Recovering the BIOS

It is unlikely that anything will interrupt the BIOS upgrade; however, 
an interruption could damage the BIOS. The following steps explain 
how to recover the BIOS if an upgrade fails. The following procedure 
uses recovery mode for the Setup program.

Note: Because of the small amount of code available in the non-
erasable boot block area, there is no video support. You will not 
see anything on the screen during the procedure. Monitor the 
procedure by listening to the speaker and looking at the floppy 
drive LED.

1

Turn off all connected peripherals, turn off system power, and 
disconnect the AC power cord.

2

Remove the access cover and expose the server board. For 
instructions, see the product guide accompanying your chassis.

3

Move the Recovery Boot (RCVRY BOOT) jumper from its normal 
position to the BIOS recovery position (see “Server Board Jumpers” 
on page 97).

4

Reinstall the access cover and connect the power cord.

5

Insert the diskette holding the BIOS upgrade and recovery files 
into drive A.

6

Turn on system power and listen to the speaker:

•

Two beeps indicate successful BIOS recovery-Go to the next 
step.

•

A series of continuous beeps indicates failed BIOS recovery-
Return to Step 1 and repeat the recovery process.
