Embedded AMD-K6 Processors BIOS Design Guide
23913A/0—November 2000
Preliminary Information
All AMD-K6 processor models belong to instruction family 5 (as
returned in EAX by function 1). All AMD Athlon processor
models belong to instruction family 6 (as returned in EAX by
function 1).
Figure 29 shows the contents of the EAX register obtained by
function 1. Table 29 summarizes the specific processor
signature values returned for AMD processors.
