2.1.2 Special Features

ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more Energy Saving Features for operating systems that support OS Direct Power Management (OSPM) functionality. With 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. Easy Installation: Incorporates BIOS that supports autodetection of hard disk drives, PS/2 mouse, and Plug and Play devices to make the setup of hard disk drives, expansion cards, and other devices virtually automatic. PC98 Compliant: Both the BIOS and hardware levels of ASUS smart series motherboards meet PC98 compliancy. The new PC98 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 Windows95/98/NT. Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through the onboard SYMBIOS firmware.

2. FEA TURES Performance

2.1.3 Performance Features
Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master busses to the memory and processor. High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus Master IDE can handle rates up to 33MB/s. This motherboard with its chipset and support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to 66.6MB/s. UltraDMA/66 is backward compatible with both DMA/33 and DMA and with existing DMA devices and systems so there is no need to upgrade current EIDE/IDE drives and host systems. (UltraDMA/66 requires a 40-pin 80-conductor cable to be enabled and/or for UltraDMA Mode 4.) SDRAM Optimized Performance: Supports the new generation memory - Synchronous Dynamic Random Access Memory (SDRAM) which increases the data transfer rate to 1066MB/s max using PC133-compliant SDRAM.

2.1.4 Intelligence

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: 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 or OS setting (see PWR Button < 4 Secs in 4.5 Power Menu). When the power button is pressed for more than 4 seconds, the system enters the soft-off mode regardless of the BIOS setting. 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 fans are set for its normal RPM range and alarm thresholds. PS/2 Keyboard/Mouse Power Up: Keyboard/Mouse Power Up can be enabled or disabled to allow the computer to be powered on by either pressing the space bar, Ctrl-Esc, or Power keys (see 4.5.1 Power Up Control). Message LED (requires ACPI OS support): Turbo LEDs now act as information providers. Through the way a particular LED illuminates, the user can determine if there are messages waiting in the mailbox. A simple glimpse provides useful information to the user. 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, users can access vital information from their computers from anywhere in the world! System Resources Alert: Todays 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. Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC through the CPUs internal thermal diode (on Pentium III, Pentium II (Deschutes), and PPGA370 Celeron in conjunction with the ASUS S370-D or S370-L CPU card) to prevent system overheat and system damage. Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable voltage to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management. Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the ASUS ASIC. A chassis intrusion event is kept in memory on battery power for more protection.

3.5 System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). Four sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory size between 8MB to 2GB. One side (with memory chips) of the DIMM takes up one row on the motherboard. This motherboard also supports NECs Virtual Channel (VC) SDRAMs and Enhanced Memory Systems High-speed DRAMs (HSDRAMs). Memory speed setup is recommended through 4.4.1 Chip Configuration. IMPORTANT (see General DIMM Notes below for more) SDRAMs used must be compatible with the current Intel PC133 SDRAM specification. DO NOT attempt to mix registered SDRAMs with VC SDRAMs.
3. H/W SETUP System Memory
Install memory in any combination as follows:
DIMM Location Socket 1 (Rows 0&1) Socket 2 (Rows 2&3) Socket 3 (Rows 4&5) Socket 4 (Rows 6&7) 168-pin DIMM SDRAM 8, 16, 32, 64, 128, 256, 512MB SDRAM 8, 16, 32, 64, 128, 256, 512MB SDRAM 8, 16, 32, 64, 128, 256, 512MB SDRAM 8, 16, 32, 64, 128, 256, 512MB Total System Memory (Max 2GB) x1 x1 x1 x1 = Total Memory
General DIMM Notes DIMMs that have more than 18 chips are not supported on this motherboard. For the system bus to operate at 100MHz, use only PC100- or PC133-compliant DIMMs; for the system bus to operate at 133MHz, use PC133-compliant DIMMs. ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability. SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips. BIOS shows SDRAM memory on bootup screen. Single-sided DIMMs come in 16, 32, 64,128, or 256MB; double-sided come in 32, 64, 128, 256, or 512MB.
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.

Make sure the heatsink is mounted tightly against the SECC2, SECC, or SEPP; otherwise, the CPU will overheat. You may install an auxiliary fan to provide adequate circulation across the processors passive heatsink.
3.6.3 Installing the Universal Retention Mechanism
Your motherboard comes with a set of Universal Retention Mechanism (URM), which supports Pentium III / II and Celeron processors. There are two types of URMs: (A) With Integrated Retainer Pins and (B) With Separate Retainer Pins. URM (A) URM (B)

2. 3. 4.

Separate Retainer Pins Integrated Retainer Pins Place the motherboard on the anti-static foam that was shipped with the motherboard. Do not place the motherboard on a hard surface while installing the URM as the black fastener sleeves must protrude through the bottom of the motherboard. Locate the Slot 1 connector on the motherboard. Position the retention mechanism on either side of the Slot 1 connector. Making sure that the top retainer pins are not pushed in, press down on the retention brackets until the black fastener sleeves fit snugly against the board.
WARNING! Installing the URM while the retainer pins are pushed in will not only cause the URM to be installed improperly but will also damage the URM. 5. Push the four retainer pins completely down into the black fastener sleeves until the head of each pin is securely seated.
3.6.4 Installing the Processor
NOTE: The following steps assume that you have already attached the heatsink and installed the URM into your motherboard. 1. Make sure that the processor substrate key is aligned with the Slot 1 connector key.

3.7 Expansion Cards

WARNING! 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 or software settings for your expansion card, such as jumpers. 2. Remove your computer systems cover and the bracket plate on the slot you intend to use. Keep the bracket for possible future use. 3. Carefully align the cards connectors and press firmly. 4. Secure the card on the slot with the screw you removed above. 5. Replace the computer systems cover. 6. Set up the BIOS if necessary (such as IRQ xx Used By ISA: Yes in 4.4.3 PCI Configuration) 7. Install the necessary software drivers for your expansion card.
3.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need 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 additional IRQ will be used. If your motherboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free. IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support Share IRQ or that the cards do not need IRQ assignments. Conflicts will arise between the two PCI groups that will make the system unstable or cards inoperable.

10. Chassis/CPU/Power Supply Fan Connectors (3-pin CHA_,CPU_,PWR_FAN) These connectors support cooling fans of 500mA (6W) or less. Orientate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fans plug to the board taking into consideration the polarity of the this connector. NOTES: The Rotation signal is to be used only by a specially designed fan with rotation signal. The fans have been designed to power off after entering the sleep/soft-off mode. This is to reduce both energy consumption and system noise. WARNING! The CPU and/or motherboard will overheat if there is no airflow across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers, do not place jumper caps over these pins.

The ASUS S370 Series CPU cards support both Coppermine and Celeron processors to give Slot 1 motherboard owners an inexpensive way to upgrade their Pentium II/III computers using lower costing socket 370 processors. Since socket 370 processors are designed on the Pentium II/III design, the only difference is the package form factor. Additionally, the S370 Series CPU cards can acquire temperature data from the processors thermal diode and send it to the motherboard that supports CPU thermal monitoring. The following are pictures of the ASUS S370 Series CPU cards with black plastic retainers attached to the edges. The retainers are used to hold the ASUS S370 Series CPU cards in place using the motherboards Slot 1 retention mechanisms. ASUS S370-133 CPU Card (standard model)

AGP (Accelerated Graphics Port) An interface specification that enables high-performance 3D graphics on mainstream PCs. AGP offers a higher throughput than PCI by providing the graphics controller with direct access to system memory. Bus PCI AGP 1X AGP 2X AGP 4X Bus Frequency 33MHz 66MHz 133MHz 266MHz Bus Speed
AUTOEXEC.BAT AUTOEXEC.BAT is a special-purpose file that is automatically executed by DOS whenever the computer is turned ON or restarted. This file contains important commands that help configure the system to work with certain software and devices. Windows 95 and later has its own startup files and may not use or may ignore parts of the AUTOEXEC.BAT file. BIOS (Basic Input/Output System) BIOS is a set of routines that affect how the computer transfers data between computer components, such as memory, disks, and the display adapter. The BIOS instructions are built into the computers read-only memory. BIOS parameters can be configured by the user through the BIOS Setup program. The BIOS can be updated using the provided utility to copy a new BIOS file into the EEPROM. Bit (Binary Digit) Represents the smallest unit of data used by the computer. A bit can have one of two values: 0 or 1. Boot Boot means to start the computer operating system by loading it into system memory. When the manual instructs you to boot your system (or computer), it means to turn ON your computer. Reboot means to restart your computer. When using Windows 95 or later, selecting Restart from Start | Shut Down. will reboot your computer. Bus Master IDE PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and waiting for mechanical events. Bus master IDE transfers data to/from the memory without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk drives are required to support bus master IDE mode. Byte (Binary Term) One byte is a group of eight contiguous bits. A byte is used to represent a single alphanumeric character, punctuation mark, or other symbol.

COM Port COM is a logical device name used by to designate the computer serial ports. Pointing devices, modems, and infrared modules can be connected to COM ports. Each COM port is configured to use a different IRQ and address assignment. CPU (Central Processing Unit) The CPU, sometimes called Processor, actually functions as the brain of the computer. It interprets and executes program commands and processes data stored in memory. Currently, there are socket 370 (for Pentium Celeron-PPGA), socket 7 (for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III), and slot 2 (for Xeon) processors. Device Driver A device driver is a special set of instructions that allows the computers operating system to communicate with devices such as VGA, audio, ethernet, printer, or modem. DOS (Disk Operating System) DOS is the foundation on which all other programs and software applications operate, including Windows. DOS is responsible for allocating system resources such as memory, CPU time, disk space, and access to peripheral devices. For this reason, DOS constitutes the basic interface between you and your computer. Hardware Hardware is a general term referring to the physical components of a computer system, including peripherals such as printers, modems, and pointing devices. IDE (Integrated Drive Electronics) IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/ 33 IDE devices can achieve up to 33MB/Sec transfer. LPT Port (Line Printer Port) Logical device name reserved by DOS for the computer parallel ports. Each LPT port is configured to use a different IRQ and address assignment. MMX A set of 57 new instructions based on a technique called Single Instruction, Multiple Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX instructions are designed to accelerate multimedia and communications applications, such as 3D video, 3D sound, video conference. PCI Bus (Peripheral Component Interconnect Local Bus) PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard widely used by expansion card manufacturers. Peripherals Peripherals are devices attached to the computer via I/O ports. Peripheral devices allow your computer to perform an almost limitless variety of specialized tasks.
