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.
Access to redundant ROM settings
To access the redundant ROM through RBSU:
1.
Access RBSU by pressing the F9 key during powerup when the prompt is displayed in the upper
right corner of the screen.
2.
Select Advanced Options.
3.
Select Redundant ROM Selection.
4.
Select the ROM version.
5.
Press the Enter key.
6.
Press the Esc key to exit the current menu or press the F10 key to exit RBSU. The server restarts
automatically.
To access the redundant ROM manually:
1.
Power down the server (on page
2.
Remove the access panel (on page
3.
Set positions 1, 5, and 6 of the system maintenance switch to On.
4.

5.
Power up the server (on page
6.
Wait for the server to emit two beeps.
7.
Repeat steps 1 and 2.
8.
Set positions 1, 5, and 6 of the system maintenance switch to Off.
9.
Repeat steps 4 and 5.
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 prior
to the operating system loading through legacy USB support, which is enabled by default in the system
ROM. HP hardware supports USB version 2.0.
Legacy USB support provides USB functionality in environments where USB support is normally not
available. Specifically, HP provides legacy USB functionality at:
•
POST
•
RBSU
•
Diagnostics
•
DOS
•
Environments which do not support USB natively
