F5 moves to the next disk. From that next disk F5 moves on to the next
disk again and so forth until there are no more disks and then it moves
you back to the first disk. No F6 or greater.
F5 will only successfully move on if there is a FreeBSD MBR (*) on the
next disk. If there is not such an MBR, the F5 option is displayed but
will not work (maybe beep?) and after a while you will timeout and boot
whatever default you have.
Bad idea to lose the MBR from a disk in the middle of a chain, but easy
to put back booting from CD1.
So as the OP had:
F5: Disk 2 (Windows)
but had not put FreeBSD MBR on that second disk, F5 did nothing and then
the F1 default kicked in and booted FreeBSD. Had the MBR been on that
second disk it would have started to boot windows and then likely
rebooted because the disk was no longer in the same position in the
chain as it had been when Windows was installed.
I don't believe it is necessary for Windows to always be the first disk,
just that the disk has to stay in the same position as it was in when
Windows was installed, which is usually the first disk! (Never tested
(*) Actually I have no idea what would happen if you stuck some other
booter like grub or gag on a later disk. But blank (new) disk or
Windows MBR will not move on.
