This one I can sort of answer.  The following process has worked for me
on a U10 with an external drive:

1. At the 'ok' prompt, type in the command-- show-disks
2. It will show the disks and ask you to select the one you want.
    Select the external drive (They are labeled a, b, c, etc.  You should
    see a & b; pick the one corresponding to your external drive.  If it's
    not obvious from the disk name, by using brute force you can do this
    twice, once with the external drive on and once not.)
3. boot ^Y (Ctrl-Y), or 'devalias gentoo ^Y' and then 'boot gentoo'

If this doesn't appeal, you can wait for someone who actually knows the
easiest way to do this on a U5 & then do that.

At some point, you probably want to go to
http://docs.sun.com/app/docs/coll/216.1
and grab some OpenBoot documentation.

Somewhere on Sun's site is the answer to your exact question, but I
haven't any idea where, anymore.

Something else you can do is go to the #gentoo-sparc FreeNode IRC
channel and ask around there.
