Edit /etc/modprobe.conf and add alias scsi_hostadapter2 ahci
Then rebuild your initrd with mkinird mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r)
Then reboot and make the BIOS change. This should give you much better disk performance.

John.
By the time I received this message I had already installed the ia_64 version of CentOS-5.2 with the BIOS set to IDE emulation. If now I change the BIOS to use RAID then the system cannot see the SATA drive at all.
Is it possible to change the BIOS setting to RAID and subsequently load the necessary drivers from the boot DVD without having to reinstall the entire system?
If so, then what is the procedure?
