System properties and intended usage

This system is build with Ethernet based networking via a DEUNA network interface. The kernel is configured with

    NETHER 1        # ethernet support
    NDE 1           # DEUNA interface driver
    NSL 0           # no slip available

For history see CHANGELOG.md.

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/
       wget http://www.retro11.de/data/oc_w11/oskits/211bsd_rpethset.tgz
       tar -xzf 211bsd_rpethset.tgz

Usage

• Setup Ethernet environment, see 211bsd_ethernet.md

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

       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

       checking quotas: done.

  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}
        43/186 files
        59/208 inodes
        11/150 processes
        10/ 46 texts active,  36 used
         2/135 swapmap entries,  525 kB used, 3654 kB free, 3648 kB max
        32/150 coremap entries, 2661 kB free, 2586 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

         R4: 005000  R5: 147510  SP: 147466  PC: 000014
  

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