FRU replacement notices
Retaining the UUID:
The Universally Unique
Identifier (UUID) is a 128-bit number uniquely assigned to
your computer at production and stored in the EEPROM of
your system board. The algorithm that generates the
number is designed to provide unique IDs until A.D. 3400.
No two computers in the world have the same number.
When you replace the system board, you must set the
UUID on the new system board as follows:
1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.60, and restart the computer.
2. From the main menu, select 4. Assign UUID.
A new UUID is created and written. If a valid UUID
already exists, it is not overwritten.
