you should not rely on the information found here, as it will be woefully
out of date.

EMM386
Enables or disables EMM386 expanded-memory support on a computer with an
80386 or higher processor. The EMM386 command also enables or disables
Weitek coprocessor support. Do not use this command when Windows is
running.
The EMM386 device driver, EMM386.EXE, provides expanded-memory support and
also provides access to the upper memory area. For information about
EMM386.EXE, see <EMM386.EXE>.
Syntax
EMM386 [ON|OFF|AUTO] [W=ON|W=OFF]
To display the current status of EMM386 expanded-memory support, use the
following syntax:
EMM386
Parameters
ON|OFF|AUTO

EMM386 device driver (if set to OFF), or places the EMM386 device driver

only when a program calls for it. The default value is ON.
W=ON|W=OFF
Enables (if set to W=ON) or disables (if set to W=OFF) Weitek
coprocessor support. The default value is W=OFF.
