I finally did it and bought a multiscan monitor and a VGA card! Now the fun
begins:

I have a Mini-Micro Supply Company 20MHz 386 with an on board enhanced EGA
adapter. (When I bought the machine I new I would eventually go from monochrome
to a VGA color system. The dealer explained that I could disable the on board
EGA if I wished.)

Now, the monitor (Packard Bell Uniscan) works fine with the EGA (even enhanced
640x480 x 16 color mode); but, when I try to disable the EGA card (one switch)
and plug in the Everex EVGA card the computer DOES NOT BOOT! If I don't disable
the EGA the machine beeps a few times and then hangs.

I assume there is a compatibility problem between the EGA BIOS(?) that was not
completely disabled and the EVGA BIOS, but I'm not positive. Anyone out there
have any similar problems and solutions(?). I do have a call into Everex 
Tech. Support (is there a net address for them?) but I don't know how long
it will take for them to solve the problem.

I appreciate any help I can get. Thanks in advance
