Flash BIOS update - CD-ROM ISO image version for ThinkCentre A61e (type 6416, 6417, 6418, 6449, 6453, 6495) Version 2ZKT33A Installation README This package updates the basic input/output system (BIOS) on ThinkCentre A61e (type 6416, 6417, 6418, 6449, 6453, 6495) systems. BIOS is programming that controls low-level hardware operations, including interactions with diskette drives, hard 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 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, 2zj933a.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 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. Follow the onscreen instructions. 6. Do not turn off the system during this process, wait until you see the following message: Flashing Complete Remove Floppy Diskette & hit to Continue 7. Remove the CD from the CD-ROM drive. 8. 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 drive.
