Set Mainboard CMOS Boot sequence to boot to ATA133 Raid Card On some Mainboard BIOS, it is necessary to set the Boot sequence to “SCSI, A:, C:” since the ATA133 Raid Card is identified as a SCSI card.
Using an Onboard IDE Card with ATA 133 RAID card If an onboard IDE controller is installed with hard disks, enable support in the Mainboard Standard CMOS Setup for the drives. Note that the onboard IDE hard drives will then be the bootable hard disk unless the system BIOS has a boot sequence setting with the option to specify booting to a different device.
