Installing the Motherboard (1) Installing the Motherboard to the Casing Most computer cases 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.
Chapter 2 (2) 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.

Introduction of BIOS 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.
Page 30
Chapter 3 Fig 3-1 BIOS Setup main menu 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: "...
Introduction of BIOS ™ (1) CPU Setup【 【 【 【 CPU SOFT MENU II】 】 】 】 The CPU can be setup through a programmable switch (CPU SOFT ™ MENU II), 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. In this field, the CPU speed is indicated like this: CPU speed = External clock * Multiplier factor Select the CPU speed according the type and the speed of your CPU. 【Note 1】For Intel Pentium II MMX CPUs, you can choose following settings:...
Page 33
Introduction of BIOS ✏ ✏ ✏ ✏ Turbo Frequency: This item will only be displayed if your CPU external clock supports Turbo mode. The Turbo mode allows you to speed up the external clock by approximately 2.5%. This feature is used to verify the design flexibility.
Page 34
Chapter 3 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.
Page 35
Introduction of BIOS CPU Power Supply: This option allows you to switch between CPU Default and user define voltage. ➤ ➤ ➤ ➤ CPU Default: System will detect CPU type and select proper voltage automatically. When it is enabled ,the option “Core Voltage”...

Fig 3-3 Standard CMOS Setup Menu Date (mm:dd:yy): You can set the date information in this item, month (mm), date (dd) and year (yy).
Page 37
Introduction of BIOS The HDD auto detection option in the Main Menu will automatically detect the parameters of your hard disk and the mode supported. ➤ 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.
Page 38
3-10 Chapter 3 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.
Introduction of BIOS 3-11 (3) BIOS Features Setup Menu BIOS Features Setup Menu has already been set for maximum operation. 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.
3-12 Chapter 3 CPU Level 2 Cache: This item is used to enable or to disable the CPU level 2 cache. When the external cache is enabled, the system works faster. The default is Enable. CPU Level 2 Cache ECC Checking: This item is used to enable or to disable the CPU level 2 cache ECC checking function .
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.
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. ➤...

Page 44
3-16 Chapter 3 Shadowing address ranges (DC000-DFFFF Shadow): This option allows you to decide if the memory block (BIOS) of an interface card at the address DC000-DFFFF uses the shadow feature or not. If you have no interface card using this memory block, don’t enable this option.
Introduction of BIOS 3-17 (4) Chipset Features Setup Menu The Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset on the motherboard. Since the parameters of the buffers are closely related to hardware, if the setup is not correct or false, the motherboard will become unstable or you will not be able to boot up.
3-18 Chapter 3 Auto Configuration: Two options are available: Enabled or Disabled, the default setting is Enabled. The DRAM and cache related to timing are set to 60ns by default but also according to the CPU type and clock. If you choose the Disabled setting, then you can specify your own DRAM timing.
Introduction of BIOS 3-19 *EDO DRAM Write Burst: This option will let you to set the timing for burst mode writes to EDO DRAM. You can think of this as a write request from the CPU which needs four separate parts to finish it. The first, provides the writing location within the DRAM.
3-20 Chapter 3 16 Bit I/O Recovery Time: Five options are available: NA $ 4 $ 1 $ 2 $ 3 $ . This Back to NA option specifies the length of a delay inserted between consecutive 16 bit I/O operations.
Introduction of BIOS 3-21 SDRAM RAS Precharge Time: Two options are available: Slow or Fast. This option specifies the length of the RAS precharge part of the DRAM system memory access cycle when SDRAM system memory is installed. The default setting is Slow. SDRAM CAS latency Time: Two options are available: 2 and 3.
3-22 Chapter 3 (5) 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.

3-24 Chapter 3 Video Off After: Select the saving mode in which the video is switched off. ➤ The video will never be switched off in no power saving mode. ➤ Suspend The video will only be switched off in Suspend mode. ➤...
Introduction of BIOS 3-25 Suspend Mode: When the setting selected for "Power Management" is "User Define", you can define for this mode any delay from 1 minute to 1 hour. If no power management event occurs during this time period, meaning the computer is inactive during this period, the system will enter the Suspend power saving mode.
Page 54
3-26 Chapter 3 PM Timer Events: When one of the specific occurs, the count down made for entry in power saving mode goes back to zero. Since the computer will enter a power saving mode only after an inactivity delay specified (time specific for Doze, Standby and Suspend modes) and after it has no activity, during this time period, any event will cause the computer to re-count the time elapsed.
Page 55
Introduction of BIOS 3-27 ➤Floppy Disk: If any floppy disk I/O activity occurs, it will cause the computer to re- count the time elapsed. ➤Serial Port: If any serial port I/O activity occurs, it will cause the computer to re- count the time elapsed.
3-28 Chapter 3 (6) PNP, PCI & Onboard I/O Setup In this menu, you can change the INT# and IRQ of the PCI bus and the onboard I/O device, I/O port address and other hardware settings. Fig 3-7 PNP, PCI & Onboard I/O Setup Force Update ESCD: If you want to clear ESCD data next time you boot up, and ask the BIOS to reset the settings for the Plug &...

General Discussion about HDD Installation Appendix B General Discussion About HDD Installation Most of the present HDDs use IDE interface. Installing an IDE hard disk does not require a lot of knowledge 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 they may encounter.
Page 72
Appendix B 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.
