OK That was annoying -- but telling!
I just spun up a 3yr old copy of Ubuntu Xenial, and the install went
exactly as it should have.
*So* what I've discovered;
Based on the FreeBSD experience (ATA/DVD timeout) and the OpenBSD6
install, which didn't experience that kind of difficulty, and in fact
proceeded to the install. But as soon as it setup the DHCP connection,
and proceeded to the next step; it Hung/Froze.
To me; it smells suspiciously like a timing related issue in the BSD's.
I see just today that Justin Hibbits (sp) is working on something that
looks related to this. But I fear the "low hanging fruit" he indicates
he's working on won't touch my old DP800. :-(

Anyone have any thoughts/suggestions?

Thanks for taking the time to read!
