Flash BIOS update - CD-ROM ISO image version for ThinkCentre(R) 8104, 8105, 8106, 8107, 8108, 8109, 8117, 8118, 8119, 8120, 8121 Version 2GKT20A Installation README This package updates the basic input/output system (BIOS) on ThinkCentre 8104, 8105, 8106, 8107, 8108, 8109, 8117, 8118, 8119, 8120, and 8121 systems. BIOS is programming that controls low-level hardware operations, including interactions with diskette drives, hard disk drives, and the keyboard. The BIOS is stored on a chip. Your computer uses flash BIOS, which can be updated through a program on a flash diskette so that you do not have to replace the BIOS chip to update the BIOS. Note: Make note of any settings you have changed in the BIOS Configuration Utility. These settings may have to be re-entered after updating the BIOS. Print this file so that you can refer to it during the installation. 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 update ---------------------- 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, 2gj920a.iso. Use your CD-R software's feature for creating a CD from an ISO image; RecordNow! calls this feature "Burn Image". Refer to the help provided with your CD-R software for further assistance. Installing the update --------------------- 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. When you are prompted to select a country, press the number on your keyboard which corresponds to the country in which you are using the computer. For example, press 1 for the United States. 6. Press Enter. You will be asked if you wish to update the serial number of your machine. 7. Press N. You will be asked if you wish to update the machine type/model number of your machine. 8. Press N. The Phoenix Phlash16 utility will appear onscreen. 9. Wait until you see a message stating that the update has completed successfully. 10. Remove the CD from the CD-ROM drive. 11. 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.
