- Judging by the BIOS date (which is old for an IBM AT; I guess this
- is a model 039) it should by 6 MHz. That BIOS does not support
- the 101-key enhanced keyboard.

-
- That motherboard is pretty much the standard as far as compatibility goes.
- It would probably be better to upgrade to the final (11/85) PC-AT BIOS
- but there are no longer any "official" sources for that.
