No, I'm pretty sure it's slot 7. After I reload the saved state, it does
end up booting the hard drive. When I don't have the Turnkey disk in
there, it does start up from slot 6.

That might be it. It might be the version 2 ROMs that I have.

I think I'll try booting from another disk and typing in PR#7 manually
(with hard drive turned off) and see what happens.
