The Expanded Memory Manager included with MS-DOS (EMM386.EXE)

manages the interface between the program and Expanded Memory,

bringing data in and out through the page frame as required.

Before you can use Expanded Memory, you must install the

EMM386.EXE

device driver as described in the next section, “Memory Device Drivers.” You

need not install the Expanded Memory Driver if your application does not

support Expanded Memory.

D.3 Memory Device Drivers

The following device drivers included in the C:\ directory are provided to

manage memory:

• HIMEM.SYS — An Extended Memory manager that supervises the

computer’s Extended Memory so that no two applications use the same

memory at the same time

• EMM386.EXE — Supports LIM-EMS Expanded Memory

• RAMDRIVE.SYS — Supports RAM disks in standard, Extended, and

Expanded Memory

• SMARTDRV.EXE — For use with a hard disk and Extended or

Expanded Memory that supports disk-caching to speed up reading from

the hard disk.

D.3.1 Installing Device Drivers

To install a driver, add a DEVICE command line to your CONFIG.SYS file

similar to the following, using the MS-DOS EDIT utility or a word processor

that saves text files in ASCII format:

DEVICE=C:\DOS\XXXXXXXX.XXX [options]

Where XXXXXXXX.XXX is the name of the device driver, for example,

HIMEM.SYS. You must then restart the computer to load the new CONFIG.SYS

settings and activate the driver(s).
