Its recent. I bought the thing only some number of months ago.
The basic mobo design is 2-3 years old, though, its not bleeding edge,
it was meant to be a conservative, stable, functional choice.
I'd hope that they'd have things like this debugged by now. Sigh.

No See other email. memtest86 passes fine, the system has been in
heavy use as a compute server on large datasets. No problems at all,
spotless record. I've beeb manipulating multi-gigabyte files just fine
on the IDE disk, without any corruption at all. I can move them
around on NFS, too. They only get corrupted in the SATA disk,
where its immediate and widespread, and takes less than a minute
to occur.

I'll give tht a whirl. Bios settings are still at factory defaults, I had no
reason to mess with them.
