Sel Up An AUTORUN lor Baal
When you boot your system with DOS
2.5,
the first thing that
happens is that
the DOS.SYS file
is loaded into memory and
run.
Before
loading
DUPSYS
or
transferring
control
to BASIC
or a
cartridge
,
if present
,
DOS determines whether a
f
ile
named
AUTORUN.SYS exists on
the boot
disk. If
so,
the
file is loaded
into
memory;
if
it was saved with a
run
vector
it
is also run (see
DOS Menu selections K and
L,
BINARY
SAVE and
BINARY
LOAD,
in Section
3).
You
can use option 3 on the
SETUP
utility menu to
create an
AUTORUN .SYS file on the diskette in
Drive 1 that
will
perform
either or bolh
of
these two functions:
Load the RS232 handler from an ATARI 850 Interface Module
(if
the
module is connected and turned on when
you
boot your
system),
and/or-
• Load and
RUN
a
BASIC program
from the boot
disk.
