4.BIOS CONFIGURATION
Award's BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration. This type of information is stored in batterybacked CMOS SRAM so that it retains the Setup information when the power is turned off.
4.1. ENTERING SETUP
Power ON the computer and press <Del> immediately will allow you to enter Setup. If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the "RESET" bottom on the system case. You may also restart by simultaneously press <Ctrl>, <Alt>, and <Del> keys.

∙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.
Other Memory
This refers to the memory located in the 640 K to 1024 K

BIOS CONFIGURATION
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.
