A BIOS upgrade option is available through both the Startup Menu and the F10 Setup utility using the
"Flash System ROM" feature.
1. Reboot the computer and press the
2. Use the arrow keys to select Utilities, and then select the Flash System ROM option.
1. Alternatively, reboot the PC and press
2. In the File menu, select Flash System ROM.
Either method requires that removable media be present that contains the BIOS binary image file in the
root directory. You can find the binary image file in the DOS Flash folder. The image is named
xxx_MMmm.bin, where "xxx" is the BIOS family, "MM" is the major version number, and "mm" is the
minor version number. To create a CD for updating the BIOS, use a blank CD-R or CD-RW disk on a
system with a CD-RW or DVD+RW drive, and write the binary to the disk using any CD-burning
software. If a BIOS Setup password is set, the password is required before you can access the Flash
System ROM menu. You are notified when the process completes. The new BIOS code will not take
effect until you restart the PC.
USB Device BIOS Flashing in DOS
DOS Flash (DOSFlash.exe, FlshUefi.cpu) is the DOS-compatible System BIOS flash utility that you can
use from a DOS bootable storage device (where "DOS" refers to any of a number of compatible
operating systems such as FreeDOS, MS-DOS or DR-DOS). FlshUefi.cpu is the required driver for
DOSFlash.exe. To flash the System BIOS from a bootable USB storage device, copy the contents of the
DOS Flash folder to the USB device, boot the computer from the USB device, and execute the
DOSFlash application.
To see a more complete description of the DOS flash utilities, view DOSFlash.txt located in the DOS
Flash folder of the SoftPaq. This folder also contains the required binary image of the BIOS. The binary
image file is named xxx_MMmm.bin where "xxx" is the BIOS family, "MM" is the major version
number, and "mm" is the minor version number. You can copy this file to the root directory of any USB
removable medium for use with the F10 setup "Flash System ROM" option or BootBlock Emergency
Recovery Mode.
System Software Management (SSM) BIOS Flashing
Use this SoftPaq with System Software Manager (SSM) to update the System BIOS on target computers
on a network. Place this SoftPaq in your SSM Filestore folder and then update the database. SSM is a
free utility provided by Hewlett-Packard Company. For information on SSM, see
go/ssm.
HP Client Manager Software (HPCMS) BIOS Flashing
Use this Softpaq with HP Client Manager Software (HPCMS) and Altiris Notification Server to remotely
target, distribute, and update the System BIOS on network PCs. Place this SoftPaq in your HPCMS
Filestore folder and then update the database. HPCMS is a free managment application provided by
Altiris and Hewlett-Packard Company. For more information, see http://www.hp.com/go/EasyDeploy.
Network BIOS Flashing
We designed the DOS Flash utility to support System BIOS flashing from a remote network boot using
PXE. DOS Flash uses a small memory footprint that is compatible with the limited DOS memory
available and the DOS extended environment that may exist while running Altiris eXpress. To see a
