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.

1. Access RBSU by pressing the F9 key during powerup when the prompt is
