the message I get when I boot the system is

Serial ATA AHCI BIOS, Version iSrc .........

Controller Bus#00, Device#1F, Function#02: 03 Ports, 01 Devices
Port-00: Hard Disk WDC WD320.............
(This drive is controlled by the RAID BIOS)
Poer-01: No Device detected:
Poer-04: No Device detected
AHCI BIOS not installed
.
.
.
Drive 1 not found: Serial ATA, SATA-1
Drive 4 not found: Serial ATA, SATA-1
Strike the F1 key to continue, F2 to run the setup utility


Funny thing is is that at Splash I can tap F12 and select Boot Device Menu'
* WDC WD320 and it will boot just fine.


Can someone lead me to the right way to get this system to boot without manually interrupting the boot sequence???
