--------------------
01e,29jan02,g_h  Add #ifdef INCLUDE_VWARE_LAUNCH before calling
		 sysCheckIfVware().
01d,25jan02,g_h  Remove unused varibale "uninit"
01c,18jan02,g_h  Change NvRAM logic to work with visionWARE
01b,24sep01,g_h  move FCC & SCC routines to sysMotFccEnd.c & sysMotSccEnd
01a,05may01,g_h	 adopted from sbc8260/sysNet.c (ver 01a)
