Redundant ROM support
The server enables you to upgrade or configure the ROM safely with redundant ROM support. The server
has a 4-MB ROM that acts as two, separate 2-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 support and legacy USB 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. HP hardware supports USB
version 1.1 or 2.0, depending on the version of the hardware.
Legacy USB support provides USB functionality in environments where USB support is normally not
available. Specifically, HP provides legacy USB functionality for:
•
POST
•
RBSU
•
Diagnostics
•
DOS
•
Operating environments which do not provide native USB support
