Enable RAID Function
For any RAID controller, the general procedure to setup a RAID system is shown
below:
Step 1: Create RAID Array
RAID arrays are created using the RAID controller’s BIOS utility.
For Intel ICH6R
1. Under CMOS setup, Integrated Peripherals section, set “SATA mode” to
RAID, set “Intel RAID Boot ROM” to Enabled and restart the system.
2. Power-on the system and wait for the RAID BIOS Setting utility message on
the screen. Press the ”CTRL-I” key to enter its BIOS configuration utility.
3. Refer to Appendix B for details about creating RAID array using this utility.
4. After the RAID array is created, press “Esc” to exit.
Note: If you are not installing O/S into the RAID
disks, you may skip Step 2 & Step3.
