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.
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.
Expanded Memory
Expanded Memory in memory defined by the Lotus/Intel/Microsoft (LIM) standard as EMS. Many standard
DOS applications can not utilize memory above 640 K, the Expanded Memory Specification (EMS) swaps
memory which not utilized by DOS with a section, or frame, so these applications can access all of the
system memory. Memory can be swapped by EMS is usually 64 K within 1 MB or memory above 1 MB,
depends on the chipset design.
Expanded memory device driver is required to use memory as Expanded Memory.
