Series Smart

II.FEATURES

•Auto Fan Off:The system fans will power off automatically even in sleep mode. This function reduces both energy consumption and system noise, and is an important feature in implementing silent PC systems.

•Dual Function Power Button (requires ATX power supply):Pushing the power button for less than 4 seconds when the system is in the working state places the system into one of two states: sleep mode or soft-off mode, depending on the BIOS setting (see Power Management Setup under BIOS SETUP). When the power button is pressed for more than 4 seconds, the system enters the soft-off mode regardless of the BIOS setting.

•Keyboard Power Up: Keyboard Power Up can be enabled or disabled to allow the computer to be powered on by pressing the keyboard’s spacebar.

•Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable current to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management.

•System Resources Alert: Today’s operating systems, such as Windows 95/98/ NT and OS/2, require much more memory and hard drive space to present enormous user interfaces and run large applications. The system resource monitor will warn the user before the system resources are used up to prevent possible application crashes. Suggestions on managing the user’s limited resources more efficiently are provided.

•CPU Slow Down:When CPU fans or system fans malfunction, the system will deactivate the CPU Clock line to decrease CPU utilization to the speed upon detection of system overheat. This will prevent CPU damage from system overheat. The CPU utilization will restore normal operations when temperature falls below a safe level.

•Remote Ring On (requires external modem):This feature allows a computer to be turned on remotely through an external modem. With this benefit on hand, any user can access vital information from their computer from anywhere in the world!

•Message LED (requires ACPI-supported OS): Turbo LEDs now act as information providers. Through the way a particular LED illuminates, the user can determine the stage the computer is in. A simple glimpse provides useful information to the user.

1. Motherboard Settings

This section explains how to change your motherboard’s function settings through the use of switches and/or jumpers.

WARNING! Computer motherboards, baseboards and components, such as SCSI cards, contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer.

1.Unplug your computer when working on the inside.

2.Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case.

3.Hold components by the edges and try not to touch the IC chips, leads or connectors, or other components.

4.Place components on a grounded antistatic pad or on the bag that came with the component whenever the components are separated from the system.

Jumpers

1.VGA Interrupt Selection (VIRQ) / 2. VGA Setting (VEN_DIS)

VIRQ allows you to set the VGA interrupt method. The default enables the chipset’s internal interrupt routing. VEN_DIS allows you to enable or disable the onboard VGA. Disable the onboard VGA if you are using a VGA card on the expansion slot.

2.System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of either 8, 16, 32, 64, 128MB, or 256MB to form a memory size between 8MB and 768MB. One side (with memory chips) of the DIMM takes up one row on the motherboard.

To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip) and make the proper settings through “Chipset Features Setup” in BIOS setup.

Memory speed setup is recommended through SDRAM Configuration under “Chipset Features Setup” in BIOS setup.

IMPORTANT (see Notes below)

• To make using bus speeds ³95MHz possible, SDRAMs used must be compatible with the current Intel PC100 SDRAM specification..

Install memory in any combination as follows:

DIMM Location	168-pin DIMM		Total Memory
DIMM1 (Rows 0&1)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
DIMM2 (Rows 2&3)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
DIMM3 (Rows 4&5)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
	Total System Memory (Max 768MB)	=

NOTES

•DIMMs that have more than 18 chips are not supported on this motherboard.

•To make using bus speeds ³95MHz possible, use only PC100-compliant

DIMMs. Most systems will not even boot if non-compliant modules are used because of the strict timing issues involved with speeds ³95MHz.

•Two possible memory chips are supported: SDRAM with and without ECC.

ECC is not supported when using bus speeds ³83MHz .

•SDRAM chips are generally thinner and have higher pin density than EDO (Extended Data Output) chips.

•BIOS shows SDRAM memory on bootup screen.

•8 chips/side modules do not support ECC, only 9 chips/side modules support ECC.

•Single-sidedDIMMs are available in 16, 32, 64, 128MB; double-sided in 32, 64, 128, 256MB.

DIMM Memory Installation Procedures:

Insert the module(s) as shown. Because the number of pins are different on either side of the breaks, the module will only fit in the orientation as shown. DRAM SIMM modules have the same pin contacts on both sides. SDRAM DIMMs have different pin contacts on each side and therefore have a higher pin density.

3.Central Processing Unit (CPU)

The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible with ZIF Socket 5 processors. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case then purchase a fan before you turn on your system.

WARNING! Without a fan circulating air on the CPU, the CPU can overheat and cause damage to both the CPU and the motherboard.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree right angle. Insert the CPU with the correct orientation as shown. Use the notched corner of the CPU with the white dot as your guide. The white dot should point towards the end the of the lever. Notice that there is a blank area where one hole is missing from that corner of the square array of pin holes and a “1” printed on the motherboard next to that corner. Because the CPU has a corner pin for three of the four corners, the CPU will only fit in the one orientation as shown. The picture is for reference only; you should have a CPU fan that will cover the face of the CPU. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, hold down on the fan and close the socket’s lever.

IMPORTANT: You must set jumpers for “CPU to BUS Frequency Ratio” and jumpers for “BUS Frequency Selection” depending on the CPU that you install.

4.Expansion Cards

WARNING! Make sure that you unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.

Expansion Card Installation Procedure:

1.Read your expansion card documentation on any hardware and software settings that may be required to setup your specific card.

2.Set any necessary jumpers on your expansion card.

3.Remove your computer system’s cover.

4.Remove the bracket on the slot you intend to use. Keep the bracket for possible future use.

5.Carefully align the card’s connectors and press firmly.

6.Secure the card on the slot with the screw you removed in step 4.

7.Replace the computer system’s cover.

8.Setup the BIOS if necessary

(such as “IRQ xx Used By ISA: Yes” in PNP AND PCI SETUP)

9.Install the necessary software drivers for your expansion card.

Assigning IRQs for Expansion Cards

Some expansion cards need to use an IRQ to operate. Generally an IRQ must be exclusively assigned to one use. In a standard design there are 16 IRQs available but most of them are already in use by parts of the system which leaves 6 free for expansion cards.

Both ISA and PCI expansion cards may need to use IRQs. System IRQs are available to cards installed in the ISA expansion bus first, and any remaining IRQs are then used by PCI cards. Currently, there are two types of ISA cards.

The original ISA expansion card design, now referred to as “Legacy” ISA cards, requires that you configure the card’s jumpers manually and then install it in any available slot on the ISA bus. You may use Microsoft’s Diagnostic (MSD.EXE) utility included in the Windows directory to see a map of your used and free IRQs. For Windows 95 users, the “Control Panel” icon in “My Computer,” contains a “System” icon, which gives you a “Device Manager” tab. Double clicking on a specific device give you “Resources” tab which shows the Interrupt number and address. Make sure that no two devices use the same IRQs or your computer will experience problems when those two devices are in use at the same time.

Cards Expansion

III. HARDWARE SETUP

To simplify this process, this motherboard complies with the Plug and Play (PNP) specification which was developed to allow automatic system configuration whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available.

If the system has both Legacy and PNP ISA cards installed, IRQs are assigned to PNP cards from those not used by Legacy cards. The PCI and PNP configuration of the BIOS setup utility can be used to indicate which IRQs are being used by Legacy cards. For older Legacy cards that do not work with the BIOS, you can contact your vendor for an ISA Configuration Utility.

An IRQ number is automatically assigned to PCI expansion cards after those used by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI slot that has a card in it that requires an IRQ. To install a PCI card, you need to set something called the INT (interrupt) assignment. Since all the PCI slots on this motherboard use an INTA #, be sure that the jumpers on your PCI cards are set to INTA.

Assigning DMA Channels for ISA Cards

Some ISA cards, both legacy and PnP, may also need to use a DMA (Direct Memory Access) channel. DMA assignments for this motherboard are handled the same way as the IRQ assignment process described earlier. You can select a DMA channel in the PCI and PnP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy ISA cards (under PNP AND PCI SETUP of the BIOS SOFTWARE, choose Yes in IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

ISA Cards and Hardware Monitor

The onboard hardware monitor uses the address 290H-297H, so legacy ISA cards must not use this address or else conflicts will occur.
