Arrghh don't do this to me I don't need to add another OS to my compatibility list. heh

Can't remember if the additions for vmware support OpenGL for NT3.51/NT4 guests but I'd imagine that even if it did it would be alot slower than NT4 due to video drivers being in user mode.

I do have some old laptops with Rage video cards that should support NT3.51 fine but it's nowhere near a priority for me.

I've seen this on one of Nathan's Sick Windows Tricks once.

Pretty darn cool, but I thought Deus Ex didn't have a Software Renderer. Fully unsupported I suppose?

Yeah, I emailed that to him. It's on the Sick Windows Tricks 3 page. On VirtualBox I actually get a decent framerate on most of these games. I heard a passing comment on one forum that Quake 3 can be tricked into running on NT 3.51. That isn't an option because there's no way I could get OpenGL working.

Not even by dropping a Silicon Graphics for Windows/Cosmo Player opengl.dll/cosmord11.dll into the Q3 folder renaming it to opengl32.dll for functional but slow software rendering?

I suppose that would work for OpenGL, but it refuses to run if it detects a version of Windows NT < 4. WinQuake and Quake II do the same thing. Besides, all of the Unreal engine games are actually playable with a decent frame rate. I don't think there is any way you could do the same with Quake 3.

I remember wanting to try this ever since I saw it on ToastyTech. I'm actually somewhat surprised sound works, given the lack of DirectX in NT 3.51.

Generally these refined game engines have GDI and Waveout fallbacks for lack fo DirectX, Quake included

though in quake's case there's a hard version check against anything under version 4. Is there anything like KernelEx or Compatibiltiy mode to fake that for 3.51?

Everything I'm reading is saying that on 3.51/NT4 Directsound is emulated then outputted using MME.

Guess we could ask Raymond (oldnewthing)

You are right:

1if (!GetVersionEx (&vinfo))
2		Sys_Error ("Couldn't get OS info");
3
4	if (vinfo.dwMajorVersion < 4)
5		Sys_Error ("Quake2 requires windows version 4 or greater");
6	if (vinfo.dwPlatformId == VER_PLATFORM_WIN32s)
7		Sys_Error ("Quake2 doesn't run on Win32s");
8	else if ( vinfo.dwPlatformId == VER_PLATFORM_WIN32_WINDOWS )
9		s_win95 = true;

Any idea why that might be?

It's called not supporting the OS if there's no good reason to from the business perspective (usually).
