Source for a BBS loader with copper bars, a scrollie, altered text characters, and an adlib player - Copious comments and tight source. They even do checks for the proper equipment, i.e. VGA and a 386. Comes with docs on programming the adlib and SB fm chips. Comments are in Portuguese.
Source to detect which intel chip is in a computer - Detects the processor for sure, but does it by checking for invalid opcodes. If you need to detect CPU type, I suggest /code/hardware/processor/cpuid3.zip.
