This may have changed with the later models, but on my 750, all parity
checking did was warn you of 1-bit memory errors. While this is
useful, it's nothing you couldn't find out with a program (or OS) that
rigorously tests or works the memory (like OS/2, NT, or Linux).
Some EISA machines and possibly PCI machines have this neat feature
where if the parity memory indicates an error, the computer will map
around it. You lose a few bytes (few k?) of RAM, but the memory
SIMM/DIMM/card is still usable.
