Hardware Installation
To complete the mainboard installation, the peripheral device could be installed now. The basic system needs a display interface card.
If the PCI - Bus device is to be installed in the system, any one of five PCI - Bus slots can be used.
3.12. KEYBOARD & PS/2 MOUSE INSTALLATION
The main board supports PS/2 connector type keyboard & Mouse (CN5).
The BIOS will auto detect whether the PS/2 Mouse is installed or nor & assign IRQ12 for Mouse port if which was installed.
After installing the peripheral device, the user should check everything again, and prepare to power-on the system.
3.13. KEYBOARD SETTING FUNCTION
After booting the O.S., there are some special functions used by keyboard as follows:
"CTRL_ALT_DEL" − Pressing these keys simultaneously will cause
system to Warm Start (Software Reset).

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 battery-backed 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.
The other way to enter Setup is to power on the computer, when the below message appears briefly at the bottom of the screen during the POST
(Power On Self Test), |
press <Del> key |
or |
simultaneously |
press <Ctrl>, <Alt>, |
and <Esc> keys. |
|
|
Ÿ TO ENTER SETUP BEFORE BOOT PRESS CTRL-ALT-ESC OR DEL KEY
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.
If you do not press the keys at the correct time and the system does not boot, an error message will be displayed and you will again be asked to,
Ÿ PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP

∙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 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.
