Hey, has anybody ever been able to find an AMD document called "AMD Athlon and AMD Duron Processor BIOS, Software, and Debug Developers Guide, order# 21656"? I can't find it on Google, Bitsavers, AMD's website, or ChipDB's datasheets section. I want to add Athlon emulation in 86box, but I just can't find ANY documentation on the AMD Athlon's MSRs. I'd add this emulation to MAME also, but there is currently no i386 dynarec in MAME, and I'm frankly too intimidated by the sheer MAGNITUDE of changes needed to make that happen.
