Recovering from a BIOS update failure
The blade server has an advanced recovery feature that will automatically switch to
a backup BIOS page if the BIOS code in the blade server has become damaged,
such as from a power failure during an update.
The flash memory of the blade server consists of a primary page and a backup
page. If the BIOS code in the primary page is damaged, the baseboard
management controller will detect the error and automatically switch to the backup
page to start the blade server. If this happens, a POST message Booted from
backup POST/BIOS image is displayed. The backup page version may not be the
same version as the primary image.
You can then recover or restore the original primary page BIOS by using a BIOS
flash diskette.
To recover the BIOS code and restore the blade server operation to the primary
page, complete the following steps:
1. Download the latest version of the BIOS code from http://www.ibm.com/systems/
2. Update the BIOS code, following the instructions that come with the update file
3. Restart the blade server.
If that procedure fails, the blade server might not restart correctly or might not
display video. To manually restore the BIOS code, complete the following steps:
