I hope that I'm not wrong in this forum - if yes please post me (a) link(s) to the right forum(s). Thanks.
Ok, here's my question:
I'm interested in cpu- and hardware close programming.By looking in my BIOS I found some strange RDMSR/WRMSR Register codes, which I couldn't find in any cpu developing manuals of Intel - Maybe could someone help me to (a link, an explanation) indentify it?
Here are the MSR register codes
For example a code snippet in my BIOS (AMIBIOS 8) looks like:
66 B9 41 01 01 C0 mov ecx, 0C0010141h
0F 32 rdmsr
66 83 C8 01 or eax, 1
0F 30 wrmsr
Is this a BIOS protection feature (strange MSR codes, maybe self modifying code ???) or do these registers really exist?
Thanks in advance
I'm moving this from the Intel AVX and CPU instructions forum. The compiler forums are a better place for general assembler questions, as the Intel compilers support inline assembly, and you will be more likely to get an answer here.
Thanks for your question.
