VECTOR
GRAPmC, INC.
Using
Your Drive Configurations
On a
system
with
two
floppy drives, the double slots
let
you run a program
diskette
in
the A drive and a
data
diskette in the B drive. This way you
can
use programs
that
take
up
more volatile memory than the
RAM
may
contain.
Both
hard
and
floppy-only
systems
allow you
to
select
single-sided
or
double-sided
formats
for
the
floppy
drive
or
drives.
This
gives
you
the
opportunity to insert program diskettes of either format, should you
purchase
or
already
own
another
Vector
with
compatible
software,
or
if
you
are
considering a software package which is available
on
one or the other
type
of
diskette.
There
are
two
programs
that
you
will
use
to
select
and
use
single-
and
double-sided floppies. To specify the type of each logical drive in the system,
use
the
CONFIG F program. This option of the
CONFIG
program allows you
to
use the same physical drive as two
different
logical
configurations.
The
screen
provides
prompts,
allowing
you
to
select
either
single-sided
or
double-sided configuration for each logical floppy drive.
Once
the
drives have been specified, you will need
to
FORMAT
all new blank
diskettes. The
FORMAT
program reads the specification for each logical
drive
and
formats
the
diskette
accordingly.
This program erases
the
diskette and
puts track and sector markings in the
locations
that
Vector 4
CP
1M
will
look
for
them.
These
track
and
sector
markings
are
the
indicators
that
the
aDOS
uses
to
keep track of
aU
the allocation units and extents used in a file.
Further
Memory
Divisions
An
additional
(but optional) system division is the user area. This allows you,
if
you
choose,
to
specify
a
section
of
the
disk
as
an individual user area.
You
can
take advantage
of
up
to
sixteen different
user
areas;
the
default
is
User Area
O.
The highest
numl?er
you
can
use is 15.
Once you
are
operating inside
that
area, you should
treat
it
just
as if
it
were
its
own disk.·
That
is, entering
Dm
while working
in
user
area
5 on Disk B
will not display
any files stored
in
user
area
1
on
Disk
B.
This
gives
you a
further
way
to
divide
your storage; you can also allocate your computer use
among several people or tasks, assigning
each
a
different
user
area
on
the
disk.
It
is
worth noting
that
a user
area
is
not
a physical separation
on
the
disk or
diskette.
The
operating
system
simply
considers
it
different
for
file
management. In
that
respect, user areas
are
entirely unlike diskettes:
there
is
no
maximum
size
to
any individual user area, except the maximum
size
of
the
recording
medium
(hard or floppy disk) which uses
it.
