Note
that
if
keyboard
electronics
and
a remote
terminal
are
both
present in a system,
they
will
both
be
enabled. Similarly, if accessory
card
keyboard electronics
and
a
remote
console
are
both
present in a system,
they
will
both
be
enabled, provided no
other
keyboard electronics
are
present.
When
more
than
one
set
of
accessory
card
keyboard electronics
is
present,
then
the
one
with
the
lowest select code
is
enabled.
If
several
HP
98700s exist on a system,
then
it
is
the
user's
responsibility
to
ensure
that
the
accessory
card
keyboard electronics associated
with
the
HP
98700 display controller
at
the
address 56000016 has
the
lowest select code
of
all accessory
card
keyboard electronics in
the
system.
This
must
be
done
to
ensure
that
the
keyboard associated
with
HP
98700 "A"
is
not
input
console while
the
display
of
HP
98700 "B"
is
output
console.
The
Boot
ROM does
not
attempt
to
verify
the
display/keyboard
relationship.
If
no
output
device is present,
but
a keyboard
is
present,
then
that
keyboard will still
act
as
the
console
input
device. Similarly, if no
input
device is present,
but
a video
output
is present,
then
that
video
output
will still
act
as
the
console
output
device.
If
neither
an
input
device
nor
an
output
device
is
present,
the
Boot
ROM
will go
ahead
and
autornatically
Boot
the
default
operating
systems as long as no errors
are
discovered
during
self test. Refer
to
the
section on
Self-Test for more details.
Remote
terminals
as consoles
are
discussed in more detail in
the
next section.
