Strange ports....

Post by ComputerPsi »

Hello all. At the moment, I am trying to disassemble and understand my BIOS ROM (Compaq pentium 3), for learning purposes. Anyway, at some point I ran into the ROM contacting I/O ports F860, F861, F866, F868, and F86E. I'll probably find some more. Does anybody know what these port are for? At least generally? I couldn't find a thing about them..
