[comp.lang.c] How to recognize CGA and EGA/VGA ?

snguyen@nprdc.arpa (Son Nguyen) (12/21/88)

Does anyone know how to detect whether an IBM PC has a CGA or a EGA/VGA  ?
What I mean is that how can I write a small function just to find out about
my machine graphic adapter ?   I know how to access the memory for CGA but
I don't know how for EGA/VGA.

Thanks.
