Notes:

1. The contents of EAX indicate if BIST was successful. If EAX = 0000_0000h, BIST was successful.

If EAX is non-zero, BIST failed.

2. EDX contains the AMD-K6-2E processor signature, where X indicates the processor Stepping

ID.

3. The contents of these registers are preserved following the recognition of INIT.

4. The CD and NW bits of CR0 are preserved following the recognition of INIT.

5. “S” represents the Stepping. “B” represents PSOR[3:0], where PSOR[3] equals 0, and

PSOR[2:0] is equal to the value of the BF[2:0] signals sampled during the falling transition of

RESET.
