Redundant Rom Support; Keeping The System Current; Drivers - HP ProLiant DL360 Gen9 User Manual

Before the OS loads, HP provides support for USB 2.0 devices through legacy USB support, which is enabled
by default in the system ROM. USB 3.0 ports are not functional before the OS loads. The native OS provides
USB 3.0 support through appropriate xHCI drivers.
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 (system boot)
•
UEFI System Utilities
•
Pre-boot UEFI shell
•
DOS
•
Operating environments which do not provide native USB support
External USB functionality
HP provides external USB support to enable local connection of USB devices for server administration,
configuration, and diagnostic procedures.
For additional security, external USB functionality can be disabled through USB options in UEFI System
Utilities.

Redundant ROM support

The server enables you to upgrade or configure the ROM safely with redundant ROM support. The server 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 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 94) and its
Configure and Install feature to install the OS and latest supported drivers.
The server ships with the same version programmed on each side of the ROM.
Always perform a backup before installing or updating device drivers.
