Push the latches on the processor (E) outward until they click into place in the retention mechanism. The latches must be secured for proper electrical connection of the processor.

Fan power cable

l Installing a heat sink and cooling fan is necessary for proper heat
dissipation from your CPU. Failing to install these items may result in overheating and damage of your CPU.
l Please refer to your boxed Pentium II processor installation or
other documentation attached with your CPU for detailed installing instructions.

Installing System Memory

The mainboard provides three 168-pin DIMM sites for memory expansion. The DIMM socket supports 1Mx64(8MB), 2Mx64(16MB), 4Mx64(32MB), 8Mx64(64MB), 16Mx64(128MB), and 32Mx64(256MB) or double sided DIMM modules. Minimum memory size is 8MB and maximum memory size is 384 MB. There are three banks of Memory on the system board. In order to create a memory array, certain rules must be followed. The following set of rules allows for optimum configurations.
l The memory array is 64 or 72 bits wide. (Without parity or with parity) l Those modules can be populated in any order. l Support single and double density DIMMS.
The following is the valid memory configuration: Bank Memory Module Bank0 8MB,16MB, 32MB,64MB, 2 (DIMM1) 128MB Bank1 8MB,16MB, 32MB,64MB, 2 (DIMM2) 128MB Bank3 8MB,16MB, (DIMM3) 32MB,64MB, 128MB 1 Total System Memory = Total Memory 8MB ~ 128MB 8MB ~ 128MB 8MB ~ 128MB 8MB ~ 384MB
If DRAM module size will increase in the feature , the supported memory size will increase as well according to the available DRAM module on the market.

Introduction of BIOS

Chapter 3
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. Its main function is to manage the setup of the mainboard 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 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.

M Dont 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, configurations 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 to system stability, and to ensure that your system performs at its best. After the BIOS has achieved the auto-diagnostic and autodetection 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:

BIOS Setup main menu

In the BIOS Setup main menu of Figure 3, 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: l Press Esc to quit the BIOS Setup. l Press (up, down, left, right) to choose, in the main menu, the option you want to confirm or to modify. l Press F10 when you have completed the setup of BIOS parameters to save these parameters and to exit the BIOS Setup menu. l Press Page Up/Page Down or +/- keys when you want to modify the BIOS parameters for the active option. Computer knowledge CMOS DATA Maybe you have heard somebody saying that their CMOS 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 in 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.
CPU Setup i CPU SOFT MENUj
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. The CPU must be setup according its specifications. In the first option, you can press <F1> at any time to display all the items that can be chosen for that option.

Fig 3-1 CPU Name Is: Intel Pentium II MMX

CPU SOFT MENU

CPU Operating Speed:
This option sets the CPU speed. 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. i Note 1 j For Intel Pentium II MMX CPUs, you can choose the following settings: 233 (66x3.5) 266 (66x4) 300 (66x4.5) 333 (66x5) i Note 4 j User define external clock and multiplier factor: User Define / External Clock: 66MHz 75MHz 83MHz / Multiplier Factor: You can choose the following multiplier factors: 2.0 2.5 3.0 3.5 4.0 4.5 5.0 However, differences will exist because of the various brands and types available. 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. / 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. It is a very important tool for test units to verify CPU stability. Do not use this feature. Disable: CPU external clock is operating within the normal limits. Enable: CPU external clock is operating within the limits of the Turbo mode.
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 cant enter BIOS setup , you must 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. When you change your CPU: The mainboard have been designed in such a way that you can turn the system on after having inserted the CPU in the slot 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. 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. 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. 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.

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.
2 For further information about HDD installation, refer to Appendix B.

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.

Fig 3-3

BIOS Features Setup

Virus Warning:

This item can be set as Enable or Disable. When this feature is enabled, if there is any attempt from a software or an application to access the boot sector or the partition table, the BIOS will warn you that a boot virus is attempting to access to the hard disk.

CPU Level 1 Cache:

This item is used to Enable or to Disable the CPU level 1 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. In that case, you should Disable this feature.

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.
Quick power on self test:
After the computer has been powered on, the BIOS of the mainboard will run a series of tests in order to check the system and its peripherals. If the Quick power on self test feature is Enable, the BIOS will simplify the test procedures in order to speed up the boot process. The default is Enable.

Boot Sequence:

When the computer boots up, it can load the operating system from floppy drive A:, hard disk drive C:, SCSI disk drive or CD-ROM. There are many options for the boot sequence: A, C, SCSI C, A, SCSI C, CD-ROM, A CD-ROM, C, A D, A, SCSI (at least 2 IDE HDD can be used) E, A, SCSI (at least 3 IDE HDD can be used) F, A, SCSI (at least 4 IDE HDD can be used) SCSI, A, C SCSI, C, A A, SCSI, C LS/ZIP, C

Swap Floppy Drive:

This item can be set as Enable or Disable. When this feature is enabled, you dont need to open the computer case to swap the position of floppy disk drive connectors. Drive A: can be set as drive B:, and drive B: can be set as drive A:.

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.

OS Select For DRAM > 64MB:
When the system memory is bigger than 64MB, the communication method between the BIOS and the operating system will differ from one operating system to another. If you use OS/2, select OS2; if you choose another operating system, select Non-OS2.
Report No FDD For WIN 95 :
When using Windows 95 without floppy drive , please set this item to Yes

Video BIOS Shadow:

This option is used to define whether the BIOS on the video card uses shadow feature or not. You should set this option to Enable, otherwise the display performance of the system will greatly decrease.
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, dont enable this option.
Shadowing address ranges (CC000-CFFFF Shadow):
This option allows you to decide if the memory block (BIOS) of an interface card at the address CC000-CFFFF uses the shadow feature or not. If you have no interface card using this memory block, dont enable this option.
Shadowing address ranges (D0000-D3FFF Shadow):
This option allows you to decide if the memory block (BIOS) of an interface card at the address D0000-D3FFF uses the shadow feature or not. If you have no interface card using this memory block, dont enable this option.
Shadowing address ranges (D4000-D7FFF Shadow):
This option allows you to decide if the memory block (BIOS) of an interface card at the address D4000-D7FFF uses the shadow feature or not. If you have no interface card using this memory block, dont enable this option.
Shadowing address ranges (D8000-DBFFF Shadow):
This option allows you to decide if the memory block (BIOS) of an interface card at the address D8000-DBFFF uses the shadow feature or not. If you have no interface card using this memory block, dont enable this option.
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, dont enable this option. Computer knowledge SHADOW 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.
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. If you dont know the hardware very well, use default values (use the LOAD SETUP DEFAULTS option).

Fig 3-4

Chipset Features Setup
You can use the arrow keys to move between the items. Use "PgUP", "PgDn", "+" and "-" to change the values. When you have finished setting up the chipset, press "ESC" to go back to the main menu.

Auto Configuration:

This option allows (Enable) or prevents (Disable) the BIOS from using default values for Auto Configuration. The BIOS default is Enable. When you select Enable, the BIOS will automatically use the values related to DRAM. You will not be able to set up the following options. When you select Disable, you can manually set up DRAM options.
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, dont make any changes. Our BIOS is able to auto detect the characteristics of your DRAM and to choose the best settings.

Memory Hole At 15M-16M:

This option is used to free up the 15M-16M memory block. Some special peripherals need to use a memory block located between 15M and 16M, and this memory block has a size of 1M. We recommend that you disable this option. There are small differences in the chipset feature setup according to different mainboard models, but this has no influence upon performance. Our default setup should be the best one. That is the reason why we do not describe all the features of this menu.
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. In this mode, the Power Management Program will control the access to video, parallel ports, serial ports and drives, and the operating status of the keyboard, mouse and other device. These are referred to as Power Management Events. In cases where none of these events occur, the system enters the power saving mode. When one of the controlled events occurs, the system immediately returns to normal mode and operates at its maximum speed. Power saving modes can be divided into three modes according to their power consumption: Doze Mode, Standby Mode , and Suspend Mode. The four modes proceed in the following sequence: Normal Mode===> Doze Mode===> Standby Mode===> Suspend Mode

Resources Controlled By:

When you select Auto, the BIOS will automatically assign the IRQ and DMA to PCI / ISA PnP. When this option is Manual, you can choose which IRQ or DMA can assign to PCI / ISA PnP.
PCI IDE Card 2nd Channel:
This option can be enabled or disabled. BIOS default is Enable. Since this channel uses IRQ15, if you want to use this channel, you have to enable this option to make the BIOS assign IRQ15 to this channel.

PCI IDE Card IRQ Map to:

Three options are available for this item: PCI Auto, PCI-slotX and ISA. PCI-Auto: The onboard BIOS auto-detects which PCI slot has an IDE card inserted in. PCI-slotX: Some old PCI IDE cards cannot be detected by the BIOS. If the onboard BIOS cannot detect a PCE IDE card, you have to specify on which PCI slot the IDE card is inserted, to make the BIOS assign IRQ14 for use by the interrupt number (INT#) of this PCI slot. ISA: If you select ISA, it means that your PCI IDE card features a paddleboard and a cable that can be connected to IRQ on the ISA slot, because the BIOS will not assign any IRQ to this PCI slot. Attention:Primary Channel and Secondary Channel : The BIOS needs two independent interrupt number (INT#) lines to be allocated to the PCI IDE card. Be careful not to choose twice the same interrupt number (INT#).

Assign IRQ for PCI VGA :

You can assign IRQ for PCI VGA or not.

On Board FDD Controller:

This is to Enable or Disable the Onboard FDD Controller.

On board Serial Port 1:

This is used to specify the I/O address and IRQ of Serial Port 1. Ten options are available: Disable, 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4 or 2E8/IRQ3.3F8/IRQ10, 2F8/IRQ11, 3E8/IRQ10, 2E8/IRQ11, and AUTO.

On board Serial Port 2:

This is used to specify the I/O address and IRQ of Serial Port 2. Ten options are available: Disable, 3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4 or 2E8/IRQ3. 3F8/IRQ10, 2F8/IRQ11, 3E8/IRQ10, 2E8/IRQ11, and AUTO. / Onboard IR function: Three options are available: IrDA (HPSIR)mode. ASK IR (Amplitude Shift Keyed IR)mode. Disabled. / IR Tr/Re Polarity : Set IR transmission/reception polarity as High or Low.

On board Parallel Port:

Set the I/O address and IRQ of the onboard parallel port. Four options are available: Disable, 3BC/IRQ7, 278/IRQ5 and 378/IRQ7. Default is 378/IRQ7. / Parallel Port Mode: Can be set as ECP, EPP, PS2, ECP+EPP, or Normal (SPP) mode. Default is Normal (SPP) mode. / ECP Mode Use DMA: When the mode selected for the onboard parallel port is ECP, the DMA channel selected can be Channel 1 or Channel 3. / EPP Mode Select: When the mode selected for the onboard parallel port is EPP, two EPP version options are available: EPP1.7 or EPP1.9.
On board IDE-1 Controller:
Onboard PCI IDE 1 controller can be set as Enable or Disable. / Master drive Mode: Auto: the BIOS can auto-detect the transfer mode of the HDD in order to set its data transfer rate. (Default) PIO Mode 0 ~ 4: User can specify the PIO mode of the HDD in order to set its data transfer rate. / Slave drive Mode: Auto: the BIOS can auto-detect the transfer mode of the HDD in order to set its data transfer rate.

Y o u might o ften hear abo ut the PIO mo de, M aster mo de o r D M A mo de o f H D D. T hese mo des reflect the w ay data is transferred fro m and to the ID E drive and the mainbo ard. W hat is the PIO mo de? W hen the system needs to access hard disk data, the C PU delivers input/o utput (I/O ) o rders thro ugh the chipset o n the mainbo ard to the hard disk drive, and than puts these data into the system memo ry. T his is the PIO mo de. W hat is the M aster mo de? W hen the system needs to access hard disk data, these data are directly accessed fro m the hard disk by the chipset o n the mainbo ard (using a D M A o r a PIO mo de), and then the data is put into the memo ry. In this case, the C PU do es no t participate in the data transfer. W hat is the D M A mo de? U sually, D M A mo de refers to accessing the hard disk data by the chipset, it do es no t refers to data transfer mo de. H ere are so me examples o f data transfer rates fo r ID E H D D w ith PIO interface: PIO M o de 0 T he fastest data transfer rate reaches 3.3M byte/sec PIO M o de 1 T he fastest data transfer rate reaches 5.2M byte/sec PIO M o de 2 T he fastest data transfer rate reaches 8.3M byte/sec PIO M o de 3 T he fastest data transfer rate reaches 11.1M byte/sec PIO M o de 4 T he fastest data transfer rate reaches 16.6M byte/sec

Installing two HDDs: The red line on the connection cable m us t be lined up with pin 1 on the connector.
M etho d 1: Set the hard disk drive used fo r bo o t up at M aster, and the o ther drive at Slave. C o nnect o ne o f the co nnecto rs o f the 40-pin cable to the first drive, ano ther co nnecto r to the seco nd drive, and the o ther end o f the cable to co nnecto r ID E 1 o n the mainbo ard. M etho d 2: Set the hard disk drive used fo r bo o t up at M aster, co nnect o ne end o f the 40-pin cable to the drive, and the o ther end to co nnecto r ID E 1 o n the mainbo ard. Set the o ther hard disk drive at M aster, co nnect o ne end o f the 40-pin cable to the drive, and the o ther end to co nnecto r ID E 2 o n the mainbo ard.
Installing two HDDs + one CD-ROM drive:
M etho d 1: Set the hard disk drive used fo r bo o t up as M aster, set the o ther H D D at Slave, co nnect o ne co nnecto r o f the 40-pin cable to the first drive, ano ther co nnecto r to the seco nd drive, and the o ther end o f the cable to co nnecto r ID E 1 o n the mainbo ard. Y o u can igno re the setting o f the C D -R O M drive. C o nnect o ne end o f the 40-pin cable to the drive, and the o ther end to co nnecto r ID E 2 o n the mainbo ard. W e reco mmend yo u use this metho d, w hich has no influence o n H D D speed. M etho d 2: Set the hard disk drive used fo r bo o t up at M aster, co nnect o ne end o f the 40-pin cable to the drive, and the o ther end to co nnecto r ID E 1 o n the mainbo ard. Set the o ther hard disk drive at M aster, and be sure that the C D -R O M drive is set at Slave. M o st o f C D -R O M drives are set at Slave as a default, so yo u w ill no rmally no t have to set the C D -R O M drive. After yo u have verified the settings, co nnect o ne co nnecto r o f the 40-pin cable to the H D D , ano ther co nnecto r to the C D -R O M drive, and the o ther end o f the cable to co nnecto r ID E 2 o n the mainbo ard.
Installing three H D D s:
M etho d 1: Set the hard disk drive used fo r bo o t up at M aster, set the seco nd drive at Slave. C o nnect o ne co nnecto r o f the 40-pin cable to the first drive, ano ther co nnecto r to the seco nd drive, and the o ther end o f the cable to co nnecto r ID E 1 o n the mainbo ard. Set the o ther (the third) drive at M aster, and co nnect o ne end o f the 40-pin cable to the drive, and the o ther end to co nnecto r ID E 2 o n the mainbo ard. M etho d 2: Set the hard disk drive used fo r bo o t up at M aster, and co nnect o ne end o f the 40-pin cable to the drive and the o ther end to co nnecto r ID E 1 o n the mainbo ard. Set ano ther drive (the seco nd drive) at M aster and the third drive at Slave, co nnect o ne co nnecto r o f the 40-pin cable to the seco nd drive, ano ther co nnecto r to the third drive, and the o ther end o f the cable to co nnecto r ID E 2 o n the mainbo ard.
