ROMPaq utility
The ROMPaq utility enables you to upgrade the system firmware (BIOS). To upgrade the firmware, insert a
ROMPaq USB Key into an available USB port and boot the system. In addition to ROMPaq, Online Flash
Components for Windows and Linux operating systems are available for updating the system firmware.
The ROMPaq utility checks the system and provides a choice (if more than one exists) of available firmware
revisions.
For more information, go to the HP website (http://www.hp.com/go/hpsc) and click on Drivers, Software
& Firmware. Then, enter your product name in the Find an HP product field and click Go.
Automatic Server Recovery
ASR is a feature that causes the system to restart when a catastrophic operating system error occurs, such as
a blue screen, ABEND (does not apply to HP ProLiant DL980 Servers), or panic. A system fail-safe timer, the
ASR timer, starts when the System Management driver, also known as the Health Driver, is loaded. When the
operating system is functioning properly, the system periodically resets the timer. However, when the
operating system fails, the timer expires and restarts the server.
ASR increases server availability by restarting the server within a specified time after a system hang. At the
same time, the HP SIM console notifies you by sending a message to a designated pager number that ASR
has restarted the system. You can disable ASR from the System Management Homepage or through RBSU.
USB support
HP provides both standard USB 2.0 support and legacy USB 2.0 support. Standard support is provided by
the OS through the appropriate USB device drivers. Before the OS loads, HP provides support for USB
devices through legacy USB support, which is enabled by default in the system ROM.
Legacy USB support provides USB functionality in environments where USB support is not available normally.
Specifically, HP provides legacy USB functionality for the following:
• POST
• RBSU
• Diagnostics
• DOS
• Operating environments which do not provide native USB support
Redundant ROM support
The server enables you to upgrade or configure the ROM safely with redundant ROM support. The server has
a single ROM that acts as two separate ROM images. In the standard implementation, one side of the ROM
contains the current ROM program version, while the other side of the ROM contains a backup version.
