Option -G is not related to the El Torito boot image isolinux.bin.
It inserts its data into the System Area of the ISO, which is
indeed limited to 32 KiB.
Use cases are MBR and other kinds of boot sector or partition table.

CD/DVD booting via BIOS should ignore this area.
Well ... i am experiencing strange things with repacked archlinux
ISOs which have no MBR. So "should" might mean "does not".


Have a nice day :)
