To recover the BIOS, do this:
1.
Remove the CPU module from slot CPU 1.
2.
Move the jumper to pins 2 and 3 to enter the recovery mode.
3.
Ensure that Switch S8C1-3 is in the ON position.
4.
Replace the side panel and CPU module and insert the flash
memory update diskette in drive A.
5.
Connect the power cord to the system and turn it on. After the
system boots successfully, the speaker emits a single beep and the
recovery process starts; it takes about three minutes. When the
recovery process completes, the system speaker emits two beeps.
While in the recovery mode, there is no screen display on the
monitor, and the keyboard is disabled as the system automatically
recovers the BIOS. The recovery status is identified through beep
codes, given in the following table:
Beep Code
2
4
Continuous series
of low beeps

from slot CPU 1.
6.

mode.
7.

memory update diskette from drive A.

new password. For information on running the SCU, see Chapter 2,
Operating Your System.
