Hi,
Read somewhere that the 6x86MX is PentiumII code compatible, but these
processors are listed as two separate options under the kernel config
(2.4.21)
Will a kernel/apps compiled for PII run on a 6x86MX?
Thanks,
Asfand Yar

I don't know the details in this particular case. However, even if
two CPUs are object code compatible, it doesn't mean that instruction
scheduling, caching and such things behave the same way. Code
optimized for one CPU might not be optimal for another, even if it
runs.

You could try, but I wouldn't recommend it. IBM/Cyrix 6x86MX is more
like CONFIG_M586MMX. It's a souped up Pentium really (read not P6).
