Booted from the LiveCD:

I keep getting "Buffer I/O error on device i2o_hda, logical block #" (the # goes from 0-3 each time I try to access the drive).

I've poked around and tried the acpi=off option and with that I lose the /dev/i2o device...any further suggestions?

I tried another distro on a lark and it installs to it...(Ubuntu Server 7.10). However, I'm much more a fan of Gentoo (kinda more of what I know). Figuring what they loaded different is a challenge though. I think I've tried loading all I could find from lsmod on the working setup to get it to read the drive contents...does anything jump out to you guys?
