5.5 Intel ® RAID for Serial ATA
The Intel ® ICH5R chipset supports Redundant Array of Independent Disks
(RAID) configuration. Using two Serial ATA hard disks on SATA1 and
SATA2 connectors onboard, you may set up a RAID 0 level storage
configuration.
RAID 0 (called data striping) optimizes two identical hard disk drives to
read and write data in parallel, interleaved stacks. Two hard disks perform
the same work as a single drive but at a sustained data transfer rate,
double that of a single disk alone, thus improving data access and
storage.
5.5.1 BIOS configuration
Follow these steps to set the BIOS items related to the RAID function.
1. Enter the BIOS Setup utility by pressing <Delete> during the Power-
On Self Test (POST). See section “4.2 BIOS Setup program” for
more information on entering the Setup utility.
2. Select Advanced > Integrated Peripherals > OnChip IDE Device
3. Set the SATA items to either one of the following options:
4. Press <F10> to save your changes, then press <Esc> to exit the
Setup utility.
For more information on the Intel RAID for Serial ATA , refer to the Intel
Application Accelerator (RAID Edition) User’s Manual in the
motherboard support CD.
When creating a RAID, make sure that the item SATA Mode is set to
RAID to load the Intel RAID Option ROM upon boot up. The Intel RAID
Option ROM provides the pre-operating system user interface for the
Intel RAID implementation.
