I want to run a proprietary program which does the following things:
... fh =
CreateFileA("C:\WINDOWS\system32\DRIVERS\BIOSMAP.SYS",
...); ... dh = CreateFileA("\.\BIOSMAP", ...); ... r = DeviceIoControl(dh, 0x10000000, ...); ...
On recieving 0x10000000 code BIOSMAP maps BIOS content (brand, creation date, etc) to some area and returns address of one null-terminated string from it to main program.
Is there a way to re-implement a SYS-file (so that main program would run w/o any change) like it's done with some VXD's in Wine-tree?
I wish :~(.
Can I get some examples?
You cannot use a VxD since they don't get considered for ioctl codes above 0x0000FFFF.
I made an example that uses a Linux kernel module that does the equivalent of USBSCAN.SYS. Basically you hack away at CreateFile() in KERNEL32.DLL to get it to open() /dev/... (a device node hooked up to the kernel module) and then use wine_server_register_fd() (or something like that) to register the file descriptor. Then you need to change NtDeviceIoControl() in NTDLL.DLL so that it actually does an ioctl() call to the kernel module. You'll have to use wine_server_handle_to_fd() to get the file descriptor for the first parameter of the ioctl(), and then wine_server_release_handle() after, and you'll have to make a custom struct that gets passed around as the third parameter in the ioctl(). Of course, the hardest part is writing the kernel module...
I'll probably put up my example on the net in a week or so.
There is also some people working on a user-space device-driver system for wine (an out-of-process server emulating NTOSKRNL.EXE), they've gotten some results, but they've been quite mysterious and silent about it...
Hope to get your answer, Anton Litvinov
