+    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.

+
+
+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 it 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.

+ The default probably should be mbr/isohdppx.bin, but it's ultimately up

+ [...]
+ 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
