This package contains the System BIOS image (BIOS Family 786B9) and local and remote BIOS flash utilities for the HP xw9300 Workstation. System BIOS is operating system independent. NOTE: HP xw9300 Workstations having system BIOS version 2.00 (or later), must be upgraded to NVIDIA IDE driver 553 (or later). CAUTION: Optical storage devices are the only PATA peripherals supported on the HP xw9300 Workstation. The HP xw9300 workstation does NOT support PATA hard disk drives in any RAID or non-RAID configuration. If PATA RAID is currently being used on the HP xw9300 Workstation, do NOT upgrade to system BIOS 2.00 (or later) because of potentially serious side effects. For example, the PATA RAID drive may become unbootable, resulting in loss of data.
