            ThinkPad SATA Optical Disc Drive Firmware Update Utility
           ==========================================================

This utility will examine your system configuration and detect all SATA
Optical Disc Drives installed.  It will then check the firmware revision
of the drive and judge whether your PC requires a firmware update or not.
If required, it will prompt you to run the appropriate firmware update
program for your drive.

Note) USB drive is not supported by this utility.

==== Important Notice ====

   properly function until you shut down and reboot PC.
   Before executing a drive firmware update, be sure of following;
  - Remove a disc from the Optical Disc Drive.
  - Close all the applications besides of the Firmware Update Utility.
  - Verify that the AC power cord is connected to outlet and adapter
    cable is connected to PC firmly.
  - Make sure that a charged battery pack is installed in PC.
  - Do not power off, remove a drive or eject/insert disc tray of the
    drive during an update.  Otherwise your drive may become damaged.

B) This utility contains several executable files. 
   DO NOT RUN THESE PROGRAMS except FWWINOD.EXE.
   Running these programs other than FWWINOD.EXE could ruin your Optical
   Disc Drive.

     save it in a temporary folder on your disk (i.e. C:\TEMP)

     a firmware update, you cannot continue executing firmware update.
     Press "Cancel" button to exit the utility.
