I'm sorry but it's not possible to remove the BIOS supervisor password. The motherboard will need to be replaced.
From the service manual:
"If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee."
