x86: Add quirk for Intel DG45FC board to avoid low memory corruption
Commit 6aa542a694dc9ea4344a8a590d2628c33d1b9431 added a quirk for the Intel DG45ID board due to low memory corruption. The Intel DG45FC shares the same BIOS (and the same bug) as noted in: http://bugzilla.kernel.org/show_bug.cgi?id=13736 Signed-off-by: David Härdeman <david@hardeman.nu> LKML-Reference: <20100128200254.GA9134@hardeman.nu> Cc: <stable@kernel.org> Cc: Alexey Fisher <bug-track@fisher-privat.net> Cc: ykzhao <yakui.zhao@intel.com> Cc: Tony Bones <aabonesml@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: H.
