Summary: IDE drives on an an Intel PIIX4 controller show up as
SCSI devices (/dev/sdX)

In openSUSE 10.2 Beta1 my Intel 82371AB/EB/MB PIIX4 IDE controller is using the
ata_piix module instead of the piix module as its preferred driver. The result
is that my IDE drives appear to be SCSI drives (e.g. /dev/sdX instead of

I acknowledge that this may have been done on purpose, for reasons I am not
familiar with, by in my opinions it is bad to break the IDE/hdX SCSI/sdX model.

If I modify my /etc/fstab, /boot/grub/menu.lst, and INITRD_MODULES to use hdX
and piix then rebuild the ramdisk the devices come up and appear as /dev/hdX.

Attached is a hwinfo and my YaST logs. For convenience, the entry for my hard
drive controller from hwinfo follows:
