REP MOVS Instruction with Overlapping Source and Destination may Result in Data Corruption OK guys. This is a multi-byte memory move operation. From what I have learned by reading this thread that involves only the processor, FSB and memory. So exactly how does a BIOS patch fix this? I seem to recall something about bios settable values that controlled the execution of various stages of the Athlon (disabling an FP unit originally) so presumably the P4 has the same. But they can only disable stuff can't they? So what are they disabling? Sounds like it must be a cache to me. In which case I definitely we should get some benchmarks with the new bios.
