When running Windows for Workgroups 3.11 at any color bit depth above 256, Windows says it can't get get the driver to work. I am emulating an et4000 with the proper drivers on Mac OS X 10.6.4.
The ET4000 emulation doesn't support more than 256 colors. There's a patch here though that it might work with: ID 2900295
Nah. Doesn't work for me.
