## Notes on oskit: 2.11BSD system on a RP06 volume
|
|
|
|
### General remarks
|
|
See notes in [w11a_os_guide.md](../../../doc/w11a_os_guide.md) on
|
|
1. I/O emulation setup
|
|
2. FPGA Board setup
|
|
3. Rlink and Backend Server setup
|
|
4. SimH simulator setup
|
|
5. Legal terms
|
|
|
|
### System properties and intended usage
|
|
- patch level is #447 plus [fpsim+tcsh patch](https://wfjm.github.io/blogs/211bsd/2017-06-06-kernel-panic-here-doc-tcsh.html)
|
|
- for history see [CHANGELOG.md](CHANGELOG.md)
|
|
- This system is created for multi-user usage without Ethernet. The
|
|
`RETRONFPNW` kernel is configured with
|
|
```
|
|
INET YES # networking available
|
|
NETHER 0 # no Ethernet
|
|
NSL 1 # Serial Line IP enabled
|
|
```
|
|
- see [211bsd_rpeth](../211bsd_rpeth/README.md) for a system with `DEUNA` support
|
|
- see [211bsd_rpmin](../211bsd_rpmin/README.md) for a minimal memory system.
|
|
|
|
### Installation
|
|
A disk set is available from
|
|
http://www.retro11.de/data/oc_w11/oskits/211bsd_rpset.tgz
|
|
|
|
Download, unpack and copy the disk images (*.dsk), e.g.
|
|
```bash
|
|
cd $RETROBASE/tools/oskit/211bsd_rp/
|
|
211bsd_rp_setup
|
|
```
|
|
|
|
### Usage
|
|
|
|
- Start backend server and boot system (see section Rlink in
|
|
[w11a_os_guide](../../../doc/w11a_os_guide.md#user-content-rlink))
|
|
```
|
|
boot script: 211bsd_rp_boot.tcl
|
|
example: ti_w11 <opt> @211bsd_rp_boot.tcl
|
|
where <opt> is the proper option set for the board.
|
|
```
|
|
or use for verification the SimH simulator (see section SimH in
|
|
[w11a_os_guide](../../../doc/w11a_os_guide.md#user-content-simh))
|
|
```
|
|
pdp11 211bsd_rp_boot.scmd
|
|
```
|
|
|
|
- Hit `<ENTER>` in the `xterm` window to connect to backend server.
|
|
The boot dialog in the console `xterm` window will look like
|
|
(required input is in `{..}`, with `{<CR>}` denoting a carriage return:
|
|
```
|
|

erase, kill ^U, intr ^C
|
|
```
|
|
|
|
In first `'#'` prompt the system is in single-user mode. Just enter a `^D`
|
|
to continue the system startup to multi-user mode:
|
|
```
|
|
#^D

|
|
|
2.11 BSD UNIX (w11a) (console)
|
|
|
|
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 running. You can explore
|
|
the system, e.g. with a `pstat -T` or a `mount` command.
|
|
|
|
The second DL11 and the first four DZ11 lines can me activated too.
|
|
Also simple networking via SLIP and a DZ11 line, for details see
|
|
[using SLIP with 211bsd](../doc/211bsd_slip.md).
|
|
|
|
At the end is important to shutdown properly with a `halt`:
|
|
```
|
|
# {pstat -T}
|
|

|
|
65/208 inodes
|

|

|
|
# {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:
|
|

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