how to add files to puppy.iso? (Solved)

[andrei]

Is it possible to add arbitrary files to puppy.iso?

By default, it has files: boot.cat boot.msg initrd.gz isolinux.bin isolinux.cfg pup_201.sfs vmlinuz.
But this leaves 80% of the CD unused. Can I add some of my data
files, without making the CD live?

Then, when I run Puppy, I would mount the CD and be able to use those data files.

Perhaps I could, before burning the iso file on the CD, just open
it with some program and write additional files into it? And then burn
it? Is it possible, without using the "live CD" option?

yes, this should work:
copy the files from your CD and all new ones to /tmp/iso

then run this command:

mkisofs -o /root/puppy.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /tmp/iso

This creates a new iso /root/puppy.iso, that you can burn to CD.

If you don't have enough space in your pup001, burn it directly:

mkisofs -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /tmp/iso | cdrecord -tao -v dev=ATAPI:/dev/hdc speed=2 -data -overburn fs=16m driveropts=burnfree -eject -

This "pipes" the iso directly to cdrecord without storing it on the harddisk.
You might have to alter the values for your CD-writer.

Did not try myself, this is based on forum-messages I found searching for "mkisofs".

Why not burn the CD as a multisession Puppy live CD, then simply save the files you want to the CD? That way you have the Puppy OS and the files on the same CD, and the files will still be accessible from another Puppy by mounting the multisession CD.

If you really want the files on a separate CD, you can use one of the burning programs in Puppy to burn your files on a CD. You can even make it a multisession CD and leave it open for more sessions to be added later.

You can use burniso2cd to burn the initial multisession Puppy live CD. Some commercial burning programs have been reported capable of doing it too. I believe Nero is one.

Mark, I used your instructions to make an iso after I swapped the vmlinuz in puppy2.01 iso:

sh-3.00#
sh-3.00# mkisofs -o /tmp/puppy-201-highmem.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /tmp/Puppy-201-highmem
Size of boot image is 4 sectors -> No emulation

Then I used burniso2cd to burn a new DVD, then clicked the "save" icon to save the old settings to the new multisession DVD, shut down, restarted....

...And it works!

yeah, good news
Thanks for reporting the success
