Ignore RDMSR/WRMSR on undefined registers. Normally the CPU will fire an Invalid Opcode exception in that case.

This option is off by default, enable if using software or drivers that assumes the presence of
certain MSR registers without checking.

If you are using certain versions of the 3Dfx glide drivers for MS-DOS you will need to set this to TRUE as 3Dfx appears to have coded GLIDE2.OVL to assume the presence of Pentium Pro/Pentium II MTRR registers.
