It's got to know something else. MacOS X on my system set the boot string
to boot ...@0:8, where partition 8 was the one that had macOS X on
it. That didn't work on my system, unfortunatly...

All you have to do is set LOAD-BASE to something other than what it's
supposed to be for netbooting to work. ofwboot.xcf is set to load at
600000, and it works (netboot) for me w/ LOAD-BASE at 640000.
