Memory
The category is display-only which is determined by POST (Power On Self Test) of the
BIOS.
Base Memory
The POST of the BIOS will determine the amount of base (or conventional) memory
installed in the system. The value of the base memory is typically 512K for systems with
512K memory installed on the mainboard, or 640K for systems with 640K or more memory
installed on the mainboard.
Extended Memory
The BIOS determines how much extended memory is present during the POST. This is the
amount of memory located above 1MB in the CPU's memory address map.
Other Memory
This refers to the memory located in the 640K to 1024K address space. This is memory that
can be used for different applications. DOS uses this area to load device drivers to keep as
much base memory free for application programs. Most use for this area is Shadow RAM.
Total Memory
System total memory is the sum of base memory, extended memory, and other memory.
