Safety and security benefits
When you flash the system ROM, ROMPaq writes over the backup ROM and saves the current ROM as a
backup, enabling you to switch easily to the alternate ROM version if the new ROM becomes corrupted for
any reason. This feature protects the existing ROM version, even if you experience a power failure while
flashing the ROM.
USB support and functionality
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
Internal USB functionality
An internal USB connector is available for use with USB drive keys only. This solution provides for use of a
permanent boot drive from a USB drive key installed in the internal connector, avoiding issues of clearance
on the front of the rack and physical access to secure data.
For additional security, you can disable the external USB connectors through RBSU. Disabling the rear USB
connectors in RBSU disables both rear USB ports.
External USB functionality
HP provides external USB support to enable local connection of USB devices for server administration,
configuration, and diagnostic procedures.
For additional security, external USB functionality can be disabled through RBSU.
Diagnostic tools
HP Insight Diagnostics
HP Insight Diagnostics is a proactive server management tool, available in both offline and online versions,
that provides diagnostics and troubleshooting capabilities to assist IT administrators who verify server
installations, troubleshoot problems, and perform repair validation.
HP Insight Diagnostics Offline Edition performs various in-depth system and component testing while the OS
is not running. To run this utility, launch the SmartStart CD.
