NOTE: The following notes are important for RAID configuration. • RAID 1 is the only RAID configuration that HP Compaq dc5850 Business PC products offer as factory configurations. • The preconfigured systems: - Are complete RAID systems. - Have both drives installed. - Have the necessary Option ROM configuration. - Are preloaded and preinstalled with all required software. - Include a preinstalled operating system that is in mirrored mode out of the box. Single Drive AHCI Configuration To take advantage of single drive AHCI support, a change is required in F10 setup. To run a single drive configuration in AHCI mode: 1. Turn on or restart the computer by clicking Start > Shut Down > Restart the Computer. 2. Press F10 as soon as the monitor light turns green. If you do not press F10 at the appropriate time, you must restart the computer, and then press F10 again to access the utility. 3. Select your language from the list, and then press Enter. 4. Use the arrow keys to select Storage. 5. Use the down arrow key to select Storage Options, and then press Enter. 6. Change SATA Emulation from IDE to AHCI RAID. NOTE: Make sure the AMD RAID driver is loaded in the SW image prior to making the F10 setup change. The operating system will not boot without this driver. The dc5850 factory SW image already contains this driver. This driver is also provided as a softpaq at www.hp.com. Basic RAID Types This section provides a brief explanation of the supported RAID configurations for HP Compaq dc5850 Business PCs. RAID 0 with two hard drives (Striped) Even though HP supports RAID 0, it is not the recommended configuration for business PC users. Lack of redundancy causes less than half the reliability of a single hard drive system since the Mean Time Between Failure (MTBF) of RAID 0 is equal to the MTBF of an individual drive, divided by the number of drives. 4
