1 Hi Isern,

3 I actually have the exact same problem, and someone was kind enough to
4 help me so I'll pass on the same info. Basically my problem was that I
5 hadn't enabled the proper IDE Chipset (or SCSI if you use S-ATA) in the
6 kernel. When I booted off my Gentoo install cd, I can 'lspci -v' which
7 showed me what type of chipset I was looking for to enable in the
8 kernel. Give that a try and it should solve your problem.
