3.

Add a command to the CONFIG.SYS file to include the
memory manager as a device driver, as described in the

next section. The CONFIG.SYS file is used by MS-DOS to
set up the computer’s system configuration requirements.

Modifying the CONFIG.SYS File

If you have a word processing program that can save a file as

a text-only file (also called an ASCII file), you can use it to

add the memory manager to the CONFIG.SYS file. Follow

these steps:

1. Start your word processing program.

2.

Load the file CONFIG.SYS and add the following

command line:

DEVICE=EMM386SX.SYS

For information on optional parameters, see “Using
EMM386SX.SYS options,” below.

Note

you can copy the EMM386SX.SYS file to a directory

other than the root directory as long as you either
enter that directory in a PATH command (for example,

in your AUTOEXEC.BAT file), or include the pathname

on the DEVICE= command line. For example, if
EMM386SX.SYS is in the directory \DRV on drive C,
include the pathname like this:

DEVICE=C:\DRV\EMM386SX.SYS

If you plan to use any of your expanded memory to

create a virtual disk with the MS-DOS VDISK device
driver, be sure to insert the EMM386SX.SYS command

line before the VDISK command line in your
CONFIG.SYS file. See your MS-DOS Reference Manual
for information about VDISK.
