After some hacking around with some x86 assembly and reviewing some example code from the EMS Flash Board project, I was successfully able to get my hijacked video int10h working! It's been a long time since I felt such excitement in seeing a DOS prompt!
NOTE: now that I have it working at this level, I have to decide where to go to next.... color/attributes support? VGA support? DVI-D? graphics?
