TITLE: HP Compaq Business Desktop System BIOS (786B2 BIOS)

VERSION: 2.18
DESCRIPTION:
This Softpaq contains utilities that can be used to restore or update the 
system BIOS on the HP Compaq Business Desktop models listed below with a 786B2 Family
BIOS.

NOTE: For the d530 and d538 models with existing Pentium 4 processors, this Softpaq,
BIOS Version 2.18, is a web release only and will not replace BIOS Version
1.11 in the factory. For all d330 and d338 models, and for d530 and d538 models with 
new Pentium 4 90nm technology, BIOS Version 2.18 is a new factory release that will 
be shipped on these models.

Several methods for changing the BIOS version on your computer may be chosen. 
Included in this Softpaq are the following methods: ability to create a ROMpaq 
bootable BIOS upgrade/restore floppy, ability to upgrade the BIOS directly in 
the Windows environment using HPQFlash, and the ability to create a ROMpaq 
bootable BIOS upgrade/restore CD. This Softpaq has the ability to be used with 
SSM, HPCMS, or PXE management software for remote updating of the BIOS.

The BIOS Family and BIOS date can be determined by pressing F10 on the target 
computer during system power on to run the Setup Utility, and then selecting 
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 turned on.

ENHANCEMENTS: 
  - Adds support for new Pentium 4 processor models with 90nm technology.
  - Adds support for some Japanese specific keys on USB keyboards.
  - Hyperthreading Enable/Disable in F10 BIOS Setup will remain in its current
    state when a "Set Defaults & Exit" is executed from the F10 Setup Main menu.
    This setting is preserved because it is best not to disable HT once the 
    multiprocessor version of the OS is installed.
  - Updates memory support to allow for the proper operation of 1GB PC3200 (DDR400)
    memory modules.
  - Updates the F1 help for "BIOS Wake Up" option in F10 Setup to better reflect the
    constraints of this feature. The system must be powered down from an ACPI
    compliant OS in order for this option to work. Also, this option only works when
    the system is powered off. If the system is in standby or hibernation it will not
    wake.

FIXES: 
  - Resolves potential system lockup when the F10 Setup option "Processor Cache"
    is set to Disable.
  - Resolves issue with F10 Setup Language Menu forgetting the last used
    language selection after performing a "Save Changes & Exit" command.
