7.17 INTEL 387 COPROCESSOR
Removing and replacing the Intel 387™ Coprocessor requires that you remove the system board. The pressure exerted during the removal and replacement procedures may damage the sys- tem board if it is in the system unit during these procedures. Use the Universal Coprocessor re- moval tool to remove the coprocessor itself. Any other tool could bend or damage the pins. Because you must disconnect the battery during these procedures, you must run the SETUP pro- gram after you reassemble the computer.
