   Older MMX CPUs can be overclocked.  Newer ones are 'locked' and
cannot be overclocked by changing the multiplier.
   In any case for 'classic' Socket 7 motherboards 3.5X is the maximum
available, as BF2 simply isn't there, and I doubt the CPU would pay
attention to it if you patch-wired the pin.

  The only reference I can find suggests that S = Staggered! The docs
state that unless otherwise noted all Pentiums are SPGA.
