You are absolutely wrong.

If the CD is bootable, with the down dd command, the .ISO file is bootabl=
e.

That is true, checked by myself, for Power Macintosh, PReP, El Torito=20
(IBM PC compatibles 32-bit and 64-bit, and AmigaONE), Sparc, Intel Mac,=20
Pegasos/Efika and Amiga.
Surely it is true also for other architectures, as long as the CD is=20
standard at 2048-bytes/sec or 512-bytes/sec and dd gave no errors.
