making a boot cd

i’m trying to create a qnx4.25 boot cd using mkisofs, but keep getting the
error that my boot image isn’t an acceptable size. i used knowledge base
ref# qnx.000010345 as a reference, but it doesn’t give any info on the
mkisofs command line. i’m using the command “mkisofs -b boot.image -c
boot.catalog -o /dos/c/bootcd.iso /cdboot” i’ve copied the .boot file from
my root directory into a directory called cdboot and called the file
“boot.image”.

as long as i don’t try to make boot cds (-b), the mkisofs program has worked
great for creating iso files. can anyone tell me the proper way it
implement the -b switch with mkisofs and qnx425.

thanks,
shontay

Hi Shontay,
The boot image is different from the “.boot” file you are using. When I
make a boot image, I do the following:

  1. Put a regular floppy disk in your floppy drive (make sure there’s nothing
    on it you want to save)
  2. dinit /dev/fd0
  3. mount /dev/fd0 /fd0
  4. copy the .boot file you want to use as the loader to /fd0/.boot
  5. cp /dev/fd0 boot.image

What you are doing is making a floppy image. The item copies the raw floppy
image from the disk and stores it in a file named boot.image.

Hope that helps,
Ron
