QNX RTOS? (Apologies for off-topic!)

[Alex Funk <alf@FloydArt.com>]

My dear old mom sent me a clipping describing the QNX RTOS, which with a
GUI, an internet browser (with JavaScript, frames and animated GIF
support), and a dialer, is claimed to fit on one HD floppy.

I did the "Floppy challenge" and downloaded their zipped file from 
http://www.qnx.com/.  
The downloading, unzipping and floppy installation seemed to go
flawlessly but produced nothing that would boot either of my fairly
ordinary 200MHz Pentium PCs.  Not surprisingly, it didn't put any files
on the floppy that Windoze recognized, either.

Have any of you tried the process with better results?
