1. General remarks ---------------------------------------------------

   See notes on

     2.  FPGA Board setup
     3.  Rlink and Backend Server setup
     4.  Legal terms

   in $RETROBASE/doc/w11a_os_guide.txt

2. Installation ------------------------------------------------------

   - A disk set is available from
       http://www.retro11.de/data/oc_w11/oskits/211bsd_rkset.tgz
     Download, unpack and copy the disk images (*.dsk), e.g.

       cd $RETROBASE/tools/oskit/211bsd_rk/
       wget http://www.retro11.de/data/oc_w11/oskits/211bsd_rkset.tgz
       tar -xzf 211bsd_rkset.tgz

3. Usage -------------------------------------------------------------

   - Start backend server and boot system (see section 3 in w11a_os_guide.txt)
       boot script:  211bsd_rk_boot.tcl
       example:      ti_w11 -u @211bsd_rk_boot.tcl

   - 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 rk(0,0,0) at 0177404
       : {<CR>}
       : rk(0,0,0)unix

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

     The login prompt is sometimes mangled with the 'Device not configured'
     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}
         7/186 files
        39/208 inodes
        11/150 processes

        33/150 coremap entries, 2960 kB free, 2867 kB max
         1/ 10  ub_map entries,   10    free,   10    max
       # {mount}

       /dev/rk2h on /tmp
       /dev/rk3h on /bin
       /dev/rk4h on /usr
       # {halt}
       syncing disks... done
       halting

     While the system was running the server process display the
       cpumon> 
     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: 003000  R5: 147510  SP: 147466  PC: 000014
 
     will be visible. Now the server process can be stopped with ^D.
