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 computer is displayed on the Setup Program menu as
Standard (Memory), and it can be changed in 64-KB increments if required
by your application.
The memory map in Figure D-1 shows the available memory and how it is
used by MS-DOS .
