Installing v7 on SIMH

2020-07-21T23:10:15Z

Decuser: /* Additional Information */

This is the procedure I'm using to install [[Unix Seventh Edition|Research Unix v7]] on [[SIMH]]'s [[PDP-11]] emulator.

I'm using the files from [[TUHS]] "/Archive/Distributions/Research/Keith_Bostic_v7/" directory. I've also uploaded the resulting tape to [https://sourceforge.net/projects/bsd42/files/Install%20tapes/Research%20Unix/Unix-v7-Keith-Bostic.tap.bz2/download here].

If you are going to build the tape then you'll need the [[Mkdisttap.pl#Research Unix v7|mkdisttap.pl]] script to output a v7.tap file.

I just hit enter to the "Overwrite last track" question, then the bootloader will appear. We are going to load the 3rd program on the tape, mkfs and format the 'a' partition.

<pre>

Once the formatting is complete, then it'll drop back to the bootloader, and we are going to load the 4th program which is the restore program, and we'll restore the root partition.

Now we can boot up UNIX from the hard disk, and setup the OS. The console driver echoes everything in upper case letters, however all command are entered in lowercase. We'll set stty to lowercase and speed up carriage returns and linefeeds.

As of November, 4, 2017, version 1.6 of the tutorial covers the basic installation from tape to disk, booting from the disk, reconfiguring the system, rebuilding the kernel, logging in as root, and as dmr, sending and reading system mail, and enabling the V7 instance and SimH to allow multiple sessions from the host machine to the instance via Telnet.

If you wish to use the backspace key when your terminal sends ^? (DEL) and Ctrl-C as interrupt character during login and everywhere else, apply [https://vpsland.superglobalmegacorp.com/backspace.diff this patch] to the kernel and rebuild the system.
