b) Bootable El-Torito images may have several problems, that result in a new
image that is not bootable, or that boots from an outdated session. In many
cases it is recommended to add boot info again in the new session.
- isolinux images won't be bootable after a modify. This is because
isolinux images need to have hardcoded the root dir lba in their boot
information table.
libisofs makes an educated guess at load time whether a boot image
contains such a table. Its outcome can be inquired by call
el_torito_seems_boot_info_table().
If one knows to have isolinux or GRUB El-Torito-bootable images, or if
a boot information table seems to exist, it is advised to apply the
el_torito_patch_isolinux_image() function.
Most boot images are highly dependent of the image contents, so if the
user moves or removes some files on image it is possible they won't boot
anymore.
b) Bootable El-Torito images may have problems, that result in a new image that
is not bootable, or that boots from an outdated session. In some cases it
might be necessary to add boot info again in a new first session.
- There is no safe way to modify hidden boot images, as the size of the
boot image can't be figured out.

Collection of Boot Sector Formats for ISO 9660 Images
by Thomas Schmitt - mailto:scdbackup@gmx.net
Libburnia project - mailto:libburn-hackers@pykix.org
This information is collected from various sources. Some is backed by
specifications, some is just rumor which happens to work (maybe not even that).
Content
EL Torito CD booting, for PC-BIOS x86, PowerPC, (old) Mac, EFI.
MBR, for PC-BIOS x86 from (pseudo-) hard disk

EL Torito CD booting
for PC-BIOS x86, PowerPC, (old) Mac, EFI
Sources:
El Torito, Bootable CD-ROM Format Specification, Version 1.0, 1995
which refers to ECMA-119, the standard for ISO 9660 filesystems.
libisofs/eltorito.[ch] by Vreixo Formoso.
man mkisofs by Joerg Schilling.
ECMA-119 prescribes that the first 32 kB of an ISO 9660 image are System Area
with arbitrary content. This prescription is obeyed by PC-BIOS systems only
if the ISO 9660 image is presented on CD, DVD or BD media.
In this case the El Torito Boot record is the starting point of booting.
The Boot Record is a ECMA-119 Volume Descriptor which is eventually located
at 2 kB block number 17 (decimal). Its content points to the location of the
Boot Catalog.
The format is described in part by ECMA-119 8.2 "Boot Record" and further
specified by El Torito figure 7.
Byte Range | Value | Meaning
---------- | ---------- | ----------------------------------------------------
0 - 0 | 0 | Volume Descriptor Type. 0= Boot record
1 - 5 | "CD001" | Standard Identifier

75 -2047 | 0 | Unused
---------- | ---------- | ----------------------------------------------------
el_torito is the constant string "EL TORITO SPECIFICATION" padded by 9 zeros.
cataloglba has to be provided by the file system generator.
The Boot Catalog lists the available boot images which may be prepared for
multiple system architectures, called "platforms".
It consists of one or more 2 kB blocks. The content is a sequence of fixed
format entries, 32 bytes each.
The entries are grouped in sections, which assign the entries to a particular
system architecture. The booting system will then choose an entry from an
appropriate section.
Byte Range | Value | Meaning
---------- | ---------- | ----------------------------------------------------
0 - 31 | ========== | Validation Entry

32 - 63 | ========== | Initial/Default Entry

---------- | ---------- | ----------------------------------------------------
An architecture is refered by a Platform Id number.
Defined by El Torito are:
0 = "80x86" which is used for standard PCs with Intel x86 or compatible CPU
1 = "PowerPC" (possibly for IBM machines with PowerPC CPU)
2 = "Mac" (possibly for Apple computers with MC68000 or PowerPC CPU)
Further in use by GRUB2 is:
0xef = EFI, a competitor resp. successor to PC-BIOS, possibly in use with
Intel ia64 Itanium and possibly with newer Apple machines.
Words resp. numbers are represented are little-endian.
Validation Entry:

The boot image file content is mostly opaque to the ISO 9660 image generator.
Nevertheless there is a tradition named "Boot Info Table" which prescribes
to write information into byte fields of the boot image file content.
There are no general means known how a producer of ISO 9660 images could
detect the need for Boot Info Table production.
It rather needs a hint from the user who has to know whether the boot image
expects a Boot Info Table.
The Boot Info Table begins at byte 8 of the boot image content.

MBR
for PC-BIOS x86 from (pseudo-) hard disk
Sources:
http://en.wikipedia.org/wiki/Master_boot_record
Mailing list conversations with H. Peter Anvin and Vladimir Serbinenko.
The candidates for MBR booting will normally use El Torito rather than MBR
if the ISO image is presented on CD, DVD, or BD media.
The eventual MBR comes into effect if the image is on a media that is
interpreted by the BIOS as some kind of hard disk. Usually real hard disks,
floppy disks, USB sticks, memory cards.
An important part of an MBR is the DOS style partition table. It describes up
to four primary partitions. There are two formats used for block address:
Cylinder/Head/Sector (C/H/S) and Logical Block Address (LBA). Both are based
on units of 512 bytes. So MBR_LBA = ISO_LBA * 4.
For C/H/S, the sector address is broken up into whole cylinders, remaining
heads, and remaining sectors + 1. The nomenclature seems to stem from antique
drum storage.
There are two parameters, sectors_per_head and heads_per_cylinder which are not
stored in the MBR. So it is more or less arbitray how to convert a LBA into
a C/H/S address and vice versa. For maximum range of C/H/S addresses one
may use sectors_per_head = 63 , heads_per_cylinder = 255.
Words are composed little-endian style.

---------- | ---------- | ----------------------------------------------------
By tradition the MBR itself and possibly more blocks are not claimed by any
partition. But starting the first partition at a non-zero block address causes
on Linux a partition device file (e.g. /dev/sdb1) which cannot be used to mount
the ISO filesystem.
libisofs is able to produce a second set of trees and meta data which is
suitable for being mounted at start block 16 (ISO) resp. 64 (MBR).
See <libisofs/libisofs.h> for call iso_write_opts_set_part_offset()
and http://libburnia-project.org/wiki/PartitionOffset for examples with
program xorriso.

SYSLINUX Isohybrid MBR
Sources:
syslinux-3.72/utils/isohybrid , a perl script by H. Peter Anvin = hpa.
Mailing list conversations with hpa.
An isohybrid MBR directs the booting BIOS to an ISOLINUX boot image which
is also the target of an El Torito boot catalog entry.
For that purpose one has to take an MBR template and has to set a few bytes
to values which sufficiently describe the ISO image and the boot image file.
Words are composed little-endian style.

hpa about MBR templates and partition table filesystem types:
"[MBR templates] are available in the Syslinux build tree under the names:
mbr/isohdp[fp]x*.bin
The default probably should be mbr/isohdppx.bin, but it's ultimately up
to the user.
[...]
Note: the filesystem type is largely arbitrary, in theory it can be any
value other than 0x00, 0x05, 0x0f, 0x85, 0xee, or 0xef. 0x17 ("Windows
IFS Hidden") seems safeish, some people believe 0x83 (Linux) is better.

SUN Disk Label and boot images

The Disk Label is written to the first 512 bytes of the image. It can mark
8 partitions (slices ) of which the first contains the ISO image. The other
7 may contain boot images.
Words are composed big-endian style.
Boot images are provided externally. mkisofs arranges them after the end of
the ISO image so that each starts at a cylinder boundary (320 kB).
There is a mechanism in mkisofs which fills unused partitions by copies of
their predecessor in the partition table:
"If the special filename ... is used, the actual and all following
boot partitions are mapped to the previous partition.
If mkisofs is called with -G image -B ... all boot partitions are
mapped to the partition that contains the ISO9660 filesystem."
