DOS Command emm386
Type: External (5.0 and later)
Syntax:
EMM386 [on|off|auto] [w=on|off]
Purpose:
Enables or disables EMM386 expanded-memory support on a computer
with an 80386 or higher processor. Do not use this command when
Windows is running.
Discussion
The EMM386 device driver, EMM386.EXE, provides expanded-memory
support as well as access to the upper memory area. In order to use
the EMM386 command you must have an 80386 or higher processor and
you must install the EMM386.EXE device driver by using the DEVICE
command in your CONFIG.SYS file, otherwise the following message
will be displayed:
EMM386 driver not installed
Options
on|off|auto - ON activates the EMM386 device driver, OFF suspends
the device driver, and AUTO places the device driver into auto mode.
Auto mode enables expanded-memory support only when a program calls
for it. The default value is ON.
w=on|w=off - ON enables Weitek coprocessor support. OFF disables
Weitek coprocessor support. The default is w=off.
Example
If you want to display the current status of EMM386 expanded-memory
support, enter,
EMM386
