2-26 Chapter 2: Hardware information
6. Serial ATA RAID connectors (7-pin SATA_RAID1, SATA_RAID2)
These Serial ATA connectors support SATA hard disks that you may
configure as a RAID set. Through the onboard Promise
® PDC20378
RAID controller, you may create a RAID0, RAID1, RAID0+1, or multi-
RAID configuration.
1. If you wish to create a RAID set, make sure that you have
connected the SATA cable and installed Serial ATA devices. You
cannot enter the SATARaid™ utility and SATA BIOS setup during
POST if there are no connected Serial ATA devices.
2. The Promise ® PDC20378 RAID controller does not support ATAPI
devices such as CD-ROMs, DVD-ROMs, etc.
3. For RAID 0 and RAID 1 configurations, use both Parallel ATA and
Serial ATA devices for better performance.
