Notes on oskit: 2.11BSD system on a RP06 volume with Ethernet

General remarks

See notes on

System properties and intended usage

  • patch level is #447 plus fpsim+tcsh patch
  • for history see CHANGELOG.md
  • This system is build with Ethernet based networking via a DEUNA network interface. The RETRONFPETH kernel is configured with 
      NETHER 1        # ethernet support
  NDE 1           # DEUNA interface driver
  NSL 0           # no slip available

Installation

A disk set is available from http://www.retro11.de/data/oc_w11/oskits/211bsd_rpethset.tgz

Download, unpack and copy the disk images (*.dsk), e.g.

       cd $RETROBASE/tools/oskit/211bsd_rpeth/
       211bsd_rpeth_setup

Usage

  • Set up Ethernet environment, see 211bsd_ethernet.md

  • Start backend server and boot system (see section Rlink in w11a_os_guide)

         boot script:  211bsd_rpeth_boot.tcl
     example:      ti_w11 <opt> @211bsd_rpeth_boot.tcl
                   where <opt> is the proper option set for the board.

  • Hit <ENTER> in the xterm window to connnect to backend server. The boot dialog in the console xterm window will look like (required input is in {..}, with {<CR>} denoting a carriage return:

         70Boot from xp(0,0,0) at 0176700
     : {<CR>}
     : xp(0,0,0)unix
     Boot: bootdev=05000 bootcsr=0176700

    In first '#' prompt the system is in single-user mode. Just enter a ^D to continue the system startup to multi-user mode:

         #^D
     Fast boot ... skipping disk checks
     checking quotas: done.
     Assuming NETWORKING system ...
     add host w11a: gateway localhost

     login:

    The login prompt is sometimes mangled with system messages, if its not visible just hit <ENTER> to get a fresh one.

         login: {root}
     erase, kill ^U, intr ^C

    Now the system is in multi-user mode, daemons runnng. You can explore the system, e.g. with a pstat -T or a mount command. The second xterm can be activated too, it will connect to a second emulated DL11. At the end is important to shutdown properly with a halt:

         # {pstat -T}
      48/186 files
      66/208 inodes
      16/150 processes
      11/ 46 texts active,  38 used
       3/135 swapmap entries,  669 kB used, 3510 kB free, 3504 kB max
      34/150 coremap entries, 2417 kB free, 2339 kB max
       1/ 10  ub_map entries,    7    free,    7    max
     # {mount}
     /dev/xp0a on /
     /dev/xp0c on /tmp
     /dev/xp0d on /home
     /dev/xp0e on /usr
     # {halt}
     syncing disks... done
     halting

    While the system was running the server process display the

         cpu0>

    prompt. When the w11 has halted after 211bsd shutdown a message like

         CPU down attention
     Processor registers and status:
       PS: 030350 cm,pm=k,u s,p,t=0,7,0 NZVC=1000  rust: 01 HALTed
       R0: 177560  R1: 010330  R2: 056172  R3: 000010
       R4: 005000  R5: 147510  SP: 147466  PC: 000014

    will be visible. Now the server process can be stopped with ^D.
