Recovering The Bios - Intel D815EEA2 - Desktop Board Motherboard Product Manual

Recovering the BIOS

It is unlikely that anything will interrupt the BIOS update, however, if an interruption occurs, the
BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails.
The following procedure uses recovery mode for the Setup program. See page 48 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 (J9G2) (see Figure 26).
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.

4. Insert the bootable BIOS update diskette into diskette drive A.
5. Replace the computer cover, connect the power cord, turn on the computer, and allow it to
boot. (The recovery process will take a few minutes. Listen to the speaker and watch for
drive A activity.)
•
Upon applying power, drive A will begin to show activity. In about a minute, two beeps
are heard and drive A activity ceases (temporarily) indicating the successful recovery of
the BIOS core. Drive A activity will begin again followed by two more beeps indicating
the successful recovery of the boot block. This sequence of events indicates that
successful BIOS recovery has taken place.
•
A series of continuous beeps indicates that BIOS recovery has failed.
6. If recovery fails, return to step 1 and repeat the recovery process.
7. If recovery is successful, turn off the computer, and disconnect its power cord.
8. Remove the computer cover and continue with the following steps.
9. On the jumper block (J9G2), reinstall the jumper back on pins 1-2 as shown below to set
normal mode for Setup.
