Realtime/Embedded UNIX: QNX
QNX is a realtime UNIX implementation which also includes window-system and few applications like a browser suitable for embedded systems (see IOpener). Since we just started to use it there isn't more to say about it, more later.

Demo 1.4MB Disk The 1.4MB demo-disk (as floppy-disk) booted with vmware:
- COM port IRQ's were not recognized (when you use PS/2 mouse it will work)
- NIC (network interface card) was not recognized, so not network capability
VMWare booting QNX 1.4MB demo-disk (K6-2/500 with 64MB)
RTP QNX RTP (real-time platform) is more complicate to boot, this is what we did: Install QNX RTP on your WinXX machine, it creates in Program\ Files/QNX/ a bunch of files (also the disk-image which can be 600MB in size), which we copied (via vmware-mount.pl) unto the virtual disk which we prepared as DOS VM. After booting press the SPACEBAR and select '5' (extending IDE detection-time), without this option the virtual IDE won't be detected (at least on our test-machine we used VMware).
The entire booting takes 10 mins (K6-2/500), so be patient:
VMWare booting QNX RTP (K6-2/500 with 16 MB)Due the very very slow booting the VMware approach with QNX is not recommended.
We installed the QNX-RTP (real-time platform) Beta under Win98 system, and our first impression after 24MB download: Great job they did in such a small binary download or system:

Setup The setup is easy, run the self-extracting/installing .exe file under WinXX, and answer a few questions, and after 10 mins you are done, reboot and the config.sys of your WinXX provides you the selection (it doesn't interfere MBR or a possible LILO there).

Package Manager I was most impressed by the graphical package-manager which I could connected via the net to the online list of ported applications. With literally "one click" you can install new software. We installed perl5 without any problems. The Linux-Community could learn about this, Debian does a great job, but seeing QNX providing this with their first Beta is impressive.
A package-mananger is something I personally consider as most important (e.g *BSD have it, and Debian too) as it makes maitainance of your system truly efficient. I was a former 'compile_from_source' fan, because I did not trust RPMs at all, but I also realized that all the .tar.gz I downloaded from the software authors had not always the system-layout I had (no matter which Linux-dist I used). *BSD and Debian I prefere nowadays (fall 2000) because of a clean UNIX system-layout.
