Ask
Apple
What
does
ProDOS
do
thai
OOS
doesn't?
ProDOS directly
suppons
all
Apple disk
storage
devices, including
large.cap3city
hard
disks. ProDOS increases the accessibility
of
disk
storage
bcausc
of
extra commands. Also, disk
read
and
write
functions
are faster
under
ProOOS.
What's
booting?
In
computer
lerminology, boolin,g
(or
bool5lrappirzg)
means
surting
your computer. When you
tum
on
!he power, a built-in
program
(the
MonilOr prognam) is
put
inlo memory,
where
it turns
on Ihe disk
dnve.
The disk drive
lhen
tnnsfers
the $Urtup
program
on
Ihe disk 10 Ihe
computer's
memory. A111his must
happen
before
the
computer
is ready
to
work, So, figuratively,
booting
is
the
computer
pulling itself
up
by
its
own
bootstr1lps.
Is
my
Apple
very
Cr:tgiIe? I
'\\"0")'
about
brroking
lL
Your Apple is
aboul
as fragile as a television
set
or
stereo. You can't
break your Apple
by
pressing the wrong keys, juSt as you
an'l
break
your
1"
set
by
turning 10 the
wrong
channel
Are
disks
Cr.agiIe?
Disks are a
\0(
more su5Ceplibie
lO
damage
Ihan
your
computer
In
fact,
damaged
disks
are
probably
lhe
mOSl
common
ClIU$C
for
what
people
Ihink is a
broken
computer
or
buggy
software. With 5.25-
inch
disks,
dUSI
is
a major offender.
To
guard
against dust, always
keep
S.2S·inch disks in their envelopes
and
in
some
kind
of
disk
stonge
casc
or
box
(even
a
shoe
box). Although not as dangerous,
dust is
no
friend to 3.5-inch disks either.
However,
with 3.s-inch
disks,
Ihe
danger
comes
from introducing
dust
into the disk dri\'e.
Keep disks
away
from
extreme
heal, sunlight, liquids,
and
anything
that conl2ins a magnet, like a
telephone
or
magnetic
copy
sund
When
preparing
labels for 5 25-inch disks, write
on
Ihe
label first,
lhen
stick Ihe label
on
the
disk. ('This isn't necessary ",tith 3.S-inch
disks,
beause
of
their hard plastic
ase..)
If you musl write
on
a label
that's already
on
a S.2S-inch disk,
usc
a felt-tip
pen,
nther
than a
ball-point
pen.
A pencil
or
a ball-point
pen
could
dent
the
surface
of
the disk. l'\ever try to
ense
a disk label.
Enser
panicles can
damage
either kind
of
disk.
