Now turn the S2 switch 4 ON.  When booting from ROMs EBOOT9.BIN or later.   It allows you to
change the MAC address and change the default IP address used for this Harrier DEBUG board.

NECDEBUG7.BIN has not been updated to be allowed to select the default number from 
reading the serial EEPROM connected to the AMD 79C973a Ethernet Chip.  This will be
changed to use this new feature in the near future.
