From the CLI window, issue the
command:
ED s/Startup-Sequence
This loads the Startup-Sequence
for
the
screen editor.
The
commands for
using
the
screen
editor are
listed in Appendix B. Any
changes you
make
to
the
Startup-
Sequence
are carried
out each time the Amiga is booted up. So
,
to
create a
RAM
disk
automatically when
the Amiga boots up, type:
DIR
RAM:
after
the echo
"Use
Preferences tool to set date" line
.
To
add a
tool
,
use the CLI
copy command
to
create
that particular tool
and
assign
it
to the RAM disk
.
When
you
now reset the Amiga, there
will
be
a
RAM disk icon
along
with the
Workbench disk icon
.
To remove the RAM disk icon
and
have the
Amiga
boot
up normally, you need
only
re-enter the
screen editor for
the
Startup-Sequence
and
delete the DIR RAM
:
line
(and any other changes
that refer to the RAM disk)
you added to the Startup-Sequence
.
Setting the A501 Real Time Clock
The A501 Memory
Expansion
Unit increases the
amount of memory of
the
Amiga
500
to I Megabyte. In
addition,
'it has
a
battery backed up Real
Time
Clock.
This
clock
is different
from
the Clock tool
in
Workbench
(the
system
clock). Once
set
,
this clock keeps the
actual
time
continuously
,
and operates
even when
the Amiga is off.
You
set
the time for the Real Time Clock from CLI
,
using
the SetClock
command. Typically, you only
need to
set
the time
once,
using the
Save
option
of
this
command.
You
can
also load the time
from
the Real Time
Clock into the
system clock
with the Load
option of
SetClock
.
This
can
be
done automatically
by
changing
the Startup-Sequence
.

the
CLI
