BIOS Recovery
It is unlikely that anything will interrupt the Flash upgrade process.
However, if an interruption occurs that prevents continuing with the
upgrade, it is possible the BIOS could be left in an unusable state. The steps
below tell how to recover from this kind of problem.
Note
Because of the small amount of code available in the non-
erasable boot block area, no video is available to direct the
procedure. You must monitor the flash recovery by
listening to the speaker.
1. Turn off power and remove the system cover.
2. Move the jumper to the position shown below (see Chapter 5 for the
location of the jumper block).

3. Install the bootable upgrade diskette into diskette drive A.
4. Reboot the system.
5. Listen to the speaker. You should hear beeps in the following sequence:
a) After you reboot the system, the speaker beeps once. This beep
marks the beginning of the power on self test (POST).
b) After a short delay (less than 10 seconds), the speaker beeps again,
but at a higher frequency. This marks the beginning of the recovery
process. At this point, the system is copying the recovery code into
the flash device.
c) After about 30 seconds, the speaker beeps twice (again at the higher
frequency), marking the end of the recovery process.
6. Turn the system off.
