Hi Don,
Only access to the CMOS-RAM contents is via ports 70h/71h, on AT-style 
machines [vice MCA/EISA].  RTC values are stored in the CMOS-RAM, along 
with all the variables selected from the [firmware{EEPROM or Flash 
based}] BIOS menus, in addition to items like the shutdown status byte 
etc.  BIOS code is cast-in-silicon until the next EEPROM/Flash upgrade.
