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.
Linux BIOS Flashing
You can use the hp-flash utility and its associated driver to update the BIOS on systems running
Linux. After the driver loads, execute the utility from a command prompt with administrator privileges.
The HP ThinPro or HP Smart Client Linux OS images include the utility for updating the BIOS, but the
binary file to flash must be copied from the DOS Flash folder to the unit. Review the README.txt file
for more specific instructions in the SoftPaq. The Linux Flash folder also contains the files necessary
to build the BIOS flash driver module for the particular kernel being used; the hp-flash utility is not
kernel-dependent other than the choice of 32-bit (i686) and 64-bit (x86_64) flavors.
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
http://www.hp.com/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 more complete description of the network BIOS flashing utilities, view the DOSFlash.txt file
located in the DOS Flash folder.
BitLocker Drive Encryption / BIOS Measurements
If you have Windows BitLocker Drive Encryption (BDE) enabled on your system, we recommend that
you temporarily suspend BDE before updating the BIOS. You should also obtain your BDE recovery
password or recovery PIN before suspending BDE. After the you flash the BIOS, you can resume
BDE.
To make a change to BDE, select Start > Control Panel > BitLocker Drive Encryption, click
Suspend Protectionor Resume Protectionand then click Yes.
As a general rule, updating the BIOS will modify measurement values stored in the Platform
Configuration Registers (PCRs) of the system's security module. Temporarily disable technologies
that use these PCR values to ascertain platform health (BDE is one such example) prior to flashing
the BIOS. Once you update the BIOS, re-enable the functions and restart the system so that you can
take new measurements.
