Configurations

HP recommends factory configurations of the preinstalled RAID offerings for the HP Compaq dc5750

Business PCs.

The preinstalled RAID offering is a RAID 1 volume of two identical SATA hard drives, and either two SATA

80GB/8MB cache, two SATA 160GB/8MB cache, or two SATA 250GB/8MB cache drives.

NOTE: When the HP Compaq dc5750 Business PC products launch, the only supported operating system

is Microsoft Windows XP Professional Service Pack 2 (SP2). RAID Configurations are only supported with

this operating system. Hardware support is present to take advantage of the future Microsoft Vista operat-

ing system.

HP Compaq dc5750 Business PCs are based on the ATI Radeon Xpress 1 150 chipset, which is a com-

bined hardware and software RAID solution. The Radeon mass storage controller allows all drives to oper-

ate in IDE or RAID SATA modes. Each mode of the controller means a different PCI controller, with

different device ID, class code, and driver support.

NOTE: HP recommends and only supports Microsoft's IDE driver stack based on ATAPI.SYS and ATI driv-

ers for HP Compaq Business PC products, including all supported RAID configurations.
