busses to the memory and processor.

ASUS A7V266-EX User’s Manual

2. FEATURES

2.1.3 Intelligence

• Auto Fan Off: The system fans powers 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 and system fans can be monitored for RPM and failure. All fans are set for its normal RPM range and alarm thresholds.

• Power LED (requir es ACPI OS support): The power LED indicates the system

status.

• 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 anywhere.

Intelligence

2. FEATURES

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

ASUS ASIC through the CPU’s internal thermal diode (on Pentium III and Celeron) 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.

3.3 Hardware Setup Procedure

Complete the following steps before using your computer:

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 cables

6. Configure the BIOS parameter settings

3.4 Motherboard Settings

This section tells you how to change motherboard function settings through the switches and/or jumpers.

W ARNING! Computer motherboards and expansion cards contain very delicate

Integrated Circuit (IC) chips. To avoid damaging them due to static electricity, follow these precautions whenever you work on your computer.

1. Unplug the computer when working on the internal components.

2. Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling computer components.

3. Hold components by the edges and try not to touch the IC chips on them.

4. Whenever you uninstall any component, place the components on a grounded antistatic pad or in the bag that came with the components.

5. Before you install or remove any component, ensur e that the A TX power

supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard,

peripherals, and/or components. (TIP: When lit, the onboard LED indicates that the system is in suspend or soft-off mode, not powered OFF. See illustration below.)

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 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.
