modification history
--------------------
01d,29jan02,g_h  Add #ifdef INCLUDE_VWARE_LAUNCH before calling to
                 sysCheckIfVware().
01c,18jan02,g_h  Change NvRAM logic to work with visionWARE
01b,24sep01,g_h  move FCC & SCC routines to sysMotFccEnd.c & sysMotSccEnd
01b,07jul01,g_h  add support for defrent MAC address when
                 using the two channels.
