Well, I have no performance specs on hand, but having the 386 get its
stuff from 35 ns static RAM instead of 60-80 ns dynamic RAM tells you 
something right there.  Also, on the IBM PS/2 Model 70 25Mhz machines, 
they found it important enough to give the top 128k to BIOS, so that 
it could be cached, instead of accessing ROM.
