Notes:
1. The contents of EAX indicate if BIST was successful. If EAX = 0000_0000h, then BIST
was successful. If EAX is non-zero, BIST failed.
2. EDX contains the AMD-K5 processor signature, which is comprised of the instruction
family, model, and stepping.
3. These MSRs are described in
“AMD-K5 Processor x86 Architecture Extensions” on
page 57.
4. The AMD-K5 processor supports write allocate only on Models 1, 2, and 3, with a
Stepping of 4 or greater.
