[geeks] FreeBSD install problem on ALR server

That is similar to the old 486sx chips - Intel only had one chip "die", but they would test them and see if the math coprocessor would work on a given chip, that decide sx/dx designation for the CPU (sx had math coprocessor connection it was never "activated"). Then the chips were speed-tested, and sorted according to reliability, and then marked according to customer demand. This basic process continues to this day, except, of course, all CPUs have a mth coprocessor on board.

This is how you get a P/75 marked CPU that can run up to 166 MHz...

BTW the math coprocessoer was another 486 with the coprocessor enabled - it disabled the previously installed 486sx CPU!

1meg ppros are actually really funky beasts.  As in all ppros there is one
proc die (the actual processor core) and unlike all others there are 2
512k cache die.  Most ppros have either one 512k cache die, or one 512k
cache die with half of it bad/disabled/something.
