For a reader of the UEFI specs this comes very unexpected.

Together with the report of Pascal that a hard-disk-emulation works
even with mkisofs option -b (i.e. Platform Id x86 BIOS) it appears that
the UEFI implementation treats the El Torito boot image like the whole
device, regardless of Platform Id.
On (virtual) CD-ROM this makes some sense. But on virtual hard disk
(as reported by Pascal) it deviates from all tradition:
El Torito is not to be interpreted on hard disk. Not by BIOS, not by UEFI.

I am in doubt whether other implementations of UEFI do this too.


Have a nice day :)
