If the BIOS 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:
http://www.pc.ibm.com/support/ - select IBM Server Support,
and make the selections for the server.
The flash memory of the 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 automatically recovers the system BIOS from the BIOS recovery files on the diskette.
To recover the BIOS:
Nothing appears on the display monitor, but the diskette drive activity LED and periodic beeps indicates that BIOS recovery is under way. Recovery is complete when slow beeps are concluded by a string of fast beeps and the Post Complete light on the operator LED panel is on.
