Updating the BIOS

Flash memory simplifies distributing BIOS upgrades. If you need a new version of the BIOS, you can download the BIOS update from the Technical Support web site and install the new version from a disk.

To Update the BIOS

1.Enter BIOS Setup by pressing F2 when prompted during startup.

2.Write down the settings for each of the fields. (At the end of the BIOS update process, you will reset the fields to the default values.)

3.Exit the BIOS Setup program.

4.Download the correct BIOS file from the Technical Support web site.

5.Uncompress the contents of the BIOS file you downloaded, and copy the contents onto a bootable diskette.

6.Place the bootable diskette containing the BIOS files into drive A, and restart the system with the disk in the drive.

7.At the prompt, type:

PROGGTW and press ENTER.

8.The system asks you if you want to change the BIOS. Press Y and then press ENTER.

9.Once the BIOS files have been loaded, remove the disk from drive A and restart the system.

10.As the system starts up, verify that the correct BIOS version is reported.

11.Enter BIOS Setup by pressing F2 when prompted during startup. Once in BIOS Setup, re-enter the values you wrote down at the beginning of this process.

If you do not set the CMOS values back to the correct values, the system may function erratically.

Important!

You may encounter a CMOS checksum error or other problem after the system restarts. Try turning the system off and then restarting. CMOS checksum errors require that you enter BIOS Setup, check your settings, save your settings, and exit setup.
