Author: marcel Date: Mon Aug 17 16:24:50 2009 New Revision: 196335 URL: http://svn.freebsd.org/changeset/base/196335 Log: MFC rev 196333: 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.
