The SMART controller only supports SCSI disk drives. SCSI tape drives and CD-ROM drives are not supported.
The boot device must be logical drive 0 on the primary controller. Even though the BIOS lets you configure any controller as the primary controller, it will only let you boot from logical drive 0 on that controller.
If you want to change the RAID configuration, first delete the old configuration information using the EISA configuration utility. If you physically move the disks before deleting the RAID configuration (or the partition information on the logical drives), you may not be able to boot your system.
