amoeba@pawl.rpi.edu (Christo William Kmosko) (02/02/90)

 I've seen a few posts on this topic previously around, but havent managed to hunt down any of the replies, if they existed.  
  I can program all the modes of the 512K VGA card (640x640x256, 800x600x256 and 1024x768x16) fine... THROUGH BIOS...   can anyone tell me how to access the card DIRECTLY??? (Such as something like $B800:0000 for CGA) I've tried various memory locations, but I assume I have to set some port location to a specific value to write to the card... any help would be appreciated.. also, if you could repost the information on where I can get intouch with Trident Microsystems, I'd be very appreciative..

    thanks..
