Ah well, I guess I'll never know what happened.
I've been meaning to build a bigger, better, faster Linux box anyway. I'd been running an old spare-box P3 700MHz clunker while I learned Linux and decided whether I wanted to continue using it. I'm hooked.
I now have an old P4 1.5GHz box that just came in. Got no other use for it, so it's the new Linux box.
Stole a 80GB and a 40GB drives out of my #1 win-xp box for it and bought #1 a nice shiny pair of new 200GB NCQ drives for a new RAID0 array.
Sweeeeet!!!
