To recover the BIOS:

1Turn off the system and disconnect the power cord, modem cord (if installed), and all external peripheral devices.

2Open the case (see “Opening the case” on page 17), observing the “Static electricity precautions” on page 15.

3Remove the jumper from the J5K1 (see “System board” on page 5) and set it aside. You will need it in a later step.

4Close the case (see “Closing the case” on page 19), then reconnect the power cords.

5Place the bootable diskette containing the BIOS files into drive A:, then turn on the computer.

At the start of the BIOS recovery process, the computer beeps once. The recovery process may take a few minutes.

6When you hear two beeps, the BIOS has been successfully recovered. Remove the diskette from drive A:, turn off the computer, and disconnect the power cord.

If you do not hear two beeps, the BIOS recovery was not successful. See the troubleshooting section at the end of this procedure for further information.

7Open the case again (see “Opening the case” on page 17), observing the “Static electricity precautions” on page 15.

8Place the jumper back on pins 1-2 on the J5K1 jumper.

9Close the case (see “Closing the case” on page 19), then reconnect the power cords, and turn on the computer.

10Enter BIOS Setup utility by pressing F1 when prompted during startup. Once in BIOS Setup utility, press F9. The default settings for the BIOS Setup utility are loaded.

11Select a BIOS field that you want to change by using the − (up arrow) and ↓ (down arrow) keys. Press ENTER, then reenter the values you wrote down at the beginning of the BIOS update process.
