I'm looking for a clean, safe way to determine what kind of display is being
used on a PC or PS/2 type machine. ie: I want to know if there is either no
display adapter, or monochrome, or cga, ega, vga colour, vga paperwhite, mcga,
pga. I don't care which brand of card it is... I'm not worrying about whether
the Vga chip set is Tseng or CHIPS, or ... I'm trying to do this in
assembler. Any ideas out there?
thanks in advance

Pick up the latest interrupt list on simtel20. INTER490.ZIP is the
filename you are looking for. It is what I detailed the current
PCcurses 1.5 beta release hardware detection (all in C) on.

If you want to discover what the display mode is, check memory location 0040h:0049h. It is a byte that defines the current display mode.
