[K12OSN] Support for Etherboot on 486's with ISA NICs

Once you get into antique hardware :) the rules change. PXE and
etherboot were not around at that time (I don't think) so getting them
to work is a serious challenge. The most used process is to have some
other method of booting available (floppy or CD or even a hidden flash
card with an IDE adapter.)

Some really old stuff _may_ be able to netboot _if_ the add-on network
card has a boot rom AND the mainboard is able to handle that. You would
need to have the "corporate" pc's as the home user style would not have
the BIOS capability.

By the time you get to an ide-flash adapter plus flash card you are
halfway to a new, tiny thin client that is very low power and fanless.
The power savings alone would cover the additional cost over a couple of
years. Plus desktop real estate is at a premium as well.
