Playing around with Bochs, an x86 emulator. I tried to run colorForth on it, but unfortunately Bochs doesn't yet support non-DMA mode for the floppy driver. The PM1.COM test program worked from geezer's (Christopher Giese's) protected mode examples, running under FreeDOS 1.0. They don't seem to be very compatible -- Bochs complains "HALT instruction encountered in the BIOS ROM" -- but selecting "Continue and don't ask again" allows it to run anyway. I'll see if I can come up with some simple instructions for installing a working FreeDOS under Bochs, as I couldn't find such, but don't hold your breath...
