I've been trying to figure how to boot a FreeBSD system with UEFI as opposed to BIOS-style.

I read the documentation, but want to boot a partition that might not be the first BSD partition on the hard disk.

For instance, some UFS partitions might have a NetBSD installation, a different FreeBSD installation, or no OS installation.

I read the man page (uefi) and looked at the files in /boot; have an EFI partition set up with more than enough space.

I would also want to be able to boot other UEFI-capable OSes including Linux, NetBSD (if that works), and Haiku when and if possible.
