Paul (and others!),

Well, I grabbed the 2.1.14 test kernel and tried it on my lonely little 5100.
(Which I accidently booted into Ultrix and discovered hadn't been up for 153
days!)

I was disappointed, but not suprised, to get an immediate register dump,
just as with the previous kernels.  I'm going to type it all in, with hopes
that you (or someone else on the list) might be able to make some sense of
it:

Here's what I get:

>> boot -f tftp(0,6)/tftpdir/dec_vmlinux
2..1..

Well, I _do_ have a copy of the MIPS architecture book, so maybe I'll take
a look and see if I can make any sense at all of this.  Of course, I may not
be able to get far without a map of the kernel.

Thanks!!
