...or DIY method involves these steps:

 - make a bootable floppy
   for hints, check here (study entire thread)
   http://www.openqnx.com/PNphpBB2-viewtopic-t7134-.html

 - test to make sure floppy disk boots okay.
 - save the floppy disk image to a file, using something like:

   dd if=/dev/fd0 of=cd_boot.img

 - copy 'cd_boot.img' and other CD files to directory where you are creating the ISO image, e.g. a sub-directory called 
'cdimage'

 - use mkisofs to create an ISO image
   commands will be something like,

  ./mkisofs -b cd_boot.img -c boot.catalog -l -R -o my_cd.iso cdimage

  where 'cdimage' is the working directory containing the CD files.

The mkisofs program is part of cdrecord package:

The tricky part will be to compile under QNX, given that the package was originally intended for other operating systems
, and QNX is sort of supported, but not 'officially'.

 - burn 'my_cd.iso' onto a CD using your fav burning program.

 - test it

 - if it doesn't boot, or boots but with errors, check previous steps carefully.
