A little off topic, so reply off list please

I am trying to get a video card working under X and I need to
find out some info on the card. It has a Chips and Technology
65530 chip on it and I need to do an interupt 10 call in assembly
language to get it. Any idea how this is done in Debug. Here is
the info I have

I know it would be much easier to just use a supported card but
this will run a flat panel display that I would like to use, and I thought
I would give it a try. If I can get it to work I plan on making a control
panel for EMC with the display and switches grafted onto an old
keyboard circuit board
Int 10/AX=5F00h

Chips & Technologies Extended BIOS - RETURN CHIP INFORMATION
AX = 5F00h
Return:AL = 5Fh function supported
BL = chip type (see #0106)
BH = video memory size (00h 256KB, 01h 512KB, 02h 1MB)
CX = miscellaneous information (see #0107)

See Also: AX=5F01h
