DOSGEN COMMAND
10. 1 -- Use
The
version
and
revision
numbers
or
MDOS
will
be
automatically supplied by the DOSGEN command.
The
opeTato~
is
then given a chance to lock
out an
area
of the diskette.
This area
~ill
not be accessed by any
MDOS
command
or function since
i t
is an allocated block without a
RIB.
This permits the operator to set aside
a
part
of
the
diskette
for
his
own use.
All
MOOS inrormation must be in
files in order to be accessed
by
MDOS.
The
message
LOCKOUT ADDITIONAL SECTORS?
is displayed to allow sector lockout.
An "N"
response
will
cause
DOSGEN to continue with the next step; no sectors will
be locked out;
leaving as much diskette space as possible for
conventional
rile
use.
A
nyu
response
will
cause
the
follOwing messages to be shown:
ENTER STARTING SECTOR (HHH):
ENTER ENDING SECTOR (HHH):
The operator can respond with only a carriage
return,
which
will
casue
the
lockout request to be bypassed.
Otherwisel
the response must be a valid hexadecimal
sector
number
for
each
prompt.
The
secto~
numbers
entered
must
meet the
following criteria in order to
cau~e
the
specified
diskette
area to be locked out:
1.
The sector numbers must
be
hexadecimal.
2.
The
starting
sector
number
must
be
the
physical sector number of the
first
cluster
to
be
locked out.
The
ending sector number
must be the physical
sector
numbe~
oT
the
last
cluste~
to be locked out.
3.
The
starting sector number must be less than
or
e~ual
to
the
ending sector numbeT.
If
the
two
numbers are equal,. only one cluster will
be locked out.
4.
Both
secto~
numbers must be greater than
$18
and
less
than
$700
if
generating
a
single-sided diskette.
or
greater
than
$18
and
less
than
$FA4
if
generating
a
double-sided diskette.
In either
case,
the
locked
out
area
should be located such that
the largest block of free
space
resides
in
sectors
with
numbers
less than that of the
start of the locked out area.
DOSGEN
