 hello, thanks for your quick repsonses. Well, it wasnt so much really
that i wanted to get any more data integrity or performance out of my
box. i bought the card a few months ago off and friend, and it came
obsolete when i bought a new motherboard that supported UDMA66 anyway, i
was just doing it for fun (besides the fact i wouldnt trust any hardware
*I* modified to go into a production server) :) i was just wondering if
i could get some more use out of an old card. thanks for helping though.
sean
