: This function generates a new, unique 128-bit UUID for the system board. The algorithm is designed to guarantee that the number is unique until the year A.D. 3400. This is automatically assigned when you run this option on a board without a UUID, ensuring the system's unique identity in network environments.
The is a specialized utility tool originally developed by IBM (and continued by Lenovo) for service technicians and authorized business partners. Its primary function is to set or update system identification information —such as the serial number, machine type, and model—directly into the system's EEPROM after a motherboard (system board) replacement .
