OK, so what am I doing wrong?

We have two SS20/71's sitting out waiting to be installed and delivered to
their final users.  Given that there's not a stitch on them and they're just
sitting doing nothing until then, I thought it would be fun to see if I could
boot the snapshot on one of them.

So I did basically what Peter had described: boot 4.1.4 CD, run "format" to
pre-partition the disk, boot the miniroot.  I then newfs'd /dev/sd0a and
mounted it on /a.  I unbundled {bin,etc,sbin,dev}.tar.gz into /a from a CD-ROM
I had burned with the 1.1 distribution and the April 12th snapsnot on it.
I then copied netbsd.gz to /a and gzip -d'd it.  I then copied boot.sun4m from
the miniroot into /a/boot.  Finally, I went to /usr/mdec and did the usual
"installboot -vl /a/boot bootsd /dev/rsd0a".  A couple of sync's and an L1-A,
and let's see what happens:

	ok boot -as
	[...]
	Boot: netbsd
	Size: 1114080+108520+69872 bytes
	data fault: pc=f80096ec addr=fe01c00c sfsr=3a6 <FAV>
	panic: kernel fault
	halted

	ok

Will only the May 4th snapshot kernel work?  And this April 12th one won't?

The machine has no floppy or tape drive or Ethernet attached (it's sitting
out in the middle of an area with nothing around it), so getting the newer
snapshot netbsd.gz (from May 4th) may be a bit of a pain in the arse.

Any ideas?
