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 node enables you to upgrade or configure the ROM safely with redundant ROM support. The node 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.
NOTE:
The server ships with the same version programmed on each side of the ROM.
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.
Keeping the system current
Drivers
IMPORTANT:
Always perform a backup before installing or updating device drivers.
The node includes new hardware that may not have driver support on all OS installation media.
Drivers, ROM images, and value-add software can be downloaded as part of an SPP ("
" on page
). If you are installing drivers from SPP, be sure that you are using the latest SPP version
that your node supports. To verify that your node is using the latest supported version and for more
information about SPP, see the HP website
To locate the drivers for a particular node, go to the HP website
and click on
Drivers, Software & Firmware. Then, enter your product name in the Find an HP product field and click Go.
