Preliminary Information

3.2

Model-Specific Registers (MSR)

The AMD-K6-2E processor is based on and functionally

identical to the AMD-K6-2 processor Model 8/[F:8], which

provides ten model-specific registers (MSRs).

The value in the ECX register selects the MSR to be

addressed by the RDMSR and WRMSR instructions.

The values in EAX and EDX are used as inputs and outputs

by the RDMSR and WRMSR instructions.

Table 5 lists the MSRs and the corresponding value of the ECX

For more information about the MSRs, see the AMD-K6®

Processor BIOS Design Application Note, order #21329.

Fo r mo re in fo rma tio n ab o ut the RD MSR and WRMSR

instructions, see the AMD K86™ Family BIOS and Software Tools

Development Guide, order #21062.
