That's right.   You don't want EDO ram if you care about reliability -
it buys you about a 5% speed boost but eliminates the possibility of
error checking.   Really bad design, IMHO - there's nothing about EDO
per se that prohibits ECC - they just chose not to make it possible.

My Adaptec controller, which is a 2940, has a tendency to lock my
system up during periods of intense I/O.   For example, the nightly
file system checks.   I would expect the 2940W to behave the same way
- I believe the chipset is identical.
