Utility for the ThinkPad T61 named MAC.EXE, packed in a 1004 KB ZIP. The name suggests a tool related to the MAC address, likely for writing or restoring the network adapter address, but no version or instructions are given, so check the contents before running it. Technicians use such tools after a board swap or EEPROM reflash to restore the original MAC address. Run it only on the intended hardware, usually from a DOS boot environment, and note the original address from the label beforehand.
