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 FMM386SX.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 manuals for
information about VDISK.
