Brilliant. I was just gearing up to start tracing the SCRIPTS stuff and
figuring out how/where it was going wrong. I'm so very glad you decided
to take a look at it, especially since I'm not sure I would've spotted
that issue at all.

I'll try your changes and test from there. I have an image of an
existing, working OpenServer install that I can try to boot by using
"link=slha" on the boot command line and see how I go, and there's the
install CD to test with as well.
