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
motherboard, or 640K for systems with 640K or more memory installed
on the motherboard.
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.
