There appears to be a group of LC-II type machines that are in fact more
LC than LC-II in capability. I don't think that's what you have though
since you have identified this as an after-market enhanced system, but
somehow it isn't being recognized as a full upgrade.

Just guessing, but I suspect there's a jumper on the motherboard that
causes the ROM to identify the system as an LC even though the processor
has been upgraded to an LC-II type system. Other Mac systems use similar
techniques, but so far we haven't been able to pin this down on the

We've tried to force NetBSD to run on this type of system and have never
had any success even though NetBSD is capable of running on an '020 with
PMMU. I suspect that without figuring out what to change on the
motherboard to get the system to really think it's an LC-II, you'll be
out of luck.
