I'm guessing that this might be indicative of the problem, but I'm
not sure. Acheron is the i386 server. Philemon is the iMac that's
trying to boot off of the i386.

If anyone has any ideas, I'd enjoy hearing them. I'm not yet particularly
familiar with the protocols. Thanks in advance for suggestions or pointers!
