TITLE: HP Compaq Business Desktop System BIOS (786C1 BIOS)

VERSION: 01.57 Rev. A
DESCRIPTION:
This package contains utilities that can be used to restore or update the 
system BIOS on the listed desktop models with a 786C1 BIOS.

Several methods for changing the BIOS version may be chosen. Included in this 
package are the following methods:
- Create a ROMpaq bootable BIOS upgrade/restore diskette.
- Use HPQFlash to upgrade the BIOS directly in a Microsoft Windows 
environment.
- Create a ROMpaq bootable BIOS upgrade/restore CD.

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

NOTE: To determine the BIOS family and BIOS date, press F10 on the target 
computer during system Power On to run the 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 system, the device 
must be attached before the computer is Powered On.

NOTE: For HP Compaq Business Desktop dc7100 Convertible Minitower and HP Compaq 
Business Desktop dc7100 Small Form Factor models, this SoftPaq, BIOS Version 
1.57, is a web and factory release. It will replace BIOS Version 1.05 in the 
factory only for PCI Express NVIDIA Quatro 280NVS 64 MFH models. 

For HP Compaq Business Desktop dx6100 Microtower and HP Compaq Business Desktop 
dx6100 Slimtower models, BIOS Version 1.57 is a new factory release that will 
be shipped on new models, replacing BIOS version 1.06 in the factory.

DO NOT REPLACE the BIOS for HP Compaq Business Desktop dc7100 Ultra-Slim 
Desktop models, because this SoftPaq contains an earlier version of the BIOS 
(version 1.57) than the initial BIOS (version 1.59) shipping on this model.
