The following reply was made to PR bin/115406; it has been noted by GNATS. From: dfilter@FreeBSD.ORG (dfilter service) To: bug-followup@FreeBSD.org Cc: Subject: Re: bin/115406: commit references a PR Date: Mon, 17 Aug 2009 16:16:59 +0000 (UTC) Author: marcel Date: Mon Aug 17 16:16:46 2009 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.
