YOUR ATARI XF551 DISK
DRIVE AND DOS
DDDDDDDDDDDDDDDDD
The
AlARie
XF551™ Disk Drive is an extremely
efficient,
high-
speed storage device which
great
ly enhances your ATARI XETM
or
XLTM
Computer system. Your ATARI Computer's memory
retains the
information
and instructions you enter through its
keyboard. But the computer's memory is limited in
size,
and
w ithout a storage device like the XF551
,
its contents are erased
each time you turn off the computer.
Your
ATARI XF551 Disk Drive enables you to store and manage
large amounts of
informat
ion in separate fi les on
diskettes.
With
your
ATARI XF551
,
you can call up your
f
iles by name, copy or
erase
them,
and manage them in many other
ways.
What DOS Does
To
store information on diskettes you need software that
allows your computer and
disk
drive to
communicate
with
each other about your
files. That
is where the Disk Operating
System - DOS for short -
fits into the picture.
DOS
(pro-
nounced
"doss")
is a program that enables your
computer
and disk drive to work together in storing
, retrieving,
and
otherwise managing your diskette fi
les.
DOS itsel
f
is
organ·
ized in files contained on the Master
Diskette.
You
must
load 005
into
your
c
omputer before it
can
work
w ith your disk
drive. Some
ready-made computer
programs
already
contain a version of DOS, sparing you the trouble
of
loadi ng it
separately.
But with
other
programs,
especially
those in c artridge form, you have to load DOS along with
the
program if you plan to use a disk drive w ith
t
he
program.
In
any case,
you need DOS for
many
essen
t
ial tasks: to prepare
blank diskettes to store your fi
les,
for
example,
and to make
backup copies
of
important
fi
les
and
diskettes.
