Note
You can obtain a BIOS flash diskette from one of the
following sources:
Ÿ
Use the ServerGuide program to make a BIOS
flash diskette.
Ÿ
Download a BIOS flash diskette from the World
Wide Web. Go to
http://www.pc.ibm.com/support/, select IBM

server.
The flash memory of your server contains a protected area
that cannot be overwritten. The recovery boot block is a
section of code in this protected area that enables the
server to start up and to read a flash diskette. The flash
utility recovers the system BIOS from the BIOS recovery
files on the diskette.
To recover the BIOS:
Before you begin:
Read “Safety information” on page 230.
1. Turn off the server and peripheral devices and
disconnect all external cables and power cords (see
“Preparing to install options” on page 100); then
remove the cover (see “Removing the left-side cover
(tower model)” on page 103 or “Removing the cover
(rack model)” on page 104).
2. Locate switch block 2 (SW2) on the system board
(see “System board component locations” on
page 166).
3. Set switch 1 on switch block 2 to ON to enable BIOS
recovery mode.
4. Insert the BIOS flash diskette into the diskette drive.
5. Restart the server.
The Recovery Boot screen will appear. A progress
report,
Loading data from diskette
xx %, is
displayed. When programming is underway, a further
progress report,

, is
displayed. When recovery is complete,
Recovery

block switch to the off position before
rebooting
.
6. Remove the flash diskette from the diskette drive.
7. Turn the server off.
8. Set switch 1 on switch block 2 (SW2) to Off to return
to normal startup mode.

normally.
