BTW can you tell me why my PATA harddisk shows up as scsi (sd..) disk using ICH6M, using kernel with both plain ide and libata/piix enabled? I was under the impression that PATA harddisks should always show up as hd.. I tried two approaches and both sort of work: include the PCI id in the ide/piix list (disk/cd show up as hd..) or enable atapi in libata (disk/cd show up as sd/scd), although the latter tends to lock up hard every once in while, which is to be expected I assume. Just puzzled... Is there a possibility that dell attaches PATA harddisks using a SATA/PATA converter to the SATA connection of the ICH6M?
