IBM xSeries 135: User's Reference
If the BIOS has become damaged, such as from a power failure during a flash update,
you can recover the BIOS using the BIOS code page jumper and a BIOS flash diskette.
Note: You can obtain a BIOS flash diskette from one of the following sources:
• Use the BIOS flash program to make a BIOS flash diskette.
• 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.
• Contact your IBM service representative.
To recover the BIOS:
1. Turn off the server and peripheral devices and disconnect all external cables and
power cords; then, remove the cover.
2. Locate the BIOS code page jumper (J19) on the system board.
3. Place a jumper on pins 1 and 2 to enable the BIOS back page.
Note: Before continuing, refer to "Working inside a server with power on" on
page 38.
4. Reconnect all external cables and power cords and turn on the peripheral devices.
5. Insert the BIOS flash diskette in the diskette drive.
6. Restart the server. The system begins the power-on self-test (POST) and BIOS
flash.
