Note: Use one of the following methods to obtain a BIOS flash diskette:
• Use the ServerGuide 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.
The flash memory of your server consists of a primary page and a backup page. The
J14 jumper controls which page is used to start the server. If the BIOS 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 to the primary page.
To recover the BIOS, do the following:
1. Turn off the server and peripheral devices and disconnect all power cords and
external cables; then, remove the cover.
2. Locate jumper J14 (flash ROM page swap) on the system board. See the
illustration of the system board jumper locations on page 33.
3. Move J14 to pins 1 and 2 ("lo" setting) to enable BIOS recovery mode.
4. Reconnect all external cables and power cords and turn on the peripheral devices.
5. Insert the BIOS flash diskette into the diskette drive.
6. Restart the server. The system begins the power-on self-test (POST).
7. Select 1 - Update POST/BIOS from the menu that contains various flash (update)
options.
8. When you are prompted whether you want to move the current POST/BIOS
image to the backup ROM location, press N.
Attention: If you type Y, the damaged BIOS will be copied into the secondary
page.
9. When you are prompted whether you want to save the current code to a diskette,
press N.
10. Select your language (0 through 5) and press Enter to accept your choice.
11. Attention: Do not restart the server at this time.
Remove the flash diskette from the diskette drive.
12. Turn off the server.
13. Move J14 to pins 2 and 3 ("hi" setting) to return to normal startup mode.
14. Restart the server. The system starts up.
