The 79c30 is not an Ethernet chip; it's the ISDN/audio chip.

This is more interesting.  Someone else reported a SCSI timing error to me,
which I haven not been able to track down nor reproduce.  I may be asking
your help (booting kernels, etc.)

An overflow occurred in the input path on the serial chip.  Not uncommon; the
SCCs on the DEC 3000s aren't very fast.

Because it failed to find the SCSI disk, it wasn't able to determine the
boot device.

It was developed on a 3000/xxx machine (a 3000/400, to be precise, I think),
but it is the case that not very many people run on this hardware anymore,
and the code isn't necessarily tested thoroughlt as a result.

As a side note, I too have a 3000/400 that I used to update quite regularly,
but have not been able to do so recently.  Sigh, maybe it's time I find some
space in the lab to set it up again.
