UUID
The Universal Unique Identifier (UUID) is a 128–bit number
uniquely assigned to your computer at production and
stored in the EEPROM of your 24RF08. The algorithm that
generates the unique number is designed to provide
unique IDs until the year A.D. 3400. Consequently, no tow
computers in the world will 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 Maintenance Diskette and restart
the computer.
2. When the IBM logo is displayed, press the "ESC" key
few times until BIOS copyright and diagnostics screen
appears.
3. Select 3. UUID Data Utility from the main menu then
make a selection to read or create the UUID data.
A new UUID is created and written. If a valid UUID already
exists, it is not overwritten.
