No, i don't think so. If i'm not mistaken, it's only relevant for
memory pages belonging to the ``ISA hole'' (0xa0000 - 0xfffff), and
for pages that are used for a bus-master DMA controller, e.g. one of
the better SCSI controllers. If your OS/2 does already fail booting
the floppy, i don't think there's the problem.

Ooops, i don't have a clue. The only documentation i've got about
this is a German book describing the i386 (and marginally the i486)
architecture. You should be able to find a good book about this
elsewhere if you're seriously interested.

Yes, at least to the point where you can get the first shell access.
I think this will already require to put something onto the hard disk.
