I acted on your suggestion and installed version 1.4 of the TVGA8900C driver for Windows 3.1. It works in both the 800x600x8 and 1024x768x8 bit modes.
Actually you can get even more than 8bpp (which I thought your original question was - misreaded it). You need to get the newer trident drivers uc51-win.exe and you'll be able to get 16bpp by using the trix800.drv. But you'll need to switch your X server to 16bpp either because the dosemu doesn't support 16bpp->32bpp remapping :(
HOWEVER, this Trident driver conflicts with Video For Windows 1.1 and I haven't been able to find a newer version of the Trident driver which fixes the problem.
Newer version doesn't help :( The problem is not in the driver itself but in the vtdapi.386 that dosemu emulates by using the code stolen from wine. And this doesn't work. I think perhaps dosemu needs the LE loader so that it could load and use the native .386 drivers. They may require ring0, but most of them are likely only need the hardware access, which is not a problem. Any ideas where is some LE loader code in C can be stolen? :)
When I attempt to change virtual memory settings, I'm getting an error about nonstandard Windows files. Consequently, I can't change virtual memory settings with krnl386.exe.
Virtual memory in windows is handled by the VxD code which is not in dosemu. And you don't need it anyway because the virtual memory is provided by Linux kernel. Duplicating that functionality under dosemu is possible (32rtm can do this), but there is no real use because the Linux kernel does it more effectively. So if you need more memory to your Windows app, just increase the $_dpmi value in dosemu.conf, and Linux will do the rest.
