It was never intended to do DOS. It was an embedded controller. Most
of the peripherals were not PC compliant and they certainly weren't
mapped at the right IO addresses.
In fact, Intel made it a point to tweak the embedded controllers so
that they *could not* run DOS and they could sell them at embedded
processor prices. Witness the 80376 and 80386EX.
Can I ask you more about these counter-DOS tweakings? Just interesting...
