System Booting Off SATA HDD Instead of SCSI

[mcfly1204]

I have a Compaq ML530 G1 with a 5300 array controller with mirrored drives that have Server 2003 installed on them. I have recently installed a PCI SATA controller with a new SATA HDD connected, but now the system attempts to boot off the SATA drive as opposed to the mirrored SCSI HDDs.

I have run the SCU to set the 5300 array controller as the boot device, but the system will continue to look at the SATA HDD. Any thoughts?

Who would have thought that moving the SATA controller out of the primary PCI slot would fix the issue....
