Redundant ROM support
The server enables you to upgrade or configure the ROM safely with redundant ROM support. The server has
an 8-MB ROM that acts as two, separate 4-MB ROMs. 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.
USB support and functionality
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
Internal USB functionality
An internal USB connector is available for use with USB drive keys only. This solution provides for use of a
permanent boot drive from a USB drive key installed in the internal connector, avoiding issues of clearance
on the front of the rack and physical access to secure data.
For additional security, you can disable the external USB connectors through RBSU. Disabling the rear USB
connectors in RBSU disables both rear USB ports.
