMI virtual interrupt functions. This is required
    by WinXP and DosEmu, where the IF doesn't tell the state of the VIF.
  þ bugfix: int 21h, ah=1Ah (set DTA, used by findfirst/findnext if LFN is 
    not installed) was not thread-safe.
  þ bugfix: there was a slight chance that the dispatcher called CloseHandle
    while the kernel heap was locked, causing a deadlock.
  þ bugfix: exception handler expected DS to be zero-based flat.
  þ bugfix: thread context saving in version 2.9.1 always did a FNINIT,
    which should only be done on float exceptions.
  þ moved the code which divides large blocks of data to be read/write
    into smaller chunks into the thread dispatcher int 21h hooker, where
    it belongs.

  02/06/2006: version 2.9.1

  þ bugfix: save/restore current directory if CreateProcess is called.
  þ dispatcher changed to use the RTC timer. So now a time slice is 20 ms,
    previously it was 55 ms.
  þ default exception handler now displays module name + offset of
    exception address.
  þ GetThreadContext/SetThreadContext implemented
  þ bugfix: WaitForSingleObject/WaitForMultipleObjects now don't wait at
    least 55 ms if the wait parameter is smaller.
  þ GetTickCount resolution improved (previously was 55 ms, now 1 ms)
  þ PulseEvent no longer dummy
  þ DOS LFN API translation now activated if host is DPMIONE (which
    has no such services implemented)
  þ bugfix: the RTC timer may have been deactivated when another
    program has been launched.

  01/22/2006: version 2.9

  þ use PIC mappings reported by DPMI host for keyboard and timer hooks.
  þ bugfix: GetTempPathA did not append a '\' if it was missing.
  þ bugfix: virtual key VK_OEM_MINUS not recognised
  þ key event hookers may now set the carry flag to cause
    dkrnl32 standard processing. This is an issue with the
    DirectInput emulation, which previously swallowed all
    key presses even if in non-exclusive mode.
  þ if all threads are blocked, the dispatcher will now 
    release the time slice. Previously this only worked for
    single-threaded apps.
  þ bugfix: if values read with GetPrivateProfileString were 
    enclosed in quotation marks, these marks weren't skipped.
  þ Size of stack for new threads which don't specify the stack
    size now is 96 kB (previously it was 64 kB). The first 4 kB
    are still uncommitted. This avoids problems with OW's stack
    checking routine. And value at FS:[8] is now set for each
    thread accordingly.
  þ bugfix: usage of stack space for VirtualAlloc, VirtualFree,
    VirtualProtect and VirtualQuery was restricted to max 2 kB
    (bugfix of 2005.08.11), but this made it impossible to 
    return to the previous state if an error occured during the
    operation. So now stack usage is limited to available stack
    space.
  þ GetProfileStringA added (dummy)
  þ GlobalAddAtomA, GlobalDeleteAtom, GlobalFindAtomA, 
  þ GlobalGetAtomNameA added (code for these functions is the same
    as for the local [without "Global" prefix] ones)
  þ bugfix: GetCurrentThreadId may have returned 0 as thread id
  þ bugfix: calling ExitThread for the main thread didn't work

  01/02/2006: version 2.8.36

  þ DbgPrint, GetVersionExW added
  þ bugfix: thread exit code lost in version 2.8.34-2.8.35
  þ GetProcessAffinityMask, VirtualProtectEx added
  þ GetPrivateProfileString/WritePrivateProfileString no longer
    have a 64 kB limitation
  þ bugfix: WritePrivateProfileString did not reduce file size
    if necessary. And replacing the value of an existing key
    may have produced garbage in the following line.
  þ LoadModule added
  þ GetVolumeInformationA now returns volume label for CDROMS
    (at least if DOSLFN+SHSUCDX is installed)

  12/20/2005: version 2.8.35

  þ now DKRNL32 should be compatible with MS mouse drivers when
    a VESA graphics modes is active.
  þ bugfix: when running on hosts which don't support setting  
    page attributes, VirtualAlloc may not have zeroed the memory.
  þ GetPriorityClass added 
  þ IsProcessorFeaturePresent implemented (deactivated)

  12/07/2005: version 2.8.34

  þ bugfix: GetDriveTypeA now can detect RamDisk + CDROM drives
  þ bugfix: GetVolumeInformationA modified register ESI

  þ lstrcpyW added
  þ MakeCriticalSectionGlobal added (dummy)

  11/24/2005: version 2.8.33

  þ lstrcatW added
  þ added 49 dummy exports without names (ordinals 1 to 49) to
    avoid problems with applications using undocumented exports. 
  þ BackupWrite added (dummy)
  þ GetLogicalDriveStringsA added
  þ Sleep() now uses a cached timer if interval to sleep is < 110 ms

  11/18/2005: version 2.8.32

  þ MulDiv added
  þ bugfix: Ctrl-Break/Ctrl-C signals no longer allow thread
    context switches.
  þ bugfix: thread stack wasn't freed in any case
  þ bugfix: Sleep() with a parameter of < 55 ms didn't wait at
    all if more than one thread was running.
  þ bugfix: SetEndOfFile() didn't set last error code
  þ bugfix: GetFullPathNameA didn't expect NULL as lpFilePart
    parameter
  þ bugfix: APIX device may have used DOS (to free memory) when
    it was already in use.
  þ bugfix: WaitForSingleObject/WaitForMultipleObjects didn't wait
    the specified amount of milliseconds if more than one thread
    was running.

  11/07/2005: version 2.8.31

  þ Support for device APIX added
  þ QueryDosDeviceA, GetProcessWorkingSetSize, GetOverlappedResult
    added (dummies)
  þ exception 0C now caught (useful if DPMILDR=2048 is set)
  þ default exception handler now writes to stderr, not stdout
  þ setting/getting keyboard/mouse event handler simplified
  þ bugfix: the lowest 4k of a thread's stack was allocated 
    as uncommitted memory in any case, regardless if a stack
    size was given or not.
  þ save/restore console mode when launching another process
    (to reenable mouse input)
  þ bugfix: extended keys may have caused function ToAscii() 
    return ascii code 0E0h.
  þ bugfix: DKRNL32 exception handler still handled exception
    if DKRNL32 was disabled.

  10/24/2005: version 2.8.30

  þ Virtual keys VK_LWIN, VK_RWIN and VK_APPS supported
    in PeekConsoleInput/ReadConsoleInput.
  þ PAUSE key event handling improved. For GUI apps, real-mode
    keyboard driver is NOT called for this key.
  þ Size of stack for new threads which don't specify the stack
    size now is 64 kB (previously it was 16 kB). The first 4 kB
    may be uncommitted memory (if dpmi host supports this).
  þ full support for key up events implemented.
  þ mouse event queue implemented (previously just the last event
    was saved)
  þ CancelIo added (dummy)
  þ CreateWaitableTimerA, SetWaitableTimer, CancelWaitableTimer
    implemented
    QueueUserAPC added (dummy)
  þ HeapValidate now catches exceptions
  þ bugfix: Mutexes didn't work as expected.

  09/28/2005: version 2.8.29

  þ added export Borland32. This will cause powerpack apps to
    realize that they are running in DOS, not Win32. 
  þ Ctrl+Break now signaled asynchronously if running under HDPMI
    and indos flag is zero. This is restricted to HDPMI because
    many hosts don't like the client to terminate while on the
    locked stack.
  þ QueryPerformanceFrequency no longer dummy
  þ QueryPerformanceTimer now reads timer 0 counter + BIOS variable

  09/19/2005: version 2.8.28

  þ bugfix: SetCurrentDirectory() didn't work in plain DOS if
    last character was a '\' ("X:\" worked, however)
  þ GetDKrnl32Version function added.
  þ for .model SMALL only: process heap initialization is now done
    before any initializers were called in the kernel. Previously
    it was done in the CRT startup module. As well some bugfixes
    for this model added concerning virtual memory allocation.
  þ HeapCreate: parameter 'initial size' now used. Previously there
    was always at least 1 MB committed memory allocated. Now most of
    the heap space initially is allocated as uncommitted memory - if
    the DPMI host supports this feature. This should reduce memory
    load, which may be significant on machines with less than 32 MB
    of memory.
  þ reserved heap area now rounded up to a 64 kB boundary. 
  þ bugfix: VirtualAlloc with a base != 0 and MEM_RESERVE did
    round down the base to a 64 kB boundary, but requested size
    wasn't adjusted accordingly, so VirtualAlloc(8001000h,1000h)
    returned a region starting at 8000000h with size 1000h, but
    size should have been 2000h.
  þ GetConsoleTitleW, SetConsoleTitleW added (dummy)
  þ lstrcmpW added

  09/06/2005: version 2.8.27

  þ FlushViewOfFile now really writes modifications back to file.
  þ CreateMutexW, InterlockedCompareExchange, GetModuleHandleW,
    CreateEventW, GetFileAttributesExW, lstrcmpiW added
  þ bugfix: CreateFileMapping with a name parameter checked 
    existance of this object, but didn't check the type.
    Now if type doesn't match, last error = 6 is set.

  08/28/2005: version 2.8.26

  þ DOS extended break checking turned off on initialization

  08/14/2005: version 2.8.25

  þ HeapCreate, HeapAlloc, HeapFree and HeapReAlloc: support for 
    flag HEAP_NO_SERIALIZE added. HeapCreate, HeapAlloc and
    HeapReAlloc: support for flag HEAP_GENERATE_EXCEPTIONS added.
  þ bugfix: VirtualAlloc, VirtualFree, VirtualProtect and
    VirtualQuery may have used a large amount of stack space if
    memory region to commit/uncommit/protect/query was big
    (64 kB of stack space for a 128 MB memory region). This may
    have caused a stack overflow. Now stack usage is limited
    to 2 kB.
  þ VirtualFree now supports decommitting pages on a 1.0 host
  þ bugfix: VirtualFree didn't fail if dwFreeType was 0
  þ bugfix: if allocating large items with HeapAlloc caused the
    heap to grow, the growing strategy didn't take into account
    the size of a possibly free item at the end of the heap.
    This may have caused inefficient memory usage.
  þ bugfix:calling WaitForSingleObject with a file handle 
    (!= stdin) didn't work

  08/06/2005: version 2.8.24

  þ debugger exception notification changed to int 41h, ax=7Fh
    (check if debugger wants fault notification) and int 41h,
    ax=83h (notify debugger of fault). previously was just a
    GO TO (ax=F003h).

  08/01/2005: version 2.8.23

  þ bugfix: forgot to adjust SetFileTime :((

  08/01/2005: version 2.8.22

  þ bugfix: there was still an error in local time zone handling
    which caused functions GetFileTime, GetFileAttributesEx,
    FindFirstFile/FindNextFile and GetFileInformationByHandle
    to return wrong times :(.
  þ previous versions of GetStartupInfo cleared all fields
    of STARTUPINFO parameter. Now some fields are set only
    (some apps don't supply a full STARTUPINFO structure!)
  þ NtCurrentTeb added. Required by MS C v8.0 16-bit compiler.
  þ RtlExAllocateHeap, RtlExFreeHeap and RtlExReAllocateHeap   
    added, which call HeapAlloc, HeapFree, HeapReAlloc.
    Required by MS C v8.0 16-bit compiler (DOSXNT).
  þ FormatMessage now knows how to scan message table resources
    and will handle message insert arguments.
  þ int 23h handler will only switch stacks if current stack
    is the locked protected-mode stack.
  þ bugfix: VirtualQuery now knows memory block used for images
  þ bugfix: in VirtualQuery some fields were not set in all cases.
  þ save/restore esp when calling Ctrl-C handler procs.
  þ bugfix: in default console attributes flags ENABLE_LINE_INPUT
    and ENABLE_ECHO_INPUT were not set.

  07/20/2005: version 2.8.21

  þ bugfix: FileTimeToDosDateTime/DosDateTimeToFileTime no longer
    make conversions to/from local time
  þ environment variable TZ will now be read early in DKRNL32
    initialization. Previously it was read when the first
    time zone related function was called, but some apps 
    (InfoZip's Unzip.exe) delete TZ as one of their first tasks?!
  þ bugfix: GetTimeZoneInformation now returns Bias and name
    of time zone if environment variable TZ is set
  þ RtlGetNtVersionNumbers added so MSVCRT.DLL of WinXP
    will load successfully
  þ GetSystemDirectoryA, WaitForMultipleObjectsEx,
    FreeLibraryAndExitThread, SleepEx added
  þ bugfix: if the target region of ScrollConsoleScreenBufferA 
    was outside of the screen dimensions, it wasn't clipped. 
  þ bugfix: CreateFileMappingA returned an error if named
    mapping object already existed. 
  þ CreateSemaphoreA now accepts a name parameter != NULL
  þ OpenSemaphoreA added

  07/14/2005: version 2.8.20

  þ application will be notified now of EXCEPTION_INT_OVERFLOW
    (exc 04) and EXCEPTION_ARRAY_BOUNDS_EXCEEDED (exc 05)
  þ bugfix: exception translation was deactivated, so the 
    application got exception code 0Eh instead of C0000005h

  07/13/2005: version 2.8.19

  þ bugfix: GetEnvironmentVariable didn't expect nSize parameter
    to be 0.
  þ dkrnl32's internal heap size has been enlarged from 32768
    to 49152 bytes. Since the kernel heap objects are very small,
    this should be more than enough, but apparently there exist
    apps which require this size.
  þ bugfix: WinExec used CreateProcess, but didn't close the
    hProcess and hThread handles returned in PROCESS_INFORMATION
  þ bugfix: CreateProcess didn't return a valid handle for
    hThread in PROCESS_INFORMATION
  þ CreateProcess now checks for std handles to be inherited in
    STARTUPINFO parameter. 
  þ PeekNamedPipe no longer dummy
  þ CreatePipe no longer dummy (but only limited usability)
  þ bugfix: open a file with read access and share-mode write, then
    open it with write access and share-mode read failed.
  þ bugfix: GetTempFileName did use only 2 bytes from prefix string
  þ bugfix: closing a thread's handle shouldn't release the
    memory until the thread is terminated.
  þ bugfix: GetCommandLine didn't add a trailing space to the
    program path if the "real" command line was "empty"
  þ bugfix: MapViewOfFile returned 0 on further calls with the same
    offset and just desired access changed.
  þ OpenFileMappingA no longer dummy
  þ dkrnl32's exception handler now checks if current Esp can
    be used. If no, a small helper stack is used. This should
    catch stack overflows, which in previous versions caused a
    infinite loop.

  07/06/2005: version 2.8.18

  þ bugfix: PeekConsoleInputA returned eax=0 if nothing was read
  þ bugfix: ReadFile on console handle now checks for
    ENABLE_LINE_INPUT and ENABLE_ECHO_INPUT
  þ flush the dos input buffer on FlushConsoleInputBuffer
  þ GenerateConsoleCtrlEvent added 
  þ FlushInstructionCache dummy added 
  þ GetProcAddress info: dpmild32 now supports ordinal numbers
    for its int 21h, ax=4b81h API. Since this API is used by 
    dkrnl32's GetProcAddress, this function now supports ordinals
    as well. Required by the delay loading of dlls.
  þ catch single-step + breakpoint exceptions (INT 01/INT 03)
  þ floating point status saved in SEH context if FPU is
    present
  þ bugfix: notifying the debugger of exceptions didn't work
    in the previous version.

  06/27/2005: version 2.8.17

  þ WriteConsoleInputA no longer dummy
  þ bugfix: Ctrl-Break now is always signaled and it is
    indicated correctly for Ctrl Handlerprocs        

  06/23/2005: version 2.8.16

  þ bugfix: ENHANCED_KEY flag now set for right Alt/Ctrl
  þ bugfix: wrong virtual key/scan code created F11/F12
  þ bugfix: wrong virtual key/scan code created Ctrl-Numpad5
  þ bugfix: wrong virtual key code created for Alt-Del 
  þ thread dispatcher now generates a single-step exception
    in any case (previously it omits that step when IOPL was 3).
    This will restrict LPMS usage to a minimum.
  þ bugfix: primary exception hander no longer pushes anything
    onto the client stack. This silently assumed that a stack
    switch has occured, which may *not* be true if LPMS is used
    already.
  þ bugfix: wrong VK code generated for Ctrl + Ins/Del/Home/End/Tab 
  þ bugfix: numlock/capslock/scrolllock control states not set
  þ bugfix: keys '+' , '-', '*', '/' on numpad were translated to
    wrong virtual key codes. numpad-/ will return VK_DIVIDE
    as in XP, not VK_OEM_MINUS as in 9x
  þ bugfix: VK_CLEAR (numpad-5) wasn't recognized
  þ bugfix: KEY_EVENT_RECORD.dwControlKeyState: ENHANCED_KEY 
    flag was never set.
  þ bugfix: AddAtomA, DeleteAtom, FindAtomA, GetAtomNameA
    were mistakenly documented as dummies.
  þ SetCurrentDirectoryW no longer dummy
  þ LFN support when running on NT platforms implemented
  þ clear TF in internal exception handler proc so a
    debugger doesn't stop there.

  06/14/2005: version 2.8.15

  þ SEH now supports floating point exceptions if such 
    exceptions are reported by Exception 10h. Regretably
    this isn't the case with most DPMI servers, but the 
    standard way - FPU exceptions reported by IRQ 0Dh - will
    definitely not work because of DPMI's stack switching
    thing :-(.
  þ Win32 exception handler now can work even if called with
    an invalid FS segment register.
  þ init mouse with soft reset and use int 33h, ax=0014h to
    set/restore mouse event proc.
  þ HeapCreate: non-growable heaps implemented
  þ if DKRNL32 gets out of its internal heap space, an error
    msg is displayed. Previously just a debug message was
    written in the debug version.
  þ SetConsoleMode: allow mouse to be deactivated

  06/07/2005: version 2.8.14

  þ CreateFileMappingW no longer dummy (but CreateFileMapping
    still doesn't support object name != NULL)

  06/05/2005: version 2.8.13

  þ bugfix: UnhandledExceptionFilter didn't call RtlUnwind if
    exception filter function returned EXCEPTION_EXECUTE_HANDLER
  þ bugfix: EXCEPTION_RECORD.ExceptionRecord wasn't initialized
  þ bugfix: if exception filter function in UnhandledExceptionFilter
    returned with EXCEPTION_EXECUTE_HANDLER this was handled like
    EXCEPTION_CONTINUE_SEARCH.

  06/02/2005: version 2.8.12

  þ bugfix: HeapDestroy may have failed to free all resources

    in versions 2.8.10 - 2.8.11.
  þ bugfix: DosDateTimeToFileTime() failed if seconds were just 60
  þ local times are supported if TZ environment variable is set.
    Daylight Saving Time is not supported.
  þ bugfix: SetFileTime() indicated a failure if "last access"
    or "creation" date/time couldn't be written. Now this
    errors are ignored if at least "last write" could be set.
  þ GetVolumeInformationA no longer dummy

  05/22/2005: version 2.8.11

  þ bugfix: SEH didn't work for more than one exception frame.
  þ RtlUnwind no longer dummy
  þ bugfix: if parameter lpDistancetoMoveHigh in function
    SetFilePointer isn't NULL, the dword it is pointing to
    now is set to ZERO on exit.

  þ bugfix: SetFilePointer didn't work with negative offsets
  þ bugfix: CreateDirectory set wrong error code [5] if directory
    already exists
  þ bugfix: WaitForMultipleObjects didn't return the correct
    value if parameter fWaitAll==FALSE

    no longer dummies
  þ Functions SetFileAttributesW, CreateDirectoryW, MoveFileW, 
    RemoveDirectoryW, GetCommandLineW, GetFullPathNameW,

  05/14/2005: version 2.8.9

  þ bugfix: GetCompressedFileSizeA now works with LFN
    and returns -1 on errors.
  þ EXCEPTION_ACCESS_VIOLOATION: EXCEPTION_RECORD now with
    2 arguments in ExceptionInformation field, as it may be
    expected (for most DPMI servers these fields are NULL, though)

  þ GetFileSize now uses int 21h, ax=71A6h if LFN supported
  þ GetFileInformationByHandle now uses int 21h, ax=71A6h if
    LFN installed. Else sets at least the date/time and size fields
  þ BugFix: FindFirstFileA: translate error code 0012 returned
    by int 21h, ax=4E00 to 0002
