ok, happily goofing around with the machine, when poof...  same memory
error as before.  this time i got an hour or so of use out of it before
it crashed.  the PRESTOserve card seems to not be the cause of the problem
but rather a symptom.

test reports that memory board 10 is bad...

?TFL:  3/mem (2: board 10: too many SBEs: 1048576) [KN03-AA]

is this typical of a bad card or a bad slot?  or will i have to experiment
to find out?  i'll probably experiment anyway.
