Recovering from a POST/BIOS update failure
Attention: If an interruption occurs during a POST/BIOS update (flash update),
the computer might not restart correctly. If this occurs, perform the following
procedure (also known as a Boot-block recovery).
Note:
If your computer has no internal diskette drive, an optional USB diskette
drive must be connected to use the BIOS flash diskette.
1. Open the cover.
2. Remove any parts necessary to gain access to the Clear CMOS/Recovery
jumper.
3. Move the Clear CMOS/Recovery jumper from the standard position (pins 1
and 2) to pins 2 and 3.
4. Insert the BIOS flash diskette in the diskette drive.
5. Close the cover and reconnect the computer power cord to the computer and
to an electrical outlet. Turn on the computer.
6. The recovery session takes two to three minutes. During this time you will
hear a series of beeps. After the update session completes, the series of beeps
ends and the computer automatically turns off. There is no video during the
recovery session.
7. When the computer turns off, open the cover.
8. Move the Clear CMOS/Recovery jumper back to the original position (pins 1
and 2).
9. Remove the BIOS flash diskette from the diskette drive.
