Re: [Bug-xorriso] Adding files to an ISO image

Cough ... 0.5.6 is somewhat dusty meanwhile. In two days it will
be six years old.

My copy complains about the following unknown -as mkisofs options:
  -partition_cyl_align
  -partition_offset
  -partition_hd_cyl
  -partition_sec_hd
  -e
  -isohybrid-gpt-basdat

As a consequence the resulting ISO is bootable only via BIOS
resp. "legacy emulation" of UEFI. The image is ready for CD/DVD
and for USB-Stick:

  El Torito catalog  : 193219  1
  El Torito cat path : /boot/isolinux/boot.cat
  El Torito images   :   N  Pltf  B   Emul  Ld_seg  Hdpt  Ldsiz         LBA

If you encounter the need to boot via UEFI, then get
  http://www.gnu.org/software/xorriso/xorriso-1.3.8.tar.gz
and do
  tar xzf xorriso-1.3.8.tar.gz
  cd xorriso-1.3.8
  ./configure --prefix=/usr
  make
Afterwards you may run xorriso without installation by absolute
or relative paths. E.g. if you did above in your $HOME directory,
try:

  "$HOME"/xorriso-1.3.8/xorriso/xorriso -version


This version of xorriso will allow you to inspect the boot
equipment of your resulting ISOs:

  "$HOME"/xorriso-1.3.8/xorriso/xorriso \
     -indev test_redone.iso \
     -report_el_torito plain \
     -report_system_area plain

The meaning of the output lines is (roughly) explained by

   "$HOME"/xorriso-1.3.8/xorriso/xorriso \
     -report_el_torito help \
     -report_system_area help

Some technical background info is given in
   "$HOME"/xorriso-1.3.8/doc/boot_sectors.txt
Introductions to particular technical terms might be found in
wikipedia or wiki.osdev.org. (Your mileage may vary.)

I hope to release before end of the year a version which will
make it more easy to preserve and to manipulate boot equipment.
There is still a lot of testing and detail work to do.


Have a nice day :)
