[rescue] Sun 3, Sunos 4, 3/60 Boot Block ?

[Chris Quayle]

Hi David,

A name from the past :-). I think the last time we spoke
was in the NetBSD Vax era, around v1.01, on a Microvax II,
iirc. Still hacking here, but semi retired now, 2 lads
left home and making their own way in the world, so more time
to start working through the to do list.

Anyway, Sun 3. This saga started with a Sun 3/150 deskside,
which had been in store for decades. Power supply failed on
initial power up, despite variac and replaced all the o/p caps
as well as other parts. It originally had the cpu board, 4
meg addon memory, scsi board and 7053 smd disk controller.
The 4 meg board fails self test, so 4 megs on cpu it is to
start with.

Had all the 3/60 dump files, so restored the files to the
server and setup tftp and bootparams. There's whole load
of old Sun to test and as you say, a boot server makes it far
easier.  Run into issues with that, but in the process, fired up
the 3/60 for clues and the system root partition failed. Had
it running for days in 2016, to play and to back everything
up, which in hindsight, wasn't such a bad idea. So now have 2
things to fix.

So, what about the boot block ?. All the docs say you should
be using munix, miniroot and sun install, where the bootblock
is automagically part of the process, but can't find anything
about standalone boot block install, which is a utility on later
versions of Solaris...
