The AMD chip *does* pick up a pin signal from the, but this signal
only tells the chip whether to internally double, triple, or quadruple.
(Interestingly, on this chip the signal which would say 'double' to an Intel
chip is the 'quadruple' command.)   However, this 4x is *not* overclocking - 
this is the *usual* way to run the AMD586. The only way to up the speed to
over 100mhz on the 25mhz TP701 would be to step up the 701's MB speed.

I've never heard of a chip which could be 'overclocked' by somehow upping
the internal clock multiplier to an unsupported multiple (like 6x).  Doesn't
mean they don't exist, but I *have* done a lot of homework on this.
