[syslinux] isohybrid --mac doesn't find the mac efi image

[Thomas Schmitt]

Hi,

it comes to me that there is already an option which can
be used to enforce a new Section Header before the entry
which describes macboot.img.

Option -eltorito-id can be used to set the Id String of the
Section Header of the current boot image.
efiboot.img is to be stored under the default Id String of 28
0-bytes. So a new Section Header will emerge, if macboot.img
gets attributed a different Id String:

  ...
  -eltorito-alt-boot \
  -e boot/macboot.img \
     -eltorito-id "MAC" \
     -no-emul-boot -isohybrid-gpt-basdat -isohybrid-apm-hfsplus \
  ...


Have a nice day :)

Thomas
