Making a Bootable CD

Anyone know if its possible to create a Boot CD to boot QNX from CD? Are
there any requirements for this such as a writeable filesystem somewhere,
etc…

Yes, I did it. No specific requirements, it is basically same thing as
write-protected floppy, just bigger.

  1. Create a ‘staging’ directory on HD with layout you want. I usually have
    ‘bin’, ‘lib’, ‘usr’ and ‘etc’ there.
  2. Populate those as you need. You probably need /usr/lib/teminfo/… stuff
    to use terminal apps.
  3. Create boot image, with driver capable of handling your CD (eide or
    scsi). In the boot script start the driver to mount your CD as “/”
    filesystem. Create a link from /dev/shmem to /tmp, or use devf-ram to create
    virtual /tmp if you will need a writable filesystem (QNX itself does not
    need it).
  4. Use mkisofs to create bootable CD image.
  5. Use anything (Adaptec Easy CD Creator will work) to burn it.
