This connector supports either RAID 0 or RAID 1 configuration through
the onboard Promise

PDC20378 controller. You can connect two
UltraATA133 hard disks to this connector and set up a disk array
configuration. You may also set up the UltraATA133 hard disks with the
Serial ATA hard disks on the Serial ATA RAID connectors to create a
multi-RAID configuration. See Chapter 5 for details on RAID
configuration.
1. If you wish to create a RAID set using UltraATA hard disks, make
sure that you have connected the UltraATA cable and installed
UltraATA 133 hard disks.
2. The Promise PDC20376 RAID controller does not support ATAPI
devices such as CD-ROMs, DVD-ROMs, etc.
