Pentium! Oh well. As that's what your going for, it would be a good idea if you optimised it for the pentium as well
, compiler optimisations and instruction pairings etc.
As for below Pentium cpuid, supported are:
Intel 486DX4 100 (but AFAIK not AMD 486DX4 100/120)
AMD Am5x86 133MHz
Possibly Cyrix 5x86
One special case though is the Cyrix 6x86. It had the CPUID instruction but it could be turned on/off, the default is OFF
.
Only a few BIOSs had an option to turn it on!
Will you be supporting Cyrix's Tim? (I'll test the mobius with a cyrix soon).
hope this helps.
