AMD Athlon™ Processor Model 6 Revision Guide

24332G—October 2003

Preliminary Information

19

Processor Does Not Support Reliable Microcode Patch Mechanism

Products Affected. A5

Normal Specified Operation. The processor should function properly after a microcode patch is loaded.

Non-conformance. The processor has the patch RAM BIST function disabled. Since BIST is not run on the
patch RAM, reliable operation of the patch RAM cannot be guaranteed. Therefore it should not be
used.

Potential Effect on System. When a microcode patch is loaded, the system may not behave properly.

Suggested Workaround. Do not load a microcode patch.

Resolution Status. Fix planned for a future revision.
