Cassette
and
Disk Storage with
the
Apple lie
191
drive
is
not
specified in a DOS
command,
that
command
will
affect
the
diskette
in
drive
1.
In
other
words,
drive
1
is
the
default
drive.
If
you wish
the
command
to
affect
drive
2,
end
the
command
with
a
comma
followed
by D2. The
following
command
would
result in
the
directory
for
the
diskette in
drive
2
being
displayed:
CATALOG, D2
Once
D2
has
been specified, all subsequent DOS commands
will
affect
the
diskette
in
drive
2.
In
other
words,
drive
2
will
now
be
the
default
drive.
If
you wish
to
change
the
drive
affectedj)y
DOS commands back
to
drive
1,
merely
end
your
DOS
command
with
a
comma
followed
by D1. The
default
drive
will
then
be
drive
1.
Slot Specification
If
you wish
to
use
more
than
two
drives
with
your
lie,
an
additional
controller
card must be installed in
one
of
the
lle's
expansion slots. Generally,
the
second
controller
card
is
installed
in slot
4.
Again
two
drives can be
connected
to
this second
controller
card.
If
you
wish
to
reference
drives 3 and 4, you must use a second
parameter
known
as
a slot parameter. You
cannot
reference
these drives
as
D3
and D4.
The slot
parameter
follows
the
DOS
command
just
like
the
drive
parameter. The slot parameter must
be
separated
from
the
DOS
command
or
drive
parameter
with
a comma. The slot
parameter
consists
of
the
letter
S
followed
by
the
slot
number
containing
the
disk
controller
to
be
accessed.
The DOS
command
and any filenames must be specified first in
the
command.
However,
the
order
of
the
parameters
(drive
slot)
is
not
critical.
