QNX Demo Disk screen shots
QNX is a powerful real-time operating system. You may have used QNX
and not even known it. QNX is used in industrial, network, telecommunications,
medical, and automotive devices.
A while back QNX made available two 1.44 meg bootable demo disks. Each
disk boots and loads completely from a 1.44 meg floppy disk. No hard disk
is required! Each disk contains the OS, GUI, PPP or networking, Web browser,
file browser, and several demo applications.
There are two demo disks, a network version that uses a network interface
card attached to a network, and a modem version that uses PPP to an internet
386 or better.
8 megs of ram.
Hardware / RS232 modem (not a winmodem) or NE1000/2000, DEC 21x4x, or 3com
509 based network card.
Serial or PS/2 mouse.
VGA or Vesa 2.0 compatible card.
No hard disk needed
Please note that the network version only supports a couple of old network
cards and will therefore not work in more recent computers. (Sadly there
is no minimum standard for network interface card compatibility, as a result
every model of NIC requires a unique driver).
Additionally the modem version does not recognize the lobotomized "winmodems"
most people unfortunately have now days (winmodems lack the hardware processors
that older real modems have and therefore require proprietary software
from the manufacturer to emulate this hardware).
After QNX boots up and is configured, it starts the Voyager web browser.
The QNX demo disk also includes a minimal workspace menu and taskbar.
The file browser lets you look at the files loaded in the ramdisk, although
it does not do much else.
The "QNX Is Cool!" demo spins the text "QNX IS COOL!" in a window. You
can open up multiple instances of this and they will continue to run smoothly.
Here is an example of typical user interface controls used by the system.
This is the display configuration utility. On video cards with VESA
2.0 standard support you can set the Photon GUI to run in higher resolutions
and color depths such as 1024*768 in 24 bit color. (Some cheaper cards
cut corners and do not support this standard).
These screen shots were taken using BOCHS in basic VGA mode, so some
of the graphics do not look as nice as they should.
You can (or could) install extensions to the demo disk from the QNX
web site. No data is saved back to the demo disk so such extensions would
need to be loaded each time QNX started.
Also shown here is the included Notepad application. Likewise anything
edited in notepad will not be saved to the demodisk, just to the ramdisk.

And finally of course, the obligatory screen shot of yet another browser
