@ -345,16 +345,27 @@ Most bootable GNU/Linux CDs are equipped with ISOLINUX or GRUB boot
images. `xorriso' is able to create or maintain an El Torito object
which makes such an image bootable. For details see command -boot_image.
It is possible to make ISO images bootable from USB stick or other
hard-disk-like media by -boot_image parameter system_area= . This
installs a Master Boot Record which may get adjusted according to the
needs of GRUB resp. ISOLINUX. An *MBR* contains boot code and a
partition table. It does not hamper CDROM booting. The new MBR of a
hard-disk-like media. Several options install a *MBR* (Master Boot
Record), It may get adjusted according to the needs of the intended
boot firmware and the involved boot loaders, e.g. GRUB2 or ISOLINUX. A
MBR contains boot code and a partition table. The new MBR of a
follow-up session can get in effect only on overwriteable media.
MBR is read by PC-BIOS when booting from USB stick or hard disk, and by
PowerPC CHRP or PReP when booting. An MBR partiton with type 0xee
indicates the presence of GPT.
Emulation -as mkisofs supports the example options out of the ISOLINUX
wiki, the options used in GRUB script grub-mkrescue, and the example in
the FreeBSD AvgLiveCD wiki.
There is support for boot facilities other than PC BIOS: EFI, MIPS Big
Endian (SGI), MIPS Little Endian (DEC), SUN SPARC.
A *GPT* (GUID Partition Table) marks partitions in a more modern way.
It is read by EFI when booting from USB stick or hard disk, and may be
used for finding and mounting a HFS+ partition inside the ISO image.
An *APM* (Apple Partition Map) marks the HFS+ partition. It is read by
Macs for booting and for mounting.
MBR, GPT and APM are combinable. APM occupies the first 8 bytes of MBR
boot code. All three do not hamper El Torito booting from CDROM.
There is support for further facilities: MIPS Big Endian (SGI), MIPS
Little Endian (DEC), SUN SPARC. Those are mutually not combinable and
also not combinable with MBR, GPT, or APM.
*ACL* are an advanced way of controlling access permissions to file
objects. Neither ISO 9660 nor Rock Ridge specify a way to record ACLs.

Special "system_area=/dev/zero" causes 32k of NUL-bytes. Use this
to discard an MBR which was loaded with the ISO image.
*chrp_boot_part=on* causes a single partition in MBR which covers
the whole ISO image and has type 0x41. This is not compatible with
any other feature that produces MBR partition entries. It makes
GPT unrecognizable.
*prep_boot_part=* inserts the content of a data file into the
image and marks it by an MBR partition of type 0x96. The parts of
the ISO image before and after this partition will be covered by
further MBR partitions. The data file is supposed to contain ELF
executable code.
*efi_boot_part=* inserts the content of a data file into the image
and marks it by a GPT partition. If not chrp_boot_part=on, then
the first partition in MBR will have type 0xee to announce the
presence of GPT. The data file is supposed to contain a FAT
filesystem.
Instead of a disk_path, the word --efi-boot-image may be given.
It exposes in GPT the content of the first El Torito EFI boot
image as EFI system partition. EFI boot images are introduced by
bootspec efi_path=. The affected EFI boot image cannot show up in
HFS+ because it is stored outside the HFS+ partition.
*partition_offset=*2kb_block_adr causes a partition table with a
single partition that begins at the given block address. This is
