BIOS disassembled

Postby riq » Thu Jan 04, 2018 11:00 pm

Hi,

I know that the BIOS code is very well documented in the Technical Reference. But is has some issues:
- no very legible
- not easy to search
- no hyperlinks

so, I started to disassemble it, adding the original comments.
And I also started documenting the "test code" (the one that appears when you press ctrl+alt+ins).

This is still WIP, and I'll keep adding comments in the following weeks/months.

It is here:
