Chapter 2 |
Installing the Motherboard to the Casing
Most computer chassis will have a base on which there will be many mounting holes that allows the motherboard to be securely attached and at the same time, prevents short circuits.
There are two ways to attach the motherboard to the base of chassis:
zwith stud zor with spacer
Please refer the figure below show the studs and spacers, they may have several types, but all look like the figure below:
In principle, the best way to attach the motherboard is with studs, and only if you are unable to do this should you attach the board with spacers. Take a careful look at the motherboard and you will see many mounting holes on it. Line these holes up with the mounting holes on the base. If the holes line up, and there are screw holes this means you can attach the motherboard with studs. If the holes line up and there are only slots, this means you can only attach the motherboard with spacers. Take the tip of the spacers and insert it into the slots. After doing this to all the slots, you can slide the motherboard into position aligned with the slots. After the motherboard has been positioned, check to make sure everything is OK before putting the casing back on.
The figure below will show you the way to fix the motherboard using with the stub and spacer:

2-3 |
Note: If the motherboard has mounting holes, but don’t line up with the holes on the base and their are no slots to attach the spacers, don’t worry, you can still attach the spacers to the mounting holes. Just cut the button portion of spacers (the spacer may be a little and hard to cut off, so be careful of your hands). In this way you can still attach the motherboard to the base without worrying about short circuits.
Sometimes you may need to use the plastics spring for isolate the screw from motherboard PCB surface, because the circuit wire may be near by the hole. Be careful don’t let the screw to contact any printed circuit wire and parts on PCB that near by the fixing hole, otherwise it may damage the board or cause the board malfunction.

Standard External Connectors
Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are usually connected one-by-one to connectors located on the motherboard. You need to carefully pay attention to any connection orientation the cables may have and, if any, notice the position of the first pin of the connector. In the explanations that follow, we will describe the significance of the first pin.

Introduction of BIOS |
3-1 |
Chapter 3 Introduction of BIOS
The BIOS is a program located on a Flash Memory chip on the motherboard. This program will not be lost when you turn the computer off. This program is also referred to as the boot program. It is the only channel for the hardware circuit to communicate with the operating system. Its main function is to manage the setup of the motherboard and interface cards parameters, including simple parameters such as time, date, hard disk drive, as well as more complex parameters such as hardware synchronization, device operating mode, CPU SOFT MENU™ II techniques, setup of CPU speed. The computer will operate normally, or will operate at its best, only if all these parameters are correctly configured through the BIOS.
0Don’t change the parameters inside the BIOS unless you know what you are doing
The parameters inside the BIOS are used to setup the hardware synchronization or the device operating mode. If the parameters are not correct, they will produce errors, the computer will crash, and sometimes you will even not be able to boot the computer after it has crashed. We recommend that you do not change the parameters inside the BIOS unless you are familiar with them. If you are not able to boot your computer anymore, please refer to the section “Erase CMOS data” in Chapter 2.
When you start the computer, it is controlled by the BIOS program. The BIOS first operates an auto-diagnostic for all the necessary hardware, configures the parameters of the hardware synchronization, and detects all the hardware. Only when these tasks are completed does it give up control of the computer to the program of the next level, which is the operating system. Since the BIOS is the only channel for hardware and software to communicate, it will be the key factor for system stability, and to ensure that your system performs at its best. After the BIOS has achieved the auto-diagnostic and auto-detection operations, it will display the following message:
PRESS DEL TO ENTER SETUP
Three to five seconds after the message is displayed, if you press the Del key, you will access the BIOS Setup menu. At that moment, the BIOS will display the following message:

Chapter 3 |
Fig 3-1 CMOS Setup Utility
In the BIOS Setup main menu of Figure 3-1, you can see several options. We will explain these options step by step in the following pages of this chapter, but let us first see a short description of the function keys you may use here:
zPress Esc to quit the BIOS Setup.
zPress (up, down, left, right) to choose, in the main menu, the option you want to confirm or to modify.
zPress F10 when you have completed the setup of BIOS parameters to save these parameters and to exit the BIOS Setup menu.
zPress Page Up/Page Down or +/- keys when you want to modify the BIOS parameters for the active option.
CMOS DATA
Computer Maybe you have heard somebody saying that their CMOS knowledge DATA was lost. What is the CMOS? Is it important? The CMOS is the memory used to store the BIOS parameters that you have configured. This memory is passive. You can read its data, and you can also store data in it. But this memory has to be powered by a battery, in order to avoid any loss of its data when the computer is turned off. Since you may have to change the CMOS battery when it is out of power and if doing so, you will loose all CMOS data, therefore, we recommend that you write down all the parameters of your hardware, or to
put a label with these parameters on your hard disk.

However, differences will exist because of the various brands and types available.
<Note 3> SEL100/66# Signal:
This default setting is “High” at 100MHz, and “Low” at 66MHz. When you want to try a higher multiplier factor at 100MHz and cannot chose it in “High” state, then you can set it to “Low” state.
Note: According to Pentium® II/III processor types, some Pentium® II/III processors will have locked up the multiplier factor and disable this signal. In this situation, there is no way to choose the higher multiplier factor.
<Note 4> AGPCLK/CPUCLK:
Introduction of BIOS |
3-5 |
Default setting is “ 2/3”. In this state, AGP bus speed will be CPU bus speed divided by 3 and times 2. If you choose the setting to “ 1/1 ”, AGP bus speed will equal to CPU bus speed.
<Note 5> L2 Cache Latency:
Sixteen setting are available, Default, and 1 to 15. This item can let you adjust the processor L2 cache speed, the larger the value, the faster the L2 cache will run. You have to be aware that if you set the L2 cache speed too fast, it will cause the L2 cache to fail. If the L2 cache fails it will cease to run until you reset the value, but the processor and L1 cache will still function, just not as well. To make sure your L2 cache functions properly please choose an appropriate setting. The default setting is Default.
<Note 6> Speed Error Hold:
Default setting is “Disable”. If you choose the setting to “Enable”, when CPU speed setting is wrong, then system will hold.
Normally, we do not recommend that you use the “User Define” option to setup CPU speed and multiplier factor. This option is for setup of future CPUs whose specifications are still unknown. The specifications of all present CPUs are included in the default settings. Unless you are very familiar with all CPU parameters, it is very easy to make mistakes when you define by yourself the external clock and the multiplier factor.
Solution in case of booting problem due to invalid clock setup:
Normally, if the CPU clock setup is wrong, you will not be able to boot. In this case, turn the system off than on again. The CPU will automatically use its standard parameters to boot. You can then enter BIOS Setup again and set up the CPU clock.
If you can’t enter BIOS setup , you must try turning the system on a few times (3~4 times) or press “ INSERT “ key when turn on and the system will automatically use its standard parameters to boot. You can then enter BIOS SETUP again and set up the new parameters.
When you change your CPU:
The motherboard have been designed in such a way that you can turn the system on after having inserted the CPU in the socket without having to configure any jumpers or DIP switches. But if you change your CPU, normally, you just have to turn off the power supply, change the CPU and then, set up the CPU parameters through CPU SOFT MENU™ II. However, if the CPU brand and type is the same, and if the new CPU is slower than the old one, we offer you two methods to successfully complete the CPU change operation.

Chapter 3 |
Method 1: Setup up the CPU for the lowest speed for its brand. Turn the power supply off and change the CPU. Then turn the system on again, and set up the CPU parameters through CPU SOFT MENU™ II.
Method 2: Since you have to open the computer case when you change the CPU, it could be a good idea to use the CCMOS jumper to erase the parameters of the original CPU and to enter BIOS Setup to set up CPU parameters again.
Attention: After setting up the parameters and you leave the BIOS SETUP, and you have verified that the system can be booted, do not press the Reset button or turn off the power supply. Otherwise the BIOS will not read correctly, the parameters will fail and you must enter CPU SOFT MENU™ II again to set up the parameters all over again.
CPU Power Supply:
This option allows you to switch between CPU Default and user define voltage.
³CPU Default: System will detect CPU type and select proper voltage automatically. When it is enabled ,the option “ Core Voltage” will show the current voltage setting that is defined by the CPU and this will not be changeable. We recommend using this CPU default setting and not changing it unless current CPU type and voltage setting can not be detected or not correct.
³User define: This option lets the user select the voltage manually. You can change values of the “ Core Voltage” option lists by using the Page Up and Page Down keys.
Warning: The wrong settings of the multiplier and external clock in certain circumstances may cause CPU damage. Setting the working frequency higher than the PCI chipset or processor specs, may cause abnormal memory module functioning; system hangs; hard disk drive data lose; VGA card abnormal functioning, or abnormal functioning in other add-on cards. Using non-specification settings for your CPU is not the intention of this explanation. These should be used for engineering testing, not for normal applications.

If you use non-specification settings for normal operation, your |
system may |
not be stable, and may effect system reliability. Also, we do not guarantee the stability and compatibility for settings that are not within specification, and any damage of any elements on the motherboard or peripherals, is not our responsibility.

Setup of HDD operating mode NORMAL, LBA, LARGE
Since old operating systems were only able to support HDD whose capacity was not bigger than 528MB, any hard disk with more than 528MB was unusable. AWARD BIOS features a solution to this problem: you can, according to your operating system, choose three operating modes: NORMAL, LBA or LARGE.
Introduction of BIOS |
3-9 |
The HDD auto detection option in the Main Menu will automatically detect
the parameters of your hard disk and the mode supported.
³ Normal mode:
Standard normal mode supports hard disks of 528MB or less. This mode directly uses positions indicated by Cylinders (CYLS), Heads, and Sectors to access data.
³ LBA (Logical Block Addressing) mode:
The earlier LBA mode can support HDDs capacity of up to 8.4GB, and this mode uses a different method to calculate the position of disk data to be accessed. It translates Cylinders (CYLS), Heads and Sectors into a logical address where data are located. The Cylinders, Heads, and Sectors displayed in this menu do not reflect the actual structure of the hard disk, they are just reference values used to calculate actual positions. Currently, all high capacity hard disks support this mode, that’s why we recommend you use this mode. Currently, the BIOS can support INT 13h extension function, then the LBA mode supports hard disk drives capacity exceeding 8.4GB.
³ LARGE Mode:
When the number of cylinders (CYLs) of the hard disk exceeds 1024 and DOS is not able to support it, or if your operating system does not support LBA mode, you should select this mode.
Drive A:
If you have installed the floppy disk drive here, then you can select the type of floppy drive it can support. Six options are available: NoneÎ360K,
5.25 in. Î1.2M, 5.25in. Î720K, 3.5 in. Î1.44M, 3.5 in. Î2.88M, 3.5 in.

FDD supporting 3 Mode:
3 Mode floppy disk drives (FDD) are 3 1/2” drives used in Japanese computer systems. If you need to access data stored in this kind of floppy, you must select this mode, and of course you must have a 3 Mode floppy drive.
Video:
You can select the VGA modes for your video adapter, five options are available: MONOÎEGA/VGA ÎCGA 40ÎCGA 80 ÎBack to MONO. The default setting is EGA/VGA.
Halt On:
You can select which type of error will cause the system to halt. Five options are available: All ErrorsÎNo ErrorsÎAll, But KeyboardÎAll, But DisketteÎAll, But Disk/KeyÎBack to All Errors.
You can see your system memory list in the lower right box, it shows the Base Memory, Extended Memory and Other Memory size in your system.
