When the server boots, the system identifies whether the current ROM bank is corrupt. If a corrupt ROM is
detected, the system boots from the backup ROM and alerts you through POST or IML that the ROM bank
is corrupt.
If both the current and backup versions of the ROM are corrupt, the server automatically enters ROMPaq
disaster recovery mode.
USB support
HP provides both standard USB support and legacy USB support. Standard support is provided by the
operating system through the appropriate USB device drivers. HP provides support for USB devices before
the operating system loads through legacy USB support, which is enabled by default in the system ROM.
HP hardware supports USB version 1.1 or 2.0, depending on the version of the hardware.
Legacy USB support provides USB functionality in environments where USB support is normally not
available. Specifically, HP provides legacy USB functionality for:
• POST
• RBSU
• Diagnostics
• DOS
• Operating environments which do not provide native USB support
For more information on ProLiant USB support, refer to the HP website

Diagnostic tools
Array Diagnostic Utility
The HP Array Diagnostics Utility is a web-based application that creates a report of all HP storage
controllers and disk drives. This report provides vital information to assist in identifying faults or conditions
that may require attention. ADU can be accessed from the SmartStart CD ("SmartStart software" on page
67) or downloaded from the HP website (http://www.hp.com
).
