What I had to do for the cn700 was vm86+bochs bios. Copy the bochs bios to
0xf0000, then run the vga bios (minus the console init part). Unfortunately,
all that work went down the tubes when I got my new laptop and completely
screwed up the file transfer. I've been trying to redo it, but I've had
other projects to work on, too. Good luck!
