The bios has a scan sequence which is set low to high or high to low of the
pci devices.  You can swap the scan sequence around and it should work.

I assume you mean PERC 3/DC.  It's an add-in card, the 3/Di isn't.

1) BIOS must be set to boot from the PERC2, not the PERC 3/DC.  This is a
config option in the Setup screen available immediately after power-on.
2) Linux must think that the PERC2 is your boot device.  This means that
/etc/modules.conf needs to list the aacraid driver first, the megaraid
driver second.  If that's backward, it won't work.  Fix that, remake your
initrd, and reboot.
