Redundant ROM recovery

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.

When the server boots, the server detects if the current ROM is corrupt. If a corrupt ROM is detected, then the system boots from the backup ROM and sends an alert through POST that the ROM is corrupt.

To access the redundant ROM through RBSU:

  1. Power up your desktop. A prompt appears in the upper right corner of the screen.
  2. Access RBSU by pressing F9.
  3. Select Advanced Options.
  4. Select ROM Selection.
  5. Select Switch to Backup ROM.
  6. Press the Enter key.
  7. To exit the current menu, press the Esc key, or to exit RBSU, press the F10 key. The server restarts.

If RBSU is inaccessible, then you can switch ROM images by changing the switch settings on the system configuration switch. For more information, see your server documentation.

If both ROM images are corrupt, use ROMPaq recovery.
