Owner`s manual

Generally, all EMS boards should have
the
same
values in
their
page
frame
registers so
that
they
all use
the
same 64K
window in
the
physical
memory
space
of
a computer. How-
ever,
if
you wish
to
write
your
own
software, use
the
page
register
that
best suits
your
specific applications.
The
Everex
EMM.syS device
driver
provided
to
manage
EMS
memory automatically tries
to
find a contiguous 64K
space between C4000
and
FOOOO
if
no
user-specified address
is supplied (it will set
the
page
frame
register accordingly).
However,
if
the
page
frame
software
registers
are
to
be set
directly with
the
user's
own
software, they must
be
set
prior
to
accessing
any
of
the
mapping
registers.
NOTE: Writing to the page frame registers
will
destroy the
contents of the mapping registers.
