I sure hope someone gets some of these machines one day and finds all
our spam enlightening Bernard :)

The jibberish characters in the detected version of the card is not good
yeah?  They don't quite reproduce via the cut and paste, but I laughed
when I saw them on the weekend.

This is a default woody 2.2.20 kernel that i chucked on in a rush
install on the weekend, though it is an old machine, I guess I should
really get with the times and hit 2.4.x

========================

I see it has a Mail Box in it too, excellent ... maybe I can use the
megaraid card instead of SuSE Openexchange Server :P

Also, something else about these cards, though you'd be stupid to use an
LPr as a gateway or home machine because they have lots of high volume
fans and sound like a jet engine, if you did and the RAID mirroring
fails, you'll be woken by a monotone and inappropriately loud beeping
during the entire auto-rebuild process.  I had lots of evil stares at
work today from that :)  The crafty engineers put the transducer on the
under-side of the card.  

That kind of reduces the need to monitor it, you could hear it from the
next suburb before you got the email.
