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.
The following procedure uses recovery mode for the Setup program. See page 33 for more
information on Setup modes.

NOTE
Because of the small amount of code available in the boot block area, there is no video support.
You will not see anything on the screen during this procedure. Monitor the procedure by listening
to the speaker and looking at the diskette drive LED.
1. Turn off the computer, disconnect the computer’s power cord, and disconnect all external
peripherals.
2. Remove the computer cover and locate the configuration jumper block (J7A1) (see Figure 14).
