Recovering the BIOS code
If the BIOS code has become damaged, such as from a power failure during a flash
update, you can recover the BIOS code using the boot block jumper and a BIOS
flash diskette.
Note: You can obtain a BIOS flash diskette from one of the following sources:
v
Use the ServerGuide Setup and Installation CD to make a BIOS flash
diskette.
v Download a BIOS flash diskette from the World Wide Web. Go to
http://www.ibm.com/pc/support, click
IBM Server Support , and make the
selections for your server.
v Contact your IBM service representative.
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 code from the BIOS recovery files on the diskette.
