Hard drive detection order

I think you need to go into the Perc 3/DC BIOS and disable the BIOS,
leaving only the Perc 3/Di BIOS active. Because you don't want to boot
off the Perc 3/DC, you do not need BIOS support on that controller. Linux
should still detect the Perc 3/DC on the PCI BUS and allow access to the
disks in the array.

We have a PV200S directly attached to a PE2650 through a Perc 3DC with
about 700GBs of RAID 5. The 2650 also comes with an internal (infamous)
card for RAID 0 on 2 internal disks. The problem we are having is while
installing Rocks cluster dist (I understand its based on RHEL 3), the
installer detects the external RAID first, thus assigning it /dev/sda
internal RAID becomes /dev/sdb. This causes several headaches while
OS. The installer by default prefers /dev/sda to install the OS image.
I checked the hard drive detection order in the BIOS and Perc 3DC is listed
last after the Perc 3Di.
Has anyone noticed anthing like this before? Am I missing something obvious
here? If not, how can I reverse the HD detection order?
