power on (see "Minimum operating requirements" on
page 187).
4. Reconnect the AC cord and power on the system. If
the system powers up successfully, replace adapters
and devices one at a time until the problem is isolated.
If system does not power up from minimal configura-
tion, replace FRUs of minimal configuration one at a
time until the problem is isolated.
To use this method it is important to know the minimum con-
figuration required for a system to power up (see page 187).
For specific problems, see "Power error messages" on page
183.

Recovering BIOS

If the BIOS code in the server has become corrupted, such
as from a power failure during a flash update, you can
recover the BIOS using the recovery boot block and a BIOS
flash diskette.
Note: You can obtain a BIOS flash diskette from one of the
following sources:
• Use the ServerGuide program to make a BIOS
flash diskette.
• Download a BIOS flash diskette from the World
Wide Web. Go to
http://www.pc.ibm.com/support/, select IBM
Server Support, and make the selections for the
server.
The flash memory of the server consists of a primary page
and a backup page. The J14 jumper controls which page is
used to start the server. If the BIOS in the primary page is
corrupted, you can use the backup page to start the server;
then boot the BIOS Flash Diskette to restore the BIOS to the
primary page.
To recover the BIOS:
1. Turn off the server and peripheral devices and
disconnect all external cables and power cords; then,
remove the cover.
2. Locate jumper J14 on the processor board (see
"System board jumpers" on page 56).
3. Move J14 to pins 1 and 2 to enable secondary boot
block page.
4. Insert the BIOS flash diskette into the diskette drive.
5. Restart the server.
6. The system begins the power-on self-test (POST).
Select 1 – Update POST/BIOS from the menu that con-
tains various flash (update) options.
7. When you are asked if you would like to move the cur-
rent POST/BIOS image to the backup ROM location,
type N.
Attention: Typing Y will copy the corrupted BIOS into
the secondary page.
