The EEPROM on the system board contains the Vital
Product Data (VPD) — that is, a computer serial number
and a system board serial number. When you replace the
system board, restore the computer serial number using
the VPD Data Utility in the ThinkPad CE Utility Diskette.
The serial number label is attached to the computer.

The EEPROM on the system board contains the Universal
