System Software Manager
System Software Manager (SSM) is a utility available on Windows—based computers that enables
you to update system-level software on multiple systems simultaneously. When executed on a PC
client system, SSM detects hardware and software versions and then updates the software from a
central repository, known as a
file store . Driver versions supported by SSM are noted with a special
icon on the software, the driver download website, and on the Support Software CD.
To download the utility or to obtain more information about SSM, see
http://www.hp.com/go/ssm.
ROM Flash
BIOS settings are stored on a programmable flash ROM. By establishing a setup password in
Computer Setup (F10) Utility, you can protect unauthorized users from modifying the BIOS settings.
This function is important to ensure the operating integrity of the computer.
To upgrade the BIOS, download the latest SoftPaq images from

workstation_swdrivers.
Remote ROM Flash
Remote ROM Flash allows system administrators to safely upgrade the ROM on remote HP
computers from a centralized network management console, resulting in a consistent deployment of,
and greater control over, HP PC ROM images over the network.
To use Remote ROM Flash, the computer must be powered on, or turned on using Remote Wakeup.
For more information about Remote ROM Flash and HPQFlash, see the HP Client Manager Software
or System Software Manager sections at
http://www.hp.com/go/ssm.
HPQFlash
The HPQFlash utility is used to locally update or restore the system ROM on PCs using a Windows
operating system. For more information about HPQFlash, see
http://www.hp.com/go/ssm, and enter
the name of the computer.
FailSafe Boot Block
The FailSafe Boot Block enables BIOS recovery in the unlikely event of a ROM flash failure. For
example, if a power failure occurs during a ROM upgrade, the Boot Block uses a flash-protected
section of the ROM to verify a valid system ROM flash when power is restored to the computer.
If the system ROM is valid, the computer starts normally.
If the system ROM fails the validation check, the FailSafe Boot Block provides enough support to start
the computer from a BIOS image CD created from a SoftPaq. The BIOS image CD programs the
system ROM with a valid image.
When Boot Block detects an invalid system ROM, the computer power LED blinks red eight times and
the computer beeps eight times; then the computer pauses for two seconds. On some models, a Boot
Block recovery mode message appears.
In preparation for system recovery, use the BIOS CD media file in the SoftPaq to create a BIOS
image CD or USB key.
