Emm386 Ü
ßßßßßßß
The expanded memory manager (EMM) for 386 systems (or better).
Syntax: EMM386 [on|off|auto] [w=on|w=off]
on | off
Turn expanded memory support on or off. Default=on.
auto
Only support expanded memory when a program asks for it.
w=on | w=off
Enables or disables support for the Wietek coprocessor.
Default=off.
Installing the EMM386.EXE device driver
You must use the device command to install the EMM386.EXE device driver
before you can use the emm386 command. If you try to use the emm386
command on a computer that does not have an 80386 or higher processor,
FreeDOS displays an error message.
Reactivating EMM386 expanded-memory support
If EMM386.EXE was loaded when FreeDOS started but is not currently in
use, the on parameter reactivaes expanded-memory options.
Suspending EMM386 expanded-memory support
If EMM386 expanded-memory support is currently active, handle 0 is
the only handle allocated, and EMM386.EXE is not providing access to
the upper memory area, then the off parameter suspends EMM386 expanded-
memory support. When EMM386 expanded-memory support is off, the
Lotus/Intel/Microsoft Expanded Memory Specification (LIM EMS) header
is changed so that programs cannot use expanded memory.
Enabling and disabling Weitek coprocessor support
If the w=on parameter is specified and the off parameter (different
from the w=off parameter) is not, EMM386 enables Weitek coprocessor
support. The high memory area (HMA) must be available to enable
Weitek coprocessor support.
If you specify w=on or w=off and no Weitek coprocessor is installed,
FreeDOS displays the following error message:
Weitek Coprocessor not installed
