I tried writing assembly code like this:

mov ecx, 0xc0000082
rdmsr

I tried this instruction on an old CPU, AMD Dual-Core C70 Processor, x86 Architecture. When I try to debug I get a Segmentation error in the rdmsr instruction.

There are solutions, tricks or what should I do? or does the rdmsr instruction not support x86 processors?

I read a little documentation that the instructions support older processors such as Pentium I, etc.
