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.
1Turn off all connected peripherals, turn off system power, and disconnect the AC power cord.
2Remove the access cover and expose the server board. For instructions, see the product guide accompanying your chassis.
3Move the Recovery Boot (RCVRY BOOT) jumper from its normal position to the BIOS recovery position (see “Server Board Jumpers” on page 97).
4Reinstall the access cover and connect the power cord.
5Insert the diskette holding the BIOS upgrade and recovery files into drive A.
6Turn on system power and listen to the speaker:
•Two beeps indicate successful BIOS
•A series of continuous beeps indicates failed BIOS recovery- Return to Step 1 and repeat the recovery process.
7Turn off system power and disconnect all AC power cords.
8Remove the access cover.
9Move the Recovery Boot jumper back to its normal position.
10Reinstall the access cover.
