Redundant ROM support

The server blade enables you to upgrade or configure the ROM safely with redundant ROM support. The
server blade 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:
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:
The server blade includes new hardware that may not have driver support on all OS installation media.
If you are installing an Intelligent Provisioning-supported OS, use Intelligent Provisioning (on page 53) and its
Configure and Install feature to install the OS and latest supported drivers.
If you do not use Intelligent Provisioning to install an OS, drivers for some of the new hardware are required.
These drivers, as well as other option drivers, ROM images, and value-add software can be downloaded as
part of an SPP.
If you are installing drivers from SPP, be sure that you are using the latest SPP version that your server blade
supports. To verify that your server blade is using the latest supported version and for more information about
SPP, see the HP website (http://www.hp.com/go/spp/download).
To directly locate the OS drivers for a particular server blade, enter the following web address into the
browser:
http://www.hp.com/support/<servername>
In place of <servername>, enter the server name.
For example:
http://www.hp.com/support/dl360g6
The server ships with the same version programmed on each side of the ROM.
Always perform a backup before installing or updating device drivers.
