Has anyone tried to write a device driver to support an EMS board under
Minix for the purpose of Virtual Memory ?  It does have the distinct
advantage that it can work even on an 8086 or 8088.  I do understand that
it would take some knowledge of the registers on an EMS board like a RAM
page or an Above Board, but that can't be all THAT hard to figure out the
software interface to.  The trick to this is that most of EMS is software
in DOS, the interfaces to map pages in, etc.  In a sense, this is good
because that will allow for flexibility to graft this in with the Minix
memory management scheme.  Face it - EMS is essentially virtual memory for
DOS.  I think that this might be a decent addition to Minix.
