PMBR is a simple variant of MBR which does know enough to parse GPT partition table and how to load bootcode from the "freebsd-boot" partition. Then gptboot does search bootable UFS partition. At this time we do not have any bootcodes like booteasy for GPT. But you can try to use bootme and bootonce GPT attributes (see gpart(8)). Also you can use grub boot loader. --=20 WBR, Andrey V.
