586 is Pentium (including MMX) 686 covers PII, PIII, Celeron, etc.
Don't forget the Pentium Pro is actually the start of the i686 chain.
The version of the 2.5.70 kernel with MMX seemed to be sort of sluggish. The 686 compiled Red Hat versions seem to work alright. My processor information is below. Which is part of my confusion.
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 5
model name : Pentium II (Deschutes)
stepping : 0
cpu MHz : 233.293
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr
bogomips : 465.30
The family being 6 and the model being 5 add even more to my confusion. I'll have to check out what a pentium pro actually is.
Thanks for the answer. I first thought that the PII was a Pentium with a lower core voltage. I wasn't sure if there was any difference in the instruction sets within the processors. >For Red Hat kernels, I have been selecting the i686 kernels, for my PII with MMX. After being exposed to more names, like dechutes, Celeron (pre-coppermine), coppermine, etc: I was getting a bit confused. >I haven't seen any errors with the i686 on the PII MMX. I did have program failures with the MMX version of the 2.5.70 kernel. I was wondering if I should have selected PII over the MMX, since there isn't an option for a PII with MMX.
Thanks for the P-Pro as the starting point for the split to the i686. My coppermine works great with that archetecture. The Deschutes confused me the most with the Celeron also being a PII.
There is no such thing as a PII without MMX. The only i686 processor without MMX is the P-Pro.
I'll try to compile my next kernel as an i686, then another as an i586, to see which is the best for this slow machine.
thanks,
Jim
