  • Curious about this one, and interested to see if things have progressed at all.

  • The 386EX board is able to load MSDOS; however, the BIOS is not sufficiently IBM-compatible to run MSDOS. Since MSDOS loads correctly from a CF card in an IDE adapter, I would think any other OS would do the same. This is a project I would like to get back to because I now have a good idea of where the "IBM PC/AT" BIOS incompatibility lies. I have no plans at this time to actively work on the BIOS.
