EMM386.EXE
The EMS memory manager provided with your TravelMate 3000 WinSX, the
EMM386.EXE device driver, conforms to version 4.00 of the Lotus/Intel/Microsoft
Expanded Memory Specification (EMS). EMM386.EXE enables areas of system memory
to be used as Expanded memory.
The EMM386.ExE device driver must be installed before you can use Expanded memory.
To install EMM386.EXE in its simplest form, include the following command line in
your CONFIG.SYS file before any other DEVICE commands that use Expanded memory
(for example, RAMDRIVE.SYS) so that the any other device drivers can use the memory
manager, but after the HIMEM.SYS command line:
DEVICE=C:\DOS\EMM386.EXE [options]
Parameters (also called switches or options) for the EMM386.ExE driver are described in
the Microsoft Windows User's Guide furnished with your new computer. After it loads,
the memory manager determines the amount of Expanded memory in the system and
performs any required initialization.
Note: Do not use EMM386.EXE with Windows 3.0 in 386 enhanced mode. If the
EMM386.EXE line has been added to your CONFIG.SYS file, delete the line when using
Windows 3.0 furnished with your computer.
Some application programs may require 'backfill' memory, which is the unused area of
standard memory that can be used by EMM386.EXE as Expanded memory. For example,
an application program may require only 256 KB or 512 KB of standard memory, leaving
384 KB and 128 KB of backfill memory space, respectively, for use as Expanded memory.
