How to Configure Your System
What is a Configuration File?
The
configuration file config.sys
is
a file that contains certain com-
mands, which
MS·DOS
checks at startup. Each time you start MS·DOS,
it searches
the
root
directory
of
the drive in
which
it was started
for a file named
config.sys.
The
config.sys file allows you
to
configure
your
system
with
a
minimum
of
effort. For example, you can add device drivers
to
your
system by including special commands in
your
config.sys
file.
If
your
MS-DOS
disk does
not
have a config.sys file, you
can
use
the
MS·
DOS
line editor,
edlin,
to
create
one
and
then
save it
on
the
MS-DOS
disk in your
root
directory.
If
config.sys already exists
and
you
want
to change it,
YOll
can
use
edlin
to
edit
it.
