I got to the part about int 10 -- the display set-up interrupt and had a thought. The monitor that I had seemed to recreate Nick's display problem is EGA/XGA. Nick, please check yours as well. In the case that it is, we will need to enter a new display mode setter other than 0x4F02H, which is specifically VBE, the Vesa superVGA setting setter. VESA monitors seem to be set to 0x117h, 0x118h, and 0x123h successfully. I don't believe anyone has tested the EGA/XGA settings. Wikipedia has this to say: http://en.wikipedia.org/wiki/XGA My projects are many and I keep flipping from one to the next. I do have an XGA monitor, and if we can get some concensus on how to preceed here, I'll try out some of those ideas. BUT, I suggest a VESA-VBE superVGA monitor. Used, they are cheap. Bet you can find one in a friends garage if not your own. :-) Getting the superVGA means not having to worry about hacking the already well tested code. Much luck!
