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 during the PowerOn 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: BIOS item SATA Mode On-Chip Serial ATA Serial ATA Port0 Mode Serial ATA Port1 Mode A [RAID] [Combined Mode] [Primary Master] [Primary Slave] B [RAID] [Enhanced Mode] [SATA0 Master] [SATA1 Master] C [RAID] [SATA Only] [Primary Master] [Secondary Master] 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. 4. Press to save your changes, then press 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. 5-18 Chapter 5: Driver installation
