PREREQUISITES: N/A

FIXES:
- Adds new VBIOS Version 3241 to resolve a DVI issue that can occur during startup
with dual monitors when using a DVI add-in card and the internal graphics controller.
- Resolves potential system lockup when the F10 Setup option "Processor Cache"
is set to Disable.
- Resolves issue where F10 Setup Language Menu did not preserve the last used
language selection after performing a "Save Changes & Exit" command.
- Updates memory support to allow for the proper operation of 1-GB PC3200
(DDR400) memory modules.
- Resolves issue with some PCI - Cardbus bridge cards not loading the "Generic
Cardbus Controller," which resulted in the driver for the controller having
an error condition in Windows XP.
- Corrects an issue with USB 2.0 devices being visible in the OS when connected
to the front USB ports even though the front USB ports have been disabled or
hidden in F10 Setup.
- Corrects BIOS F10 Setup's Italian Storage Menu for Hard Drives, which was not
displaying the complete text.
- Updates PXE ROM to version 6.3.0. This ROM fixed a PXE boot failure that
occurred with some PXE servers where the "DHCP boot filename" option (OPTION
67) was manually added. Also the base code was fixed so that the provided
length field file name strings are used to nullify the filename that is used
for TFTP/MTFTP download.

ENHANCEMENTS:
- Adds support for some Japanese specific keys on USB keyboards.
- Adds support for USB CD-ROM boot. The CD-ROM drive must support this
functionality in order for this to work correctly.
- Adds a new F10 Setup feature that allows the user the ability to adjust the minimum
fan speed to higher values. The fan controller still works normally and will
adjust the fans to higher speeds if required by temperature. The behavior of
the fan is identical to previous BIOS versions, unless the user changes this
new F10 Setup feature.
- Hyperthreading Enable/Disable in F10 BIOS Setup will remain in its current
state when a "Set Defaults & Exit" is executed from the F10 BIOS Setup\Main
menu. This setting is preserved because it is best not to disable HT once the
multiprocessor version of the OS is installed.
- Adds code to ensure the SATA 1 device DMA capabilities reported to the
operating system reflect the currently selected data transfer mode when "SATA
Configuration" is set to "Replace Primary IDE Controller" in F10 Setup.
- Installs the latest microcode updates for the F24, F27, and F29 processor
steppings of the Intel Pentium IV processor. The processor stepping can be
determined by accessing the System Information selection from the File menu of
F10 BIOS Setup.
- Adds support for soft power-down in Windows NT 4.0. This change works in
conjunction with the "Compaq Power Management Extensions for Windows NT 4.0"
software that is located at www.hp.com.
- Adds F10 Setup menu for "BIOS Wakeup" option. This option allows the user to
set up a specific time and the days that the system will wake up from the soft
off state (S5 sleep state).
- 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 with this feature.
- Adds additional text to better describe consequences if security device reset,
for the TPM, is selected.
- Adds F10 Setup options for disabling/enabling each IDE (PATA) channel.
