Earlier this year there were a couple of articles in Dr. Dobbs Journal which
outlined a procedure for determining not only what kind of video adapter is
resident in a PC, but also whether it has a color or monochrome tube
attached (except for CGA where you can't tell). Sorry, I don't recall which
issues, but it was in the column by Jeff Duntemann (or the late Kent Porter).

It is a simple algorithm, based on functions known to exist in the BIOS
extensions implemented in each type of card.


Good luck!
