Retaining the UUID:
The Universally Unique Identi-
fier (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 unique
number is designed to provide unique IDs until the year
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. Select
4. Assign UUID
from the main menu. A new
UUID is created and written. If a valid UUID already
exists, it is not overwritten.
