FS: Thinkpad X20 only system restore CD

[JohnK]

For Sale: system restore CD for X20. This CD restores the hidden partition on your hard drive to restore the Thinkpad to its OEM software state including IBM software that came on the thinkpad when it was new and the W2K operating system.

I purchased this CD and successfully used it to restore my Thinkpad X20 to its orginal out of box configuration . My X20 was a model number 2662-39U. I do know the CD will only work on an X20 but I am not sure if it will work on all models of the X20.
