VERSION: 01.10 Rev. a
DESCRIPTION:
This package contains the System BIOS image (BIOS Family 786F5) and local and 
remote BIOS flash utilities for the HP xw8600 Workstation. These utilities can 
be used to restore or update the System BIOS. System BIOS is operating system 
independent. 

NOTE: To determine the BIOS family and BIOS date, press F10 on the target 
workstation during Power On to run the Computer Setup Utility, and then select 
File/System Information. This information can be saved into a text file on a 
diskette or on a USB flash media device by selecting File/Save to Diskette. In 
order for a USB flash media device to be recognized by the workstation, the 
device must be attached before the workstation is Powered On.

ENHANCEMENTS: 
The following enhancements have been added since BIOS version 01.07 (SP38375) 
was released:
- Adds fan control support for 8-GB memory DIMMs.
- Adds microcode and BIOS support for future processors.
- Adds a number of changes to hardware initialization sequences. These may 
further reduce rare instances of boot failure and slightly improve the 
performance of certain benchmarks.
- Adds the ability to store and retrieve any errors detected by the processor 
or chipset. 
- Increases the completion timeout value for PCI devices. This allows certain 
PCI devices to function reliably during periods of heavy system load. 

The following enhancements have been added since BIOS version 01.01 (SP37879) 
was released:
- Enables an additional CPU power saving mode in the Computer Configuration 
Utility (F10). The new mode is enabled when Idle Power Savings is set to 
"Extended."
- Adds BIOS support for additional CPU speeds.

FIXES: 
The following fixes have been made since BIOS version 01.07 (SP38375) was 
released:
- Corrects an issue that allows occasional failures to occur when entering or 
resuming from Standby (also known as Save-to-RAM or ACPI S3) state. This issue 
only occurs when running Microsoft Windows XP 32-bit version with dual 
processors installed and an audio card in slot 7.
- Fixes an issue that prevents the system from completing Power-On Self-Test 
(POST) when certain graphics cards are installed in both slots 3 and 6.
- Corrects an issue that causes certain DOS programs to fail when accessing 
serial ATA (SATA) optical storage devices while the SATA controller is in 
Advanced Host Controller Interface (AHCI) mode.
- Corrects the Multi-Processor Specification (MPS) table to properly describe 
the embedded network interface controller and x1 PCIe slot.

The following fixes have been made since BIOS version 01.01 (SP37879) was 
released:
- Adds new CPU microcode updates to resolve a processor erratum.
- Corrects an issue that could have reduced the reliability of Advanced 
Configuration and Power Interface (ACPI) save-to-RAM cycles in certain 
situations. 
- Fixes an issue that prevents the correct messages from being displayed when 
enabling Drive Lock in the Computer Configuration Utility (F10).
- Fixes an issue that prevents the maximum CPU temperature from being correctly 
reported through the Microsoft Windows Management Interface (WMI).

PREREQUISITES: 
None

INSTALLATION INSTRUCTIONS: 
This SoftPaq includes the following methods for changing the BIOS version: 
- Use HPQFlash to upgrade the BIOS directly in a Microsoft Windows XP or 
Microsoft Windows Vista environment. 
- Use the utilities in this package to flash the BIOS in a DOS environment from 
bootable media.
- Use the ROM images in this package with the Computer Setup Utility (F10) to 
flash the BIOS from a USB flash drive, diskette, or CD media.

This package can be used with System Software Manager (SSM), HP Client 
Management Solution (HPCMS), or preboot execution environment (PXE) management 
software for remote updating of the BIOS.

WARNING: DO NOT TURN OFF POWER OR ATTEMPT TO REBOOT THE COMPUTER DURING THE 
UPGRADE PROCESS!

1. Download the SoftPaq .EXE file to a directory on your hard drive.

2. Execute the downloaded file and follow the on-screen instructions to update 
the System BIOS.

NOTE: If remote flashing is required, see the remote utility documentation for 
instructions about creating a Remote ROM Flash job to flash the System ROM on 
target workstations on the network.
