Configuring Memory
D.1 Introduction
This appendix describes the various areas of RAM within the TM5000 Series
Notebook Computers and how you can make the Notebooks more efficient
by configuring them with the memory management device drivers supplied
with your computer.
D.2 Memory Areas
MS-DOS directly accesses up to 640 KB of RAM for the execution of programs
and commands and for storing temporary data. 
MS-DOS cannot directly
access memory beyond this 640-KB limit. The amount of standard default
RAM...

D.2.1 Extended Memory
Extended Memory is defined as internal system RAM above 1024 KB.
MS-DOS or your applications (that support Extended Memory) can access
Extended Memory if your system is configured with an Extended Memory
driver (XMS). Extended Memory drivers manage the Extended Memory
ensuring that two programs do not use the same part of memory. The
enhanced mode of MS Windows uses Extended Memory to multitask
applications.
MS-DOS includes the HIMEM.SYS Extended Memory driver. HIMEM.SYS is
defined...

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:...

D.3.2EMM386.EXE
The EMS memory manager provided with your computer, EMM386.EXE,
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,...
