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 support and legacy USB 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. 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
( http://h18004.www1.hp.com/products/servers/platforms/usb-support.html ).
Internal USB functionality
An internal USB connector is available for use with security key devices and USB drive keys. This solution
provides for use of a permanent USB 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, external USB functionality can be disabled through RBSU. Disabling external USB
support in RBSU disables the USB connectors on the local I/O cable. Internal USB functionality is
unaffected.
