AFAIK it won't hurt anything to make devices again, so give it another
spin. This seems to be the least of your problems, to wit:

What is a 'sdeng'? IIcis don't make the chimes of death; they usually just
don't do anything if they're insulted beyond the point of booting (which
yours is not).

If you actually observed this (!), I would blast the hard disk, make a
"small" MacOS partition, and install whatever full install you can find
(Apple allows downloads of 7.5.3 for free, though I prefer 7.1 and happen
to be a legal owner). 7.6 is fine too. A/UX installs its own version of
7.0.1, but that shouldn't make the Mac not power down.
