As I got a VME cage for my 177, I finally was able to try to boot it.
However, it wasn't as easy as I hoped.

The 177BUG does a RARP before the BOOTP.  If the RARPS succeeds, then
the bootfile in the BOOTP response will be ignored which causes the
subsequent TFTP to fail.

I really need a mvme68k netboot which does DHCP instead of
RARP/bootparams.  Right now I have edit /etc/ethers at just the
right time to make it boot.  That's a pain.

The kernel died when configuring the osiop but since it's from
5/19 and fixes have been made since then, I'm going to try to cross
build a new kernel (or have someone build one for me).

This is somewhat short but I'm in a rush...
