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.
5.4.1 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. From the Main menu, select IDE Configuration to display the sub-menu
items.
3. Set the IDE Configuration items as follows:
4. Press <F10> to save your changes and exit the Setup utility.
Onboard IDE Operate Mode [Enhanced Mode]
Enhanced Mode Support On [S-ATA]
Configure S-ATA as RAID [Yes]
Serial ATA BOOTROM [Enabled]
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. See path \Manual\IAA RAID Manual.doc.
When creating a RAID, make sure that the item Configure S-ATA as
RAID is set to Yes, and the item Serial ATA BOOTROM enabled, 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.
