Updating BIOS code
You can download the latest BIOS code from http://www.ibm.com/pc/support/. Use
this code to create a POST/BIOS flash diskette.
Complete the following steps to update the BIOS code on the computer:
1. Insert the POST/BIOS flash diskette into drive A.
2. Turn on or restart the computer (see “Turning off the computer” on page 10 for
instructions). The computer starts from the diskette.
3. When you are prompted to save the current code to a diskette, select N. The
utility will continue to the next step. If you select Y, you are asked to name the
file to be saved, and the file is saved to the diskette.
4. When prompted to continue the POST/BIOS flash update, select Y. The flash
ROM is updated with the new code. When this step is complete, the computer
automatically restarts.
