I just got my first look at: ``AMD x86-64 Programmer's Manual Volumue 2 System Programming''
There isn't enough information in there to program a BIOS for the hammer, as there are no memory controller docs, but AMD has finally documented there interesting MSRs such as: SYSCFG, the IO Range registers, and TOP_MEM. So it looks like I can release LinuxBIOS on the dual Athlon. Darn, now I have to find all of that code... :) Eric
