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 a BIOS flash diskette. You can obtain a BIOS flash diskette from one of the following sources: • Use the ServerGuide program to make a BIOS flash diskette. • Download files from the World Wide Web to make a BIOS flash diskette. Go to http://www.ibm.com/pc/support/ select IBM System Support, and then make the selections for your system. • Contact your IBM service representative. Complete the following steps to recover the BIOS code: 1. When prompted, insert the BIOS flash diskette into the diskette drive. 2. Restart the server. The BIOS begins the power-on self-test. 3. The BIOS flash utility automatically starts. 4. When prompted as to whether you want to save the current code to a diskette, select N. 5. When prompted, press Y to continue the flash process. 6. The system automatically starts the flash utility a second time. 7. When prompted as to whether you want to save the current BIOS code, stop the process by removing the BIOS flash diskette from the diskette drive. 8. Restart the server, which should start up normally.

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 a BIOS flash diskette.
You can obtain a BIOS flash diskette from one of the following sources:
•
Use the ServerGuide program to make a BIOS flash diskette.
•
Download files from the World Wide Web to make a BIOS flash diskette. Go to
http://www.ibm.com/pc/support/ select IBM System Support, and then make the
selections for your system.
•
Contact your IBM service representative.
Complete the following steps to recover the BIOS code:
1.
When prompted, insert the BIOS flash diskette into the diskette drive.
2.
Restart the server. The BIOS begins the power-on self-test.
3.
The BIOS flash utility automatically starts.
4.
When prompted as to whether you want to save the current code to a diskette,
select N.
5.
When prompted, press Y to continue the flash process.
6.
The system automatically starts the flash utility a second time.
7.
When prompted as to whether you want to save the current BIOS code, stop the
process by removing the BIOS flash diskette from the diskette drive.
8.
Restart the server, which should start up normally.
