  Log:
  Prototype (but functional) Linux-ish /dev/nvram interface to the extra
  114 bytes of cmos ram in the PC clock chip.  The big difference between
  this and the Linux version is that we do not recalculate the checksums
  for bytes 16..31.
  
  We use this at work when cloning identical machines - we can copy the
  bios settings as well.  Reading /dev/nvram gives 114 bytes of data but
  you can seek/read/write whichever bytes you like.
  
  Yes, this is a "foot, gun, fire!" type of device.
