Installation instructions

Note: This utility is a bootable diskette based program, so you need to prepare a Floppy Diskette Drive (FDD) for your ThinkPad. Please consult with documentation accompanied with your ThinkPad system. If you encounter a problem attaching a FDD to your ThinkPad, please call your local Help Center.

  1. Place a blank, formatted floppy diskette in the A: drive.
  2. Close all open applications
  3. Click the file link above to download the file from the Web page.
  4. When prompted, select a drive and directory in which to save the downloaded file.
  5. Run the FWCD2101.exe file you downloaded to create the bootable diskette.
  6. Follow the instructions on the screen to create the diskette.
  7. When the diskette has been created, place the diskette in the ThinkPad system that has the CD-ROM drive to be updated.
  8. Boot the system from the diskette.
  9. Drives that have been detected will be listed in the upper area of the Main Menu. If a drive that requires an update is detected, it will be shown with a blinking mark on the left. If you find no blinking mark, your CD-ROM drive has latest firmware and no need to update or the update firmware is not for your drive. Please remove this diskette and shutdown your ThinkPad.
  10. Follow the instructions on the screen to update the necessary CD-ROM drives.
  11. When the installation is complete, remove the Firmware Update Utility diskette from floppy disk drive and power off your ThinkPad system. Do not restart the ThinkPad system with the ctrl-alt-del keys.


  • The diskette contains several executable files other than FW.EXE. Do not run these programs. Running these programs other than FW.EXE could ruin your CD-ROM drive.
  • The update utility can not identify a hard disk drive in the docking station, with the exception of the 570 UltraBase. In this case, remove the drive from the docking station and install it in a device bay of your ThinkPad system and then boot this diskette. If you encounter a problem installing the hard disk drive into the ThinkPad system , please call your local Help Center.
  • Do not power off the ThinkPad system during firmware update, or the CD-ROM drive may not be usable anymore.
