Performance	2. FEATURES

2.FEATURES

2.1.2Special Features

•ACPI Ready: Advanced Configuration and 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.

•Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings

as an alternative to leaving the computer ON and QuickStart™ so that you do not have to wait for a long time for system bootup.

•New Compliancy: Both the BIOS and hardware levels of this motherboard meet the stringent requirements for PC 99 certification The new PC 99 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 . Color-coded connectors and descriptive icons make identification easy as required by PC 99.

•Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through the onboard SYMBIOS firmware.

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/66 Bus Master IDE can handle rates up to 66.6MB/s. This motherboard with its chipset and support for UltraDMA/100 increases the data transfer rate to 100MB/s. UltraDMA/100 is backward compatible with DMA/66, 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 and UltraDMA/100 require a 40-pin 80-conductor cable to be enabled.)

•VCM/SDRAM Optimized Performance: This motherboard supports a new generation memory, NEC’s 64Mb Virtual Channel Memory (VCM) Synchronous Dynamic Random Access Memory (SDRAM), which is compatible to the industry standard SDRAM. The VCM’s core design provides up to 50% higher SDRAM speed at reduced power consumption of about 30%. This motherboard also supports standard SDRAM, which increases the data transfer rate (1.064GB/s max using PC133-compliant SDRAMs and 800MB/s max using PC100-compliant SDRAMs).

10	ASUS A7V User’s Manual

2.FEATURES

2.1.4Intelligence

•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.

•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: 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.

•Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC 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.

3.3Hardware 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

6.Setup the BIOS Software

3.4Motherboard Settings

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

WARNING! 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.

5.Ensure that the ATX power supply is switched off before you plug in or remove the ATX power connector on the motherboard.

WARNING! Make sure that you unplug your power supply when adding or removing system components. Failure to do so may cause severe damage to your motherboard, peripherals, and/or components. The onboard LED when lit acts as a reminder that the system is in suspend or soft-off mode and not powered OFF.

3.5System Memory (DIMM)

This motherboard uses only Dual Inline Memory Modules (DIMMs). Three 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 1.5GB. One side (with memory chips) of the DIMM takes up one row on the motherboard. This motherboard also supports NEC’s Virtual Channel (VC) SDRAMs.

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 PC133 SDRAMs with VCM SDRAMs.

Install memory in any combination as follows:

DIMM Location	168-pin DIMM	Total Memory
Socket 1 (Rows 0&1)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1
Socket 2 (Rows 2&3)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1
Socket 3 (Rows 4&5)	SDRAM 8, 16, 32, 64, 128, 256, 512MB	x1
	Total System Memory (Max 1536MB)	=

3.5.1 General DIMM Notes

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

• For the system CPU bus to operate at 100 MHz/133MHz, use only PC100-/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, 256MB; double-sided come in 32, 64, 128, 256, 512MB.

WARNING! Be sure that the DIMM you use can handle the specified SDRAM MHz or else bootup will not be possible.

WARNING! Make sure that you unplug your power supply when adding or removing memory modules or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards (see 3.3 Hardware Setup Procedure for more information).

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 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.

The notches on the DIMM will shift between left, center, or right to identify the type and also to prevent the wrong type from being inserted into the DIMM slot on the motherboard. You must tell your retailer the correct DIMM type before purchasing. This motherboard supports four clock signals per DIMM.

26	ASUS A7V User’s Manual

3.HARDWARE SETUP

3.6Central Processing Unit (CPU)

The motherboard provides a Socket 462 or Socket A for CPU installation. The CPU that came with the motherboard should have a fan and heatsink attached to it to prevent overheating. If this is not the case, then purchase and install a set before you turn on your system.

WARNING! Make sure that the heatsink is mounted tightly against the processor. Make sure also that there is sufficient air circulation across the processor’s heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard. You may install an auxiliary fan, if necessary. A thermal sensor cable is bundled with this motherboard to help in monitoring the CPU temperature.

To install a CPU, first turn off your system and remove its cover. Locate the Socket 462 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 be orientated toward the blank space on the socket nearest 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 is for reference only; you should have a CPU fan and heatsink that covers the face of the CPU. With the added weight of the CPU fan and heatsink, no force is required to insert the CPU. Once completely inserted, close the socket’s lever while holding down the CPU.

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency multiple setting is available only on unlocked processors) for your processor or else boot-up may not be possible. Socket A processors require a socket mounted thermal resistor. This motherboard comes bundled with an ASUS P2T thermal sensor cable (see next page for installation procedures).

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

3.7.2Assigning 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.

The following table lists the default IRQ assignments for standard PC devices. Use this table when configuring your system and for resolving IRQ conflicts.
