Grub2Win currently supports FreeBSD using the UFS filesystem. The ZFS filesystem is not yet supported.
I have tested Grub2Win with the PCBSD version 9.1 flavor of FreeBSD and it works well. The BSD kernel is loaded by the Grub kfreebsd command.
The default loader file for FreeBSD is /boot/loader. Since the UFS filesystem doesn't support partition labels, I have added the capability to search for the FreeBSD partition by the loader file name.
You can also specify a partition to load the kernel from by it's address or use the chainloader function to boot the FreeBSD disk MBR.
