•
Auto (default) —If configured in Auto Mode, USB 3.0 capable devices operate at USB 2.0 speeds in the
pre-boot environment and during boot. When a USB 3.0 capable OS USB driver loads, USB 3.0
devices transition to USB 3.0 speeds. This mode provides compatibility with operating systems that do
not support USB 3.0 while still allowing USB 3.0 devices to operate at USB 3.0 speeds with state-of-the
art operating systems.
•
Enabled —If Enabled, USB 3.0 capable devices operate at USB 3.0 speeds at all times (including the
pre-boot environment) when in UEFI Boot Mode. This mode should not be used with operating systems
that do not support USB 3.0. If operating in Legacy Boot BIOS Mode, the USB 3.0 ports cannot function
in the pre-boot environment and are not bootable.
•
Disabled —If configured for Disabled, USB 3.0 capable devices function at USB 2.0 speeds at all times.
The pre-OS behavior of the USB ports is configurable in System Utilities, so that the user can change the
default operation of the USB ports. For more information, see the
HP UEFI System Utilities User Guide for HP
ProLiant Gen9 Servers on the HP website ( http://www.hp.com/go/ProLiantUEFI/docs ).
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: 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
