It's not impossible to make a kernel without uninitialised data, just
annoying... With the right linker flags, it should be easy enough, I'd
think. When we have a linker ;-)

I've noticed this before. I suspect it is the case that the PROM will only
boot BCS (which is a lot older than ELF and COFF, after all) and that we
might need to write a converter from ELF to BCS.

People keep talking of an AV300 manual which details lots of interesting
hardware information. I don't suppose that someone has one plus a digital
camera or scanner?
Also, has anyone managed to extract the AV5500 ROM image? I've tried in the
past on a running DG system, but didn't have much success. Since it's
capable of booting from the net, booting from SCSI and doing a variety of
diagnostic tests, it would probably make interesting reading...
