I only see that you restricted yourself to read only parts of the
mkisofs man page...
-hard-disk-boot
Specifies that the boot image used to create "El Tor-
ito" bootable CDs is a hard disk image. The hard disk
image must begin with a master boot record that con-
tains a single partition.
-no-emul-boot
Specifies that the boot image used to create "El Tor-
ito" bootable CDs is a 'no emulation' image. The system
will load and execute this image without performing any
disk emulation.
-no-boot
Specifies that the created "El Torito" CD should be
marked as not bootable. The system will provide an emu-
lated drive for the image, but will boot off a standard
boot device.
