In BaseSrvGetConsoleRecord and GetConsoleRecordBySessionId, check if the console record was not found instead
of returning the last one in the list.
In BaseSrvCheckVDM, return the session ID to the caller.

Restore the console to normal size while no DOS task is running and keep track
of the cursor position.
Adapted from a patch by Hermès Bélusca-Maïto.
svn path=/branches/ntvdm/; revision=63119
Use VdmRunning to keep the state of the whole VDM, not a VDM task.
Add an event whose signaled state determines the state of the VDM task.
Use FILE_SHARE_READ when opening executables.
svn path=/branches/ntvdm/; revision=63116
Make our BaseSrvGetNextVDMCommand and GetNextVDMCommand a bit more Windows-compatible,
and modify NTVDM accordingly.
svn path=/branches/ntvdm/; revision=63098
Implement BaseSrvDisconnect and BaseSrvCleanupVdmRecords, which will remove VDM console and DOS records
which have been left behind by a terminated ntvdm process.
Implement the "VDM voodoo" in BaseSrvCreateProcess. It's supposed to store the process ID of the VDM
in the VDM console record.
Fix minor bugs.
Add function declarations to the header file.
svn path=/branches/ntvdm/; revision=63042
When the CsrProcessCreateNewGroup (~= CREATE_NEW_PROCESS_GROUP) flag is set, it means that we are creating a new process group leader, and not the reverse :P
svn path=/branches/ntvdm/; revision=63041
Don't define STANDALONE by default.
Don't quit ntvdm after it becomes the last process on the console if a DOS app is still running.
svn path=/branches/ntvdm/; revision=63024
Rewrite DosCreateProcess, separating the loading code into DosLoadExecutable.
Implement INT 21h function AH = 0x4B (Create Process).
svn path=/branches/ntvdm/; revision=62972
Fix few DPRINTs. The DOS program starting code (common for STANDALONE and OS-integrated modes) can be moved into a helper function later on.
svn path=/branches/ntvdm/; revision=62688
Fix BaseSrvCheckVDM - DOS records should be initialized with a state of VDM_NOT_LOADED.
Fix BaseSrvFillCommandInfo - Check the size of the buffers.
Start implementing BaseSrvGetNextVDMCommand.
svn path=/branches/ntvdm/; revision=62683
Implement BaseSrvFillCommandInfo, a function that fills a BASE_GET_NEXT_VDM_COMMAND
structure with command information.
svn path=/branches/ntvdm/; revision=62602
- Move more constants to the global header.
- Implement GetConsoleRecordBySessionId.
- Implement BaseSrvUpdateVDMEntry.
- Improve and fix bugs in the cleanup code.
svn path=/branches/ntvdm/; revision=62451
Use a helper function for stopping the VDM (in case we add other steps for that), instead of just setting the flag to TRUE.
svn path=/branches/ntvdm/; revision=62378
Move the GET_NEXT_VDM_COMMAND_DATA structure to a global header, and
rename it to VDM_COMMAND_INFO.
Implement BaseSrvCopyCommand, which moves the BASE_CHECK_VDM structure data
into a new VDM_COMMAND_INFO structure.
Implement BaseSrvFreeVDMInfo which frees a VDM_COMMAND_INFO structure and
everything in it.

- Finally get rid of console output handles in the BIOS.
- Move console text buffer copy from BIOS back into VGA memory (~= revert part of r61542), but do it ONLY when attaching the VGA emulation to the console.
- Fix cursor positioning in BIOS & VGA (work in progress).
- Initialize PS/2 after having setting basic console modes.
- Showing/hiding mouse cursor (see the option in the console menu) is done in while() loops to be sure the cursor is really shown/hidden (based on the return value of ShowConsoleCursor).
svn path=/branches/ntvdm/; revision=62373
The RegisterConsoleVDM API (undocumented) allows NTVDM to get a VGA-like text framebuffer hold by the console server. This text framebuffer is unique, per-console (so that changing the active text screen buffer doesn't change the text framebuffer) and exists even if you use a graphics screen buffer.
NTVDM can write in this framebuffer, and when a call to InvalidateConsoleDIBits is done, it is painted on the screen.
Since RegisterConsoleVDM is unimplemented on ReactOS, I start an implementation of this API *inside* NTVDM (that will then be moved to kernel32/winsrv when it will work correctly).
I adapt the code of the VGA emulation to support RegisterConsoleVDM.
svn path=/branches/ntvdm/; revision=62371
Implement a function that creates a pair of event handles - BaseSrvCreatePairWaitHandles.
As already explained in the comments of BaseCheckForVDM (in kernel32), the hParent parameter
is actually an event handle (or more precisely, the client event handle), not a process handle.
svn path=/branches/ntvdm/; revision=62367
Get rid of ConsoleInput handles in the BIOS; setting input console modes should be done in the emulator.c module itself (when setting user interface modes), and if a mouse is present, handle it in the ps2.c module.
Next step will be to get rid of ConsoleOutput handle in the BIOS.

Be able to load an external DOS BIOS file (at 70:0000) and, in case it is the DOS BIOS file of the NT VDM, load the DOS kernel file ntdos.sys when the ntio.sys calls BOP DOS function 0x11 (and put the kernel at DI:0000).
Work in progress...
svn path=/branches/ntvdm/; revision=62343
- Add BOP 0x12 "BiosGetMemorySize" (same number as the corresponding INTerrupt). Needed by ntio.sys when initializing (see next commit).
- Use ASCII names for bios image and dos kernel files names.
- Use the file helper functions committed before for implementing ROM image file loading.
svn path=/branches/ntvdm/; revision=62342
- BIOS32: As a demonstration, load a BIOS expansion ROM (the one I've tested is the "OS in PCI expansion ROM" from: https://sites.google.com/site/pinczakko/building-a-kernel-in-pci-expansion-rom ; we don't support PCI thingies at all, but the bootstrap code works correctly).
- Initialize the BIOS32 stack for the callbacks.
- In the common BIOS functions, if we try to load the Windows NTVDM (SoftPC) BIOS (file: bios4.rom), we immediately hit a BOP 0x00 followed by INT 0x19 (bootstrap to run an OS). The BOP 0x00 is the function used by the BIOS to ask NTVDM to initialize the hardware, the IVT with data and so on. Also we finish to load the low part of the NTVDM BIOS in it (file: bios1.rom).
It's work-in-progress, nothing is done, there are lots of debugging code...
Have fun!
(to load a custom bios you need to put its filename as the first parameter of the BiosInitialize call, in the main() function in ntvdm.c).
svn path=/branches/ntvdm/; revision=62333
- Add utility functions for loading ROM images from files, and running them.
- Add a missing PVOID in the MEM_ALIGN_DOWN macro.
svn path=/branches/ntvdm/; revision=62332
- Reduce the size of the trampoline needed to perform 32 ---> 16 bit callbacks.
- Fix some comments, improve DPRINTs.
svn path=/branches/ntvdm/; revision=62331
- Move an "enable interrupts" command to where it belongs (i.e. in the BIOS32 initialization code; we do it at the very end). Otherwise some problems appears when trying to load 16-bit bios images.
- Use the new macro REAL_TO_PHYS to convert "real-mode" pointers (valid inside the VM only) into "physical" ones (valid in ROS/Windows/whatever).
- Add BIG HACKs (thanks Aleksander ;) ) in EmulatorRead/WriteMemory for wrapping up high memory addresses to low ones, so that we can load bios images (when you start running code at F000:FFF0).
To test 16-bit bios images: in ntvdm.c, put a valid bios file name in the BiosInitialize(...) call, and disable all DOS calls that happen before EmulatorSimulate().
svn path=/branches/ntvdm/; revision=62314
- BIOS location must be aligned on 32bit boundaries (or 16, I have to check). This fixes BIOS images loading when they miss a (null) byte to make them (e.g.) 8192 bytes long (example: the BIOS image of windows ntvdm).
- Add useful alignment (and others) macros.
