Recovering BIOS code If the BIOS code in the server has become damaged, 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. You can download a BIOS flash diskette from http://www.ibm.com/pc/support/. The flash memory of the server consists of a primary page and a backup page. The J19 jumper on the I/O board controls which page is used to start the server. If the BIOS code in the primary page is damaged, you can use the backup page to start the server; then start the BIOS flash diskette to restore the BIOS code to the primary page. To recover the BIOS code, complete the following steps: 1. Read "Safety information" on page 147 and "Handling static-sensitive devices" on page 30. 2.
