I may be wrong, but I think that in this very case the usb stick is
considered as a hard drive, and should have a MBR. dd'ing the floppy on
a "hard drive" is unlikeky to give correct result since the FAT table
may be not on the right sector (if a MBR is expected, the partition
table in this case will be garbage)?


>From your remarks and after a cursory look to the sources in boot/ it
seems that when I suggested, in another thread, to type fd0!9pcflop.gz
(for El Torito) I was wrong since the BIOS services are not used after
the PBS, and this is a BIOS trick. But then I'm a bit puzzled about the
"fd0 sd0" print for choices for the files (unless the "boot" device
is always reported in the list, and since fd0 was given as the boot
device by the BIOS for use in PBS). Well this means that I have to study
more carefully the code before giving advices...

Mea maxima culpa.
