All types ("any") of El-Torito boot images can be discarded or kept unaltered.

The latter makes only sense if the format of the boot image is
|

relocatable without content changes.
|

|

The boot image type "isolinux" can be kept unaltered (not advisable), or
|
||||
discarded, or it can be patched to match its relocation. In the latter case
|

the resulting ISO image is bootable if the boot image was really complying

An existing boot image of type "isolinux" can be
|
||||
kept unaltered (not advisable), or be discarded, or it can be patched
|
||||
to match its relocation. In the latter case the resulting ISO image is
|

bootable if the boot image was really produced by ISOLINUX.

|
||||
This is an expert option.
|
||||
xorriso cannot recognize the inner form of boot images.
|
||||
So the user has already to know about the particular needs of the
|
||||
bootimage which is present on the input media.
|
||||
.br
|
||||
Most safe is the default: "any" "discard".
|
||||
.br
|
||||
Regardless whether an El-Torito boot image was detected or not, it is possible
|
||||
to activate a set of ISOLINUX files for booting. An existing boot image gets
|
||||
discarded, then.
|
||||
The files have to be added to the ISO image by normal means (-map, -add, ...)
|
||||
and should reside either in ISO image directory /isolinux or /boot/isolinux .
|
||||
In that case it suffices to use as bootspec the text "dir=/isolinux" or
|
||||
"dir=/boot/isolinux". E.g.:
|
||||
.br
|
||||
-boot_image isolinux dir=/boot/isolinux
|
||||
.br
|
||||
It is possible to make several individual settings. E.g.
|
||||
.br
|
||||
-boot_image isolinux bin_path=/boot/isolinux/isolinux.bin
|
||||
.br
|
||||
-boot_image isolinux cat_path=/boot/isolinux/boot.cat
|
||||
.br
|
||||
-boot_image isolinux load_size=2048
|
||||
.br
|
||||
But that should hardly be necessary.
|
||||
.br
|
||||
CAUTION: xorriso only connects some ISOLINUX files to the El-Torito mechanism.
|
||||
If the ISOLINUX setup was incorrect or if the given files are not by ISOLINUX
|
||||
at all, then anything may happen when booting is attempted.
