2.1.2 Performance

• UltraDMA/66 & UltraDMA/33: Comes with an onboard PCI Bus Master IDE

controller with two connectors that support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/33, PIO Modes 3 & 4 and Bus Master IDE DMA Mode 2, and supports Enhanced IDE devices, such as Tape Backup, CDROM, CD-R/RW, and LS-120 drives.

• 66/100MHz Asynchr onous & 100/100MHz Synchronous Host/DRAM Clock Support: CPU frequency can operate at 66MHz or 100MHz while system

memory operates at 100MHz or 66MHz. This can optimize the VGA performance under shared memory configuration.

• Double or Quadruple the IDE T ransfer Speed: IDE transfers using UltraDMA/ 33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using UltraDMA/66 technology. The best of all is that these new technology is compatible with existing ATA-2 IDE specifications so there is no need to upgrade current IDE devices.

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas- ter buses to memory to CPU.

• SDRAM Optimized Performance: ASUS smart series motherboards support the new generation memory, Synchronous Dynamic Random Access Memory (SDRAM), which increases the data transfer rate to 800MB/s max using PC100 SDRAM.

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also implemented on all ASUS smart series motherboards. ACPI provides more Energy Saving Features for future operating systems (OS) supporting OS Direct Power Management (OSPM) functionality . W ith these features implemented in the OS, PCs can be ready around the clock, yet satisfy all the energy saving standards. To fully utilize the benefits of ACPI, an ACPI-supported OS such as Windows 98 must be used.

• PC’98 Compliant: Both the BIOS and hardware levels of the motherboard meets PC’98 compliancy . The new PC’98 requirements for systems and components are based on the following high-level goals: Support for Plug and Play compatibility and power management for configuring and managing all system components, and 32-bit device drivers and installation procedures for Windows 95/98/NT.

2. FEATURES

2.1.3 Intelligence

• Fan Status Monitoring and Alarm: To prevent system overheat and system

damage, the CPU, power supply, and system fans can be monitored for RPM and failure. All the fans are set for its normal RPM range and alarm thresholds.

• Temperature Monitoring and Aler t: To prevent system overheat and system

damage, this motherboard supports Socket 370 processor thermal sensing.

• 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 will give the user information on managing their limited resources more efficiently.

• 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 to implement silent PC systems.

• Dual Function Power Button: The system can be in one of two states, one is Sleep mode and the other is the Soft-Off mode. Pushing the power button for less than 4 seconds places the system into Sleep mode. When the power button is pressed for more than 4 seconds, it enters the Soft-Off mode.

• Remote Ring On (requires modem): This allows a computer to be turned on remotely through an internal or 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 OS support): Chassis 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.

3.3 Hardware Setup Procedure

Before using your computer, you must complete the following steps:

1. Check Motherboard Settings

2. Install Memory Modules

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

5. Connect Ribbon Cables, Panel Wires, and Power Supply

3.4 Motherboard Settings

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

W ARNING! Computer motherboards and expansion 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.

8) CPU Bus Frequency Setting (DSW1–1,2,3,4)

This option tells the clock generator what frequency to send to the CPU, DRAM, and the AGPset. This allows the selection of the CPU’s Exter- nal frequency. The CPU external frequency multiplied by the CPU Core:External Frequency Multiple equals the CPU’ s Internal frequency (the advertised CPU speed). NOTE: You may set the memory speed independently from the CPU External Frequency. Depending on your memory type PC66 (66MHz) or PC100 (100MHz), select the appropriate “RAM” speed along with the appropriate “CPU” speed.

9) Memory Transfer Mode Setting (DSW1–5)

You can set the memory clock frequency to be in synchronous or asynchronous mode with respect to the CPU external frequency.

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory. This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are

available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac- cess Memory (SDRAM) of either 8, 16, 32, 64, 128MB, or 256MB.

The SiS chipset does not support ECC. However, ECC memory modules may still be used, but the ECC function will not be available.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1

Chip Configuration.

Install memory in any combination as follows:

3.5.1 VGA Shared Memory with DIMM

When using DIMM as shared memory for the onboard VGA, be sure that there is a DIMM inserted into DIMM socket 1.

3.5.2 General DIMM Notes

• For the system CPU bus to operate at 100MHz, use only PC100-compliant DIMMs. When this motherboard operates at 100MHz, most system will not

even boot if non-compliant modules are used because of the strict timing issues involved under this speed. If your DIMMs are not PC100-compliant, set the CPU bus frequency to 66MHz RAM to ensure system stability. NOTE: For motherboards that support asynchronous mode, set the memory bus frequency to 66MHz.

• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability.

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

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

• BIOS shows SDRAM memory on bootup screen.

3.5.3 DIMM Memory Installation

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. DIMM modules are longer and have different pin contact on each side and therefore have a higher pin density. SIMM modules have the same pin contact on both sides.

3.6 Central Processing Unit (CPU)

This motherboard provides a ZIF (Zero Insertion Force) Socket 370. The CPU for your 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! Be sure that there is sufficient air circulation across the processor’s

heatsink by regularly checking that your CPU fan is working. W ithout sufficient circulation, the processor could overheat and damage both the processor and the motherboard. You may install an auxiliary fan, if necessary.

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 angle. Insert the CPU with the correct orientation as shown. The notched corner should point towards the end of the lever . Because the CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation as shown. The picture below is for reference only; you should have a CPU fan that covers the face of the CPU. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, push the socket’ s lever down while holding down the CPU.

NOTE: Do not forget to set the correct Bus Frequency and Multiple for your Socket 370 processor or else your system may start. Socket 370 processors provide internal thermal sensing so that a socket mounted thermal resistor is not needed.

CAUTION: Be careful not to scrape the motherboard when mounting a clampstyle processor fan or else damage may occur to the motherboard.

3.7 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.

3.7.1 Expansion Card Installation Procedure

1. Read the documentation for your expansion card and make any necessary hardware settings for your expansion card, such as jumpers or switches.

2. Remove your computer system’s cover and the bracket plate on the slot you intend to use. Keep the bracket for possible future use.

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

4. Secure the card on the slot with the screw you removed above.

5. Replace the computer system’s cover.

6. Set up the BIOS if necessary (such as IRQ xx Used By ISA: Yes)

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

3.7.2 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, leaving 6 IRQs free for expansion cards. If your motherboard has PCI audio onboard, an extra IRQ will be used, leaving 5 IRQs free. If your motherboard has ISA audio onboard, an extra 3 IRQs will be used, leaving 3 IRQs free.

NOTE: PCI slots 1 and 5 share the same IRQ. Both ISA and PCI expansion cards may require IRQs. System IRQs are available to

cards installed in the ISA expansion bus first, then any remaining IRQs are available to 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. To see a map of your used and free IRQs in Windows 98, the Control Panel icon in My Computer, contains the System icon, which gives you the Device Manager tab. Double-clicking on a specific hardware device gives you the Resources tab which shows the Interrupt number and address. Make sure that no two devices use the same IRQ or your computer will experience problems when those two devices are in use at the same time.

3. H/W SETUP

Expansion Cards

ASUS MES User’s Manual 27

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 INT A.

3.7.3 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 . T o select a DMA channel, see PCI/ PNP ISA DMA Resour ce Exclusion in 4.4.3 PCI Configuration. NOTE: The onboard audio by default uses DMA1.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for

legacy ISA cards (see PCI/PNP ISA IRQ Resource Exclusion and PCI/PNP

ISA DMA Resour ce Exclusionin 4.4.3 PCI Configuration). Choose Yes in IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to

reserve).

3.7.4 ISA Cards and Hardware Monitor

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

3.8 External Connectors

WARNING! Some pins are used for connectors or power sources. These are

clearly distinguished from jumpers in 3.1 Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe on

Pin 1 side of the connector . The four corners of the connectors are labeled on the motherboard. Pin 1 is the side closest to the power connector for hard drives and floppy drives. IDE ribbon cable must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.

1) PS/2 Mouse Connector (6-pin PS2KBMS)

The system will direct IRQ12 to the PS/2 mouse if one is detected. If one is not detected, expansion cards can use IRQ12. See PS/2 Mouse Function Control in 4.4 Advanced Menu.
