Well, I did a little bit of DEBUGing on programs that detect the existance of VGA and goes into 80x50 mode, and found the following code: mov ax,1112h ; go into 80x50 mode sub bl,bl int 10h This will switch the VGA card into 80x50 mode. I suggest you play around with the content of AX to get 80x43 mode. E. Teng Ong (ong@d.cs.okstate.edu) Computer Science Dept.
