TravelMate 3000 WinSX 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 (640 KB) in the
TravelMate 3000 WinSX is displayed on the Setup Program menu as Standard (Memory),
and it can be changed in 64-KB increments if your application program requires it.
MS-DOS accesses different areas of the computer's memory in different ways.  The
following memory map shows the available memory and how MS-DOS uses it.
