 New Revision: 196333
 URL: http://svn.freebsd.org/changeset/base/196333
 
 Log:
   The start of the EFI GPT partition in the PMBR can always be represented
   by CHS addressing. Don't define these fields as 0xff, but rather define
   them correctly. This prevents boot problems on PCs where GPT is being
   used.
