Hi, While I'm looking over this, do you have a mode in which the AHCI driver loads successfully? If so, look for a kernel message similar to this one: ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 4 ports 1.5 Gbps 0x5 impl SATA mode and post it, please. (I think that it won't say "SATA mode".) The "prog-if" value of 80 from your lspci output is interesting to me: 0000:00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 03) (prog-if 80 [Master]) Thanks, --- ~Randy
