STARTUP AND SHUTDOWN
--------------------

To boot: type rl at the Load device prompt, then Ctrl-D at the "# "
prompt. You can then login as root or guest, without a password.

To shut down:

  $ su          # switch to root user
  # /opr/opser  # run operator services
  # h           # help
  # s           # shutdown
  # 0           # shutdown in 0 minutes
  Ctrl-E        # stop the SIM emulator
  sim> quit     # quit the SIM emulator

To fsck the disk shut down the system, then restart the simh emulator.
When you get to the "# " prompt, don't hit Ctrl-D (which starts multiuser
mode). Instead, type /opr/opser, then hit f.

Log out with: Ctrl-D.

ISSUES
------

I have only been able to boot this using the "classic" simh3x branch.

Ultrix 3.1 uses the old UNIX defaults '^H' for erase and '^?' for
interrupts, so use Delete, not Ctrl-C, to stop a program, and adjust your
terminal to emit '^H' when backspace is pressed (eg. in xterm type Ctrl
and left click, then select Backarrow Key (BS/DEL)).

USER MANAGEMENT
---------------

To add a user, first make his home directory and initial files:

  # mkdir /usr/guest

Then simply add your user to /etc/passwd with vi:

  # change the disabled *NOLOGINS* guest user account to
  guest::6:1::/usr/guest:

The first number here is the user ID, make sure its unique, the second is
the group ID. Normally, you use group 1 "other" on this system.

Then give his home directory the right permissisons:

  # chown guest /usr/guest

To remove a user, just delete his home directory with rm -rf, and then
remove his entry from /etc/passwd.

GENERAL USAGE
-------------

This version of Ultrix is essentially a modified V7, but it includes many
enhancements from the BSD camp as well as SysV changes. You will find a
handful of games in /usr/games in addition to essential BSD programs like
vi and more. The standard shell is the V7 Bourne shell, but you can also
use the more enhanced SVR2 shell, called sh5. TCP/IP is also available.
All in all, this is a surprisingly easy system to use. (compared to V7!)

Have fun :)
