3.RAID ATA/133/100/66/33 connectors (40-1 pin ATAIDE1, ATAIDE2) (on RAID models only)

These connectors support either RAID 0 or RAID 1 configuration through the onboard RAID controller chip. You can use the RAID feature to set up a disk array configuration and to support additional IDE devices. You can install a total of four hard disks, two on each connector. However, only two can function in a RAID. For a high performance RAID 0 or RAID 1 configuration, always use two separate ATAIDE ribbon cables, one for the primary RAID IDE connector and another for the secondary RAID IDE connector.

To use the RAID feature, make sure that the RAID_SW jumper is enabled (set to pins 1-2). See page 2-19 for the jumper location.

Important notes on the RAID feature:

•By default, the drives that you connect to the ATAIDE connectors follow the ATA133/100/66/33 protocol as independent drives, not as a disk array. If you wish to configure the drives as a disk array, refer to section “5.4 RAID 0/RAID 1 configurations” on page 5-18.

•The Promise® PDC20276 RAID chipset supports RAID 0/RAID 1 for Master drives only. You may connect one Master drive in each of the ATAIDE connectors.

•When creating a disk array, use two separate ATA/133 ribbon cables to connect two Master drives to the ATAIDE connectors.

•The MBFastTrak133 Lite’s bootable BIOS supports LBA 48-bit drives over 137GB.

•The RAID chipset does not support ATAPI devices such as CD- ROMs, DVD-ROMs, etc.
