Previous
versions
of
CP/M
would
either
return
you
to
the
Monitor
program
without
explaination
or
freeze
the
keyboard
thereby
forcing
you
to
hit
the
Reset
button.
4.3
Return
to
Extended Systems Monitor
executive
If
you
want
to
boot
up
from
a
different
disk,
or
make
use
of
any
other
Extended Systems Monitor canrnand
(see
Extended Systems Monitor
manual),
you
have
to
get
back
to
the
Monitor's
executive.
The
RESET
button
on
the
rear
of
the
computer
chassis
will
accomplish
this
but
is
not
always
convenient.
Therefore,
Vector
Graphic
CP/M
2.x
contains
a
special
canmand which
returns
control
to
the
Extended Systems Monitor
executive.
The
procedure
is:
after
the
CCP
A:>
prompt,
type
MONITOR
(return).
You
will
immediately
see
the
Monitor
prompt
appropriate
to
the
type
of
system
you
have.
4.4
Warm
start
If
you were
using
CP/M
and you
returned
to
the
Extended Systems Monitor
executive,
you can
generally
return
to
the
CCP
without
rebooting
your system
disk.
This
is
assuming
you
did
nothing
to
destroy
CP/M
in
memory.
Following
any
Monitor
prompt,
simply
type
G
0000.
In
some
Monitor
executives,
there
are
also
single
letter
canmands
that
accomplish
this.
In
the
4.1
Monitor,
depress
L
after
the
MON>
prompt.
4.5
Backing up
the
system
disk
.D:J
not
place
a
write-enable
tab
on
the
8"
CP/M
System
disk.
I:b
not
ever
modify
or
configure
this
disk.
You
are
allowed,
within
the
CP/M
licensing
agreement,
to
copy
this
disk
as
many
times
as
needed
for
your
own
system,
so
long
as
the
copies
are
not
sold.
Thus,
any
procedures
which
you
do
to
personalize
CP/M
for
your
particular
system,
as
described
later
in
this
part,
can
be
done
to
a COpy
of
the
master.
Such
a
copy
is
called
"Personalized"
Vector Graphic
CP/M
2.x
System Disk.
Immediately
after
cold
booting
your
serialized
Vector
Graphic
CP/M
2.x
System
Disk
the
first
time
r
create
a
Personalized
Vector Graphic
CP/M
2.x
System Disk.
Use
it
from
then
on.
The
following
is
the
procedure
for
copying
a
Vector
Graphic
CP/M
2.x
System
Disk
or
any
CP/M
2.x
data
disk.
Use
it
to
create
your
first
Personalized
disk
from
the
original.
Then,
use
it
later
to
create
subsequent
copies
of
the
Personalized
disk,
after
it
has
been
modified
as
explained
later
in
this
manual.
1)
