11.2 BIOS Recovery Mode

The BIOS Recovery Mode permits re-flashing the BIOS when the flash ROM has been

corrupted. The sequence of events for automatic recovery is:

1. Insert recovery media and reset the system.

2. One beep indicates recovery media valid, and flash update started.

3. Approximately two minutes later, two beeps indicate flash update complete.

4. System automatically resets and starts the new BIOS.

Note: BIOS recovery requires an "El Torito" formatted CD; alternate forms of removable media

including USB devices are not supported and will result in a continuous beep code

(approximately 1 beep every 2 seconds until the system is powered down).

The BIOS Recovery Mode is initiated using the following procedure:

1. Unzip the recovery image and copy the SR870BH2.REC file onto the CD.

SR870BH2.REC should be the only file on the disk.

2. Power down the server.

3. Unplug both power cords from the server.

4. Remove the top cover from the chassis.

5. Move the jumper at J5H1 Labeled 'RCV BOOT' from pins 1-2 to pins 2-3.

6. Reconnect the AC power and switch server power on. CD Recovery activity begins.

One full beep is emitted as the server begins to load SR870BH2.REC from disk to

memory.

7. Wait two minutes. Two beeps indicate the BIOS recovery has completed successfully.

8. Remove the CD and power down the server.

9. Unplug both power cords from the server.
