Are you saying that you do not have a serial EEPROM at all?  (A typical
configuration is using hardware jumpers, as the original NE2000 did.
But it's very atypical to not have a serial EEPROM at all.)

You can't.  The chip loads the station address into registers that were
ROM in the original design.  You can write a unique driver that can use
a chip without serial EEPROM, but you can't use a standard driver.
