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 512 K for systems with 512 K memory installed on the
motherboard, or 640 K for systems with 640 K or more memory installed on the motherboard.
Other Memory
This refers to the memory located in the 640 K to 1024 K 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.
Extended Memory
The BIOS determines how much extended memory is present during the POST.
This is the amount of memory located above 1 MB in the CPU's memory address map.
