Diagnostic error message tables
The tables in "Diagnostic error codes" on page 165 provide
descriptions of the error messages that might appear when
you run the diagnostic programs.
Attention:
not listed in the tables, make sure that your server has the
latest levels of BIOS, Advanced System Management
Processor, and diagnostics microcode installed.
Recovering BIOS
If your BIOS has become corrupted, such as from a power
failure during a flash update, you can recover your 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:
v Use the ServerGuide program to make a BIOS
flash diskette.
v 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 your 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:
1. Turn off the server and peripheral devices and
disconnect all external cables and power cords; then,
remove the cover.
2. Locate the boot block jumper (J37) on the system
board.
3. Place a jumper on pins 1 and 2 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.
