[cctalk] Re: gunkies.org - ultrix-11 installation example ...

Okay, we'll start with the basics. Download http://www.bitsavers.org/bits/DEC/pdp11/magtapes/ultrix-11/Ultrix11-install… . This is a pre-formatted tape made for use in SIMH. Make a reasonable pdp11.ini; mine looks like: -- set cpu 4M set cpu idle set tq0 lock att tq0 Ultrix11-install.tap set tq1 dis set tq2 dis set tq3 dis set rl dis set rp dis set rq0 rd54 att rq0 rd54-0.dsk set rq1 dis set rq2 dis set rq3 dis set xq type=deqna ;attach to whatever device you have... -- run "boot tq" and then you should be at the point where you can follow the instructions from https://www.tuhs.org/Archive/Distributions/DEC/Fred-Ultrix3/setup-3.1.txt Now for the more advanced stuff: I had a recollection of having problems with installing Ultrix 3.1 on RA disks so I went back through the install procedure and confirmed this - the installer creates a /usr partition that is too small to hold the initial dump from the install tape. So if you're going to install on a simulator the drive should be an RD series. Ironically the RD31 gets the largest /usr partition. I don't know how much testing this distribution got, or who it was marketed to - I would be very interested to hear reports of it being used in the field. -Henry On Thu, 19 Oct 2023 at 11:15, hupfadekroua via cctalk <cctalk(a)classiccmp.org> wrote:
