• For detailed instructions on RAID configurations, refer to the RAID manual in the

Support DVD.

• If you intend to create a Serial ATA RAID set using these connectors, set the OnChip

SATA Type item in the BIOS to [RAID]. See 2.3.4 SATA Configuration for details.

Serial ATA connectors (7-pin SATA1, SATA2, SATA3, SATA5, and SATA6)
These connectors are for the Serial ATA signal cables for Serial ATA 3Gb/s hard disk

and optical disk drives. The Serial ATA 3Gb/s is backward compatible with Serial ATA

1.5Gb/s specification. The data transfer rate of the Serial ATA 3Gb/s is faster than the

standard parallel ATA with 133 MB/s (Ultra DMA133). If you install Serial ATA hard disk

drives, you can create a RAID 0, RAID 1, and RAID 0+1 configurations through the

onboard SB700 chipset.

Install the Windows

XP Service Pack 1 before using Serial ATA.

The connector is for a serial (COM) port. Connect the serial port module cable to the

connector, then install the module to a slot opening at the back of the system chassis.
