allow the UNDI NIC interrupt to happen.

iSCSI hack.

This reverts commit 3cb133d27d.

This reverts commit ed06bd8a89.

This reverts commit 9e7b165017.

really ugly hack at present, but that doesn't hugely matter since I'm
aiming to change the interface to iSCSI devices anyway within the next
week.

already handled the INT13 call.

Inhibit -Werror when generating Makefile rules, to prevent warnings
from killing the dependency list.

Add some of the missing parts to libkir.h.

This driver really needs to be rewritten.
It tries to build both ISA and PCI images,
and makes life diffifult for the build system
and rom-o-matic.net.  The warning was just a reminder
that it needs to be cleaned up and re-factored
to split the PCI and ISA drivers.

This ancient ISA driver should probably be removed.
It is hard to get a card to test it with, and there
are comments to the effect that it cannot work with
relocation.  I would be quite interested to get a
bug report by someone who actually has this card.

Even though it is only currently used for rom-o-matic.net code,
it is good to make sure it gets built, and that the parsing code
is working.
