It's not about a particular version of xorriso, but about the set of command-line options that we use depending on the xorriso version: + #if [ "$XORRISO_VER" -le 10202 ]; then + # 1.2.2 shipping in wheezy + Echo "Using older EFI command line for xorriso $XORRISO_VER" + # Tell xorriso to create a secondary ElTorito boot record for the + # EFI bootloader + XORRISO_OPTIONS="${XORRISO_OPTIONS} -eltorito-alt-boot --efi-boot boot/efi.img" + # Add the efi image as a FAT partition too, so our CD image will + # also boot on a USB key (like isohybrid, just implemented + # differently) + XORRISO_OPTIONS="${XORRISO_OPTIONS} -append_partition 2 0x01 binary/boot/efi.img" + #else + # Echo "Using newer EFI support in xorriso $XORRISO_VER" + # XORRISO_OPTIONS="${XORRISO_OPTIONS} -eltorito-alt-boot -e boot/efi.img -no-emul-boot" + # XORRISO_OPTIONS="${XORRISO_OPTIONS} -isohybrid-gpt-basdat" + #fi In our tests, there are more computers where EFI boot works (from an USB key) when we use "-eltorito-alt-boot --efi-boot boot/efi.img -append_partition 2 0x01 binary/boot/efi.img" compared to when we use "-eltorito-alt-boot -e boot/efi.img -isohybrid-gpt-basdat". In particular a number of macbook.
