New page

UNDER CONSTRUCTION! QNX had several demonstration live floppy releases, including QNX4. It comes basically in two flavours: one with supporting some network cards, and another one with modem support. This test drive description is about the latter one, on ubuntu linux (14.04) host under official ubuntu 0.74* dosbox.

== WARNING! ==

The included script and manual is dangerous. It needs sudo or root access to the target host, uses external dependencies, can cause damage and irrecoverable package dependency problems via apt installing, and may be harmful when you are not familiar with tcp/ip ipv4 networking or linux iptables/slattach/etc. tools.

=== Known limitations ===

* No mouse support, conjectured that QNX guest uses IRQ 12 for PS/2 mouse
* Supported resolution is 640x480 4bit by the guest with the emulated VGA cards

== Prerequisities under ubuntu ==

=== Internet settings ===

* A working internet connection is essential
* 192.168.7.0/30 network must be unused! Otherwise network range collision will happen, causing unpredictable results!
* TCP ports 23 and 2323 should NOT be used by other application, and might collide with firewall settings if there is any!

=== QNX demo floppy image ===

Its checksum is:
$ md5sum qnxdemo.dat
8f8d0361fe9b600e94d6aa9aff382b7e qnxdemo.dat
Some modem floppy versions might have different checksum (even if they are not corrupted)

=== Required ubuntu packages ===

And also the following packages needs to be installed:

$ dpkg -l | awk '/^ii *(iptables|ppp|socat|sudo)/{$1=$3=""; print tolower($0)}'
iptables amd64 administration tools for packet filtering and nat
ppp amd64 point-to-point protocol (ppp) - daemon
pppconfig all a text menu based utility for configuring ppp
pppoeconf all configures pppoe/adsl connections
socat amd64 multipurpose relay for bidirectional data transfer
sudo amd64 provide limited super user privileges to specific users

Install them with this command (usually needs root privileges)

$ apt-get install -y bash dosbox iptables ppp socat sudo

== The all-in-one script: runme.sh ==

Run as root, like:

sudo ./runme.sh

This is a hybrid shellscript - dosbox config file.

#!/bin/sh
true <<REM
[dosbox]
memsize=32
machine=svga_et4000
[serial]
serial1=modem listenport:2323
[autoexec]
mount e .
e:
boot qnxdemo.dat
REM

########### here comes the real script
# by Peter Naszvadi, 2012-2016
#
# Press F1 in qnx whenever it is possible
# F2 needed only when confirming resolution
# enter localhost for number, password, username
# pap/chap is okay
# dns server is google 8.8.8.8

exit 0

== Booting and configuring a session ==

Note that all settings will be lost after VM shutdown! It is a live system, altered settings could not be saved.

Only keyboard can be used, no mouse, so golden rules:
* F1 key should be pressed if there is a choice or pressing key is needed
* F2 needs to be pressed only when there is the video/resolution setting window. F2 means "done"
* Focus can be switched between graphical input fields by pressing TAB as many times as needed
* ENTER presses the focused button
* Cursor keys, CONTROL+ESC can navigate in or pop up start menu at GUI
* localhost is the only text to type as password, dial number etc.
* 8.8.8.8 g**gle DNS is used, so type it in the applicable window via pressing 8-[TAB]-8-[TAB]-8-[TAB]-8[TAB]
* Some TABs and PgUP/PgDN can scroll in web browser
