  SVN rev 208899 on 2010-06-07 20:31:55Z by ae
  
  MFC r197608:
  
  The first 96 bytes may not be zeroes. It can contain trivial boot
  code that merely emits an error and waits for a key press before
  rebooting. The error being that extended partitions are not
  bootable. The origin is presumed to be Windows 2000; Windows XP
  does not do this...
  
  For now, ignore the first 96 bytes when checking that the EBR is
  (for the most part) all zeroes.
