This chapter will introduce step by step all the standard equipment and will also present, as completely as possible future upgrade capabilities.
Page 10 Chapter 2 & User friendly instructions Our objective is to enable the novice computer user to perform the installation by themselves. We have attempted to write this document in a very clear, concise and descriptive manner to help overcome any obstacles you may face during installation.
Page 11: Standard External Connectors
Installing the Mainboard ¬ 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 mainboard. 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.
Page 12 Chapter 2 J6 - Hardware Suspend switch There is no specific orientation. Connect the two-thread hardware suspend plug to the J6 connector pins on the mainboard. Since most cases do not support this feature, most of you ignore this instruction. Furthermore, this feature is not necessary as it is already a part of the mainboard.

Page 18: Jumpers And Switches
2-10 Chapter 2 - Jumpers and Switches : Delete the contents of the CMOS This jumper is set on pins 1 and 2 at the factory, in order for the computer to function normally, so please do not change this setting. The main feature of this jumper is to solve situations where the computer crashes due to improper usage.
Page 19: Presentation And Installation Of The Cpu
On other boards, when you want to install the CPU, you have, more or less, to setup some jumpers or DIP switches. With the AR5 mainboard, you will not need to adjust any jumper or switch. The CPU speed and model is set up by software, in order to allow the user to complete setup and installation procedures easily.
Page 20 2-12 Chapter 2 Clock multiplier factor The real operation clock within the CPU is the multiple of the external clock. We refer to this factor as the clock multiplier factor. The four factors possible are 1.5, 2, 2.5 and 3. The factor differs from one CPU to another. For instance, the Intel Pentium 166 CPU has a 66MHz external clock, with a multiplier factor of 2.5, so that the speed of the internal clock is 66MHz x 2.5.
Page 21 Installing the Mainboard 2-13 P-Rating The P-Rating was defined by some manufacturers other than Intel to rate the performance of their CPU in comparison with Intel Pentium CPUs. For instance, Cyrix 6x86 P166+ has a higher actual speed compared with Intel Pentium P166, its internal clock needs only 133MHz versus 166MHz for Intel’...
Page 22: Installing System Memory ¡I Dram Memory ¡J
2-14 Chapter 2 ¯ Installing System Memory DRAM Memory ¡i ¡j When this mainboard was designed, we not only have taken into account the present needs, but we have also tried to care about demands for future upgrades: 1. Two 168-pin DIMM sockets: If you want to extend your memory capacity, you will have no solution other than to use 168-pin 3.3V unbuffered DIMM sockets.
Page 23 ¡i EDO or FP DRAM ¡j, and you cannot use pairs from different “species”. But the AR5 support different “pairs” and use different type of memory modules, notice: l ¡i SIMM1 and SIMM2 ¡j must use the same memory type, as well as ¡i SIMM3 and SIMM4 ¡j.
Page 24 2-16 Chapter 2 ¡i 168-pin DIMM modules specifications ¡j Computer Knowledge According to the standards defined by JEDEC, there are a lot of different types of specifications for 168-pin DIMM sockets.

Page 29: Chapter 3 Introduction Of Bios
Introduction of BIOS Chapter 3 Introduction of BIOS The BIOS is a program located on a Read-Only Memory chip on the mainboard. 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.
Page 30 Chapter 3 Three to five seconds after the message is displayed, if you press the Del key, or if you press simultaneously the Ctrl Alt Esc keys, you will access the BIOS Setup menu. At that moment, the BIOS will display the following message: ROM PCI/ISA BIOS(XXXXXXXX) CMOS SETUP UTILITY...
Page 31: Cpu Setup ¡I Cpu Soft Menu™¡J
Introduction of BIOS ¬ CPU setup ¡i CPU SOFT MENU™ ¡j The CPU can be setup through a programmable switch (CPU SOFT MENU™ ), that replaces traditional manual hardware configuration. This feature allows the user to complete more easily the installation procedures. You can install the CPU without configuring any jumpers or switches.
Page 32 Chapter 3 CPU Operating Speed: This option sets the CPU speed. Different CPU brands use different techniques to indicate the CPU speed. For example, AMD and Cyrix use P- Rating. In this field, the CPU speed is indicated like this: CPU speed (external clock x multiplier factor) Select the CPU speed according the type and the speed of your CPU.
Page 33 When you change your CPU: The AR5 mainboard 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™...
Page 34 Chapter 3 Method 2: Try turning the system on a few times (3~4 times) and the system will automatically use its standard parameters to boot. You can then enter BIOS SETUP again and set up the new parameters. Method 3: Since you have to open the computer case when you change the CPU, it could be a good idea to use the JP6 jumper to erase the parameters of the original CPU and to enter BIOS Setup to set up CPU parameters again.
Page 35 Introduction of BIOS ¤ When the CPU is dual voltage, two options will be displayed to set up Vcore and Vio plane voltage / Core Plane Voltage: ä 2.93v ¡G For AMD K6 and Cyrix 6x86L CPU. ä 2.80v ¡G For Intel Pentium MMX CPUs. ä...
Page 36 Chapter 3 Attention: After setting up the parameters and you leave the BIOS SETUP, and you have verified that the system can be turned on, 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™...

If you do not really understand each of the options in this menu, we recommend you use default values. In each item, you can press <F1> at any time to display all the options for this item.
Page 40: Cpu Internal Cache
3-12 Chapter 3 CPU Internal Cache: This item is used to Enable or to Disable the CPU internal cache. When the cache is set at Disable, it is much slower, so the default setting for this item is Enable. Some old and very bad programs will make the computer malfunction or crash if the system speed is to high.
Page 41: Boot Up Floppy Seek
Introduction of BIOS 3-13 Boot Up Floppy Seek: When computer boots up, the BIOS detects if the system has FDD or not. When this item is enabled, if the BIOS detects no floppy drive, it will display a floppy disk drive error message. If this item is disabled, the BIOS will skip this test.
Page 42: Security Option
3-14 Chapter 3 Security Option: This option can be set to System or to Setup. After you have created a password through PASSWORD SETTING, this option will deny access to your system (System) or modification of computer setup (BIOS Setup) by unauthorized users. ä...
Page 43 Introduction of BIOS 3-15 Shadowing address ranges (C8000-CBFFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address C8000-CBFFF uses the shadow feature or not. If you have no interface card using this memory block, don’ t enable this option.
Page 44 3-16 Chapter 3 Computer SHADOW knowledge What is the SHADOW? The BIOS of standard video or interface cards is stored in ROM, and it is often very slow. With the Shadow feature, the CPU reads the BIOS on the VGA card and copies it into RAM. When the CPU runs this BIOS, the operation is speeded up.
Page 45: Chipset Features Setup Menu
Introduction of BIOS 3-17 ¯ Chipset Features Setup Menu The Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset on the mainboard. Since the parameters of the buffers are closely related to hardware, if the setup is not correct or false, the mainboard will become unstable or you will not be able to boot up.
Page 46 3-18 Chapter 3 Attention:Unless you are very familiar with your computer and with the DRAM configuration and speed, we recommend you not change the DRAM options but enable this option. DRAM settings: The other DRAM settings are all closely related to hardware. If you do not understand this very well, don’...
Page 47: Power Management Setup Menu
Introduction of BIOS 3-19 ° Power Management Setup Menu The difference between Green PCs and traditional computers is that Green PCs have a power management feature. With this feature, when the computer is powered on but inactive, the power consumption is reduced in order to save energy. When the computer operates normally, it is in Normal mode.

Page 77 General Discussion about HDD Installation Appendix E General Discussion about HDD Installation Most of the present HDDs use IDE interface. Installing an IDE hard disk does not require a huge amount of intelligence like installing the driver for a SCSI hard disk, but this means that the user often must install the hard disk by himself and cope with all the problems he may encounter.
Page 78 Appendix E The higher the MODE value is, the best is the hard disk data transfer rate. But this does not mean that you can select the highest mode value as you like. You must be sure that your hard disk supports that type of fast data transfer, otherwise your hard disk will not be able to operate correctly.
Page 79 General Discussion about HDD Installation Installing a hard disk: In the Standard CMOS Setup Menu, Primary means the first connector on the mainboard, that is, connector IDE1 on our mainboard. Secondary means the second connector on the mainboard, that is, connector IDE2 on our mainboard.
