Specifications	2.FEATURES

2.FEATURES

2.1.2Special 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.

•Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings (average of 5 watts) as an alternative to leaving the computer ON and QuickStartTM so that you do not fall asleep waiting for system bootup (Suspend-to-RAM requires OS support and does not support ISA cards; ISA cards may fail to work coming out of STR mode).

•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.

•PC’99 Compliant: Both the BIOS and hardware levels of ASUS smart series motherboards meet PC’99 compliancy. 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.

•Double the IDE Transfer Speed: ASUS smart series motherboards with Intel chipsets improve IDE transfer rate using Bus Master UltraDMA/33 IDE which can handle data transfers up to 33MB/s.

•SDRAM Optimized Performance: Supports the new generation memory - Synchronous Dynamic Random Access Memory (SDRAM) which increases the data transfer rate to 800MB/s max using PC100-compliant SDRAM.

10	ASUS P3B-F 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.

•PS/2 Keyboard/Mouse Power Up: Keyboard/Mouse Power Up can be enabled or disabled to allow the computer to be powered on by pressing the space bar on the keyboard or moving the mouse.

•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 through the CPU’s 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.

3.5System 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 Access Memory (SDRAM). 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 4.4.1 Chip Configuration.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1 Chip Configuration.

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, 256MB	x1
Socket 2 (Rows 2&3)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
Socket 3 (Rows 4&5)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
Socket 4 (Rows 6&7)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
	Total System Memory (Max 1024MB)	=

NOTE: At the time this User’s Manual was written, 256MB DIMMs are only available as double-sided registered memory.

3.5.1 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.

•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.

•Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64, 128, 256MB.

3.6.5Precautions

Operating a processor at temperatures above its maximum specified operating temperature will shorten the processor lifetime and may cause unreliable operation. To prevent system overheat and/or damage, it is important to have accurate temperature readings of the processor core (the main source of power dissipation) for system thermal management. Included inside Pentium III, Pentium II (Deschutes), and PPGA370 Celeron processors is a thermal sensor that is connected to the internal thermal diode.

Unlike other motherboards, this motherboard was designed to acquire thermal data directly from the processor thermal diode. Therefore, the CPU temperature reported may be higher than those from motherboards that take readings from thermal sensors external to the processor. This is not a cause for alarm. If, however, the BIOS and/or your hardware monitoring program is reporting a CPU temperature above the threshold, check the following:

1.An Intel recommended fan heatsink is used.

2.Good quality thermal interface material is used.

3.The heatsink is correctly installed onto the processor with a strong retention clip.

4.There is no visible gap between the processor die and heatsink.

The thermal interface material should be continuous with no through-holes or debris.

3.7Expansion 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 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 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.

*These IRQs are usually available for ISA or PCI devices.

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 a System icon, which gives you a Device Manager tab. Double-clicking on a specific hardware device gives you the Resources tab which shows the Interrupt number and address. Double-click Computer to see all the interrupts and addresses for your system. 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.
