I just got a new PC with NT4, and am having problems doing support work on old P-CAD designs.
   

My video card doesn't have full VESA compatibility built into the BIOS. You have to run some VESA BIOS Extension TSR that ATI made for their Mach64 card. My new integrated card is a 3D Rage Pro AGP 2X, and it doesn't work well with those TSR's  under NT4's "quasi-DOS". Apparently they do work under win95 or win98 flavor of DOS.

The P-CAD driver DVESA256.REX sort of works when I boot to DOS (obviously not the right driver though). All the other P-CAD drivers are coming up in 640 x 480. Anytime I try to run from NT4 in a DOS window, the best I get is 640 x 480 (we have a serial key...)
   

If anyone knows of a nice 2D or 2D/3D graphics card (prefer AGP) that has full VESA compatibility (without relying on some BIOS extension TSR) and will work with P-CAD on an NT4 box, please drop me a line.
