  13     *  --------------------
  14     *  01a,26jun02,gtb  derived from ptswarm_devs.
  15     *                            -Deleted intiatialization of 3rd ethernet port.
  16     *                            -Added M41T81 SMBus RTC
  17     *                            -NVRAM environment variables moved to
  18     *                             eeprom on SMBus 0
