I have this pseudo intelligent IDE controller from GSI. It says to not have Shadowing on when you're configuring drives, which I would guess putting booteasy or OS/BS on would qualify. > > I installed 2.2 Beta as from what I read, 2.1.[56] wouldn't be able to > > handle sd0 as sd0 when it's not the first BIOS disk. > > Well, sort of.

Like I said, pseudo intelligent controller. Thanks, Paul. -- Women aren't as smart as they think. They don't realize how little we know! - Tim Allen, Home Improvement
