Recovering the BIOS
It is unlikely that anything will interrupt the BIOS upgrade, however, if an interruption
occurs, the BIOS could be damaged. The following steps explain how to recover
the BIOS if an upgrade fails. For the following procedure, use the Recovery Mode
from the Setup program.
Because of the small amount of code available in the nonerasable boot block area,
there is no video support. You will not see anything on the screen during the
procedure. Monitor the procedure by listening for signals from the chassis speaker
and looking at the floppy drive activity LED.
Note
1. Turn all peripheral devices connected to the computer off. Make sure the
computer is off.
2. Remove the computer cover.

process will take a few minutes.

recovery.
