Not quite right...
The original Pentium chips were i586. Anything that is Pentium I + MMX is
still i586. Pentium Pro chips are i686 processors. PII chips are
(basically) Pentium Pro cores + MMX. Adding MMX does not make a major
architechtural change, so they are still i686. Same with the PIII
processor - no big changes. As far as I know, all they did was play with
the cache between PII and PIII. I don't know about Coppermine and such -
I need to keep up to date with this - but I do know that AMD's Athlon is
the first i786 processor to be sold. The Pentium Pro, II, and III
processors are all i686. Whether or not the chip supports MMX does not
change the architechture number.

Sorry, can't help you here. I have no idea what the S means.
