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 workstation blade enables you to upgrade or configure the ROM safely with redundant ROM support.
The workstation 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: 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 workstation 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
70 ) 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.
