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.
