States after RESET and INIT
Embedded AMD-K6 Processors BIOS Design Guide
23913A/0—November 2000
Preliminary Information
States after RESET and INIT
Register States after RESET and INIT
After the processor has completed its initialization following
the recognition of an asserted RESET or INIT signal, the states
of all architecture registers and MSRs are compatible with
those of Pentium processors. Differences are listed in Table 2
through Table 4.

2. “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.
“M” represents the Model and “S” represents the Stepping.
