I'll gladly provide any more information I've forgotten. See REPORTING-BUGS for the sort of information you should provide. This is a "it doesn't work" report without much more info. I would suggest doing a "modprobe ata_piix" or "modprobe ahci" (depending on ICH7 mode and hardware) and see what happens in 'dmesg'. Jeff
