Afaik:

FPM == Fast Page Memory. It was the `standard' memory for workstations
and PCs before EDO and SDRAM became popular. The 4 extra bits are for 
parity checking and have been dropped by most PC-manufacturers some
years ago to save a few bucks. I think a lot of '486 machines needed
36 bit memory at the time. Some manufactorers worked around it by
producing `fake' parity memory; 32 bit with some circuitry to similate
the parity. AFAIK that won't work on the Alpha's.

Feico.
