The Command which wrote the ISO image

mkisofs -J -v -T -o /media/IFREEAGENT/i386-dvd.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -m TRANS.TBL /root/mkrhdvd

*

-o /media/IFREEAGENT/i386-dvd.iso = -o is the output file name switch, we provide the output filename here

/root/mkrhdvd = is the path where we have copy and merged all the CDs, this is the out put of script in my previous posts, in next post i will give the edited version of that script, the exact you need to run from the cmd prompt.
