Important Note

==============

Installing this update involves creating a BIOS flash CD and running the flash program from the CD. You must have access to a CD-R or CD-RW drive and CD-R software which is capable of creating a CD from an ISO image.

Downloading the package

=======================

1. Click the file link to download the file from the web page.

2. When prompted, select a drive and directory in which to save the downloaded file.

Create the bootable CD

======================

Create a CD from the CD ISO file, 5ZJT22A.iso.Use your CD-R software's feature for creating a CD from an ISO image; Record Now! calls this feature "Burn Image". Refer to the help provided with your CD-R software for further assistance.

Installing the package

======================

1. Close all open applications.

2. Insert the bootable CD into your CD-ROM drive.

3. Shutdown the computer.

4. With the CD still inserted in the CD-ROM drive, power on the system.

5. The current BIOS level on the system is compared to that on the flash update CD. If the levels are the same, or the level on the CD is older than the ROM, a message is displayed stating: "BIOS ROM file is older than (or same as) BIOS ROM image. Continue Anyway? (y/n)"

6. The update may take up to 2 minutes. Do not power off or restart the system during this procedure!

7. Wait until you see a message stating that the update has completed successfully.

8. Remove the CD from the CD-ROM drive.

9. Press Enter.

Note: If your system boots back to a 1962 POST error or displays a picture of a diskette on the screen, enter the Setup utility by pressing F1 during startup and change the Startup options to include your hard disk drive.
