troller allows all drives to operate 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 the ATAPI.SYS driver for HP Compaq Business PC products including all supported RAID configurations. WARNING: The PCI Device ID of the mass storage controller changes after changing IDE mode. Changing the BIOS from IDE mode to RAID mode is the equivalent of connecting the hard drives to a new addon RAID storage controller. The installed operating system on the hard drive is unaware of this new mass storage controller. If the operating system does not have the RAID drivers enumerated and PnP for the RAID controller, the operating system will fail to boot (blue screens) when Microsoft XP Professional (SP2) attempts to boot. HP Backup and Recovery interactions After enabling and configuring RAID, restore the system using backup CDs. After completing the restore, reinstall HP Backup and Recovery. These steps are necessary for the F11 restore to function properly. HP also recommends keeping the default options in the RAID Option ROM and in the Windows RAID application. Options like "chunk" size for changing the size "stripe" size have more history in their defaults settings. Additional technical information will be provided in the future for customers who want to add RAID software image deployment capabilities. Other supported configurations The HP Compaq dc7700 and dx7300 Business PC products support two other RAID configurations: • Two hard drive configuration. • Two equal size/type SATA hard drive RAID configurations in RAID 0 or RAID 1 or Matrix Mode of RAID 0 and RAID 1. • Maximum of two SATA optical drives (on HP Compaq dc7700 Business PC Convertible Minitower or HP Compaq dx7300 Business PC Microtower). • Three hard drive configuration (only on HP Compaq dc7700 Business PC Convertible Minitower or HP Compaq dx7300 Business PC Microtower). • Three equal size/type SATA hard drive RAID configurations in RAID 0 or RAID 5 or Matrix Mode of RAID and RAID 5. • Maximum of one SATA optical drives. Unsupported configurations The HP Compaq dc7700 and dx7300 Business Desktop PC products only support the best user experience and highest possible reliability. As a result, HP does not support the following combinations of RAID hard drives: • Different sizes • Different speeds (5400 rpm, 7200 rpm, etc) 12

troller allows all drives to operate in IDE or RAID SATA modes. Each mode of the controller means a dif-
ferent PCI controller, with different device ID, class code, and driver support.
NOTE
: HP recommends and only supports Microsoft’s IDE driver stack based on the ATAPI.SYS driver for
HP Compaq Business PC products including all supported RAID configurations.
WARNING:
The PCI Device ID of the mass storage controller changes after changing IDE mode. Chang-
ing the BIOS from IDE mode to RAID mode is the equivalent of connecting the hard drives to a new add-
on RAID storage controller. The installed operating system on the hard drive is unaware of this new mass
storage controller. If the operating system does not have the RAID drivers enumerated and PnP for the
RAID controller, the operating system will fail to boot (blue screens) when Microsoft XP Professional (SP2)
attempts to boot.
HP Backup and Recovery interactions
After enabling and configuring RAID, restore the system using backup CDs. After completing the restore,
reinstall HP Backup and Recovery. These steps are necessary for the F11 restore to function properly.
HP also recommends keeping the default options in the RAID Option ROM and in the Windows RAID
application. Options like “chunk” size for changing the size “stripe” size have more history in their
defaults settings.
Additional technical information will be provided in the future for customers who want to add RAID soft-
ware image deployment capabilities.
Other supported configurations
The HP Compaq dc7700 and dx7300 Business PC products support two other RAID configurations:
•
Two hard drive configuration.
•
Two equal size/type SATA hard drive RAID configurations in RAID 0 or RAID 1 or Matrix
Mode of RAID 0 and RAID 1.
•
Maximum of two SATA optical drives (on HP Compaq dc7700 Business PC Convertible Mini-
tower or HP Compaq dx7300 Business PC Microtower).
•
Three hard drive configuration (only on HP Compaq dc7700 Business PC Convertible Minitower or
HP Compaq dx7300 Business PC Microtower).
•
Three equal size/type SATA hard drive RAID configurations in RAID 0 or RAID 5 or Matrix
Mode of RAID and RAID 5.
•
Maximum of one SATA optical drives.
Unsupported configurations
The HP Compaq dc7700 and dx7300 Business Desktop PC products only support the best user experi-
ence and highest possible reliability. As a result, HP does not support the following combinations of RAID
hard drives:
•
Different sizes
•
Different speeds (5400 rpm, 7200 rpm, etc)
