II. FEATURES

Features of the ASUS P2-99 Motherboard

The ASUS P2-99 is carefully designed for the demanding PC user who wants advanced features processed by the fastest CPU.

Specifications:

Multi-Speed: Supports Intel Pentium® III (450MHz and faster), Pentium® II (233MHz to 450MHz), and CeleronTM (266MHz and faster) processors.

Intel AGPset: Features Intel’s 440ZX AGPset with I/O subsystems and front-side bus (FSB) platform, which boosts the traditional 66MHz internal bus speed to 100MHz.

Multi-Cache: Supports processors with either 512, 256, 128, or 0KB Pipelined Burst Level 2 cache.

PC100 Memory Support: Equipped with two DIMM sockets to support Intel PC100-compliant SDRAMs (8, 16, 32, 64, 128, or 256MB) up to 512MB. These new SDRAMs are necessary to meet the critical enhanced 100MHz bus speed requirement.

Peripheral Wake Up: Supports modem wake up, keyboard wake up, and LAN card wake up functions from sleep or soft-off mode.

Thermal Sensor Connector w/Optional Sensor (only w/hardware monitor): Accurately detects the CPU temperature with the ASUS Smart Fan or the Intel boxed processor heatsink with fan when connected to an optional ASUS P2T-Cable.

PC Health Monitoring (optional): Provides an easier way to examine and manage system status information such as CPU and system voltages, temperatures, and fan status through the onboard hardware monitor ASIC and the bundled LDCM by Intel or PC Probe from ASUS.

AGP Slot: Supports an Accelerated Graphics Port card for high performance, component level interconnect targeted at 3D graphical display applications using a 1X or 2X mode bus.

SB-Link™ Connector: Features Creative’s SB-Link™, allowing SB16 compatibility, using Intel’s PC-PCI DMA and serialized IRQ protocols, to AWE64D or compatible PCI audio cards.

SMBus: Features the System Management Bus interface, which is used to physically transport commands and information between SMBus devices.

PCI & ISA Expansion Slots: Provides four 32-bit PCI and three 16-bit ISA slots.

Multi-I/O: Provides two high-speed UART compatible serial ports and one parallel port with EPP and ECP capabilities. UART2 can also be directed from COM2 to the Infrared Module for wireless connections.

UltraDMA/33 Bus Master IDE: Comes with an onboard PCI Bus Master IDE controller with two connectors that support four IDE devices in two channels, supports UltraDMA/33, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 2, and supports Enhanced IDE devices, such as Tape Backup and CD-ROM, CD-R, CD-RW, and LS-120 drives.

ASUS P2-99 User’s Manual

II.FEATURES

Universal Retention Mechanism: Supports a Pentium® III / II processor packaged in a Single Edge Contact Cartridge (SECC/SECC2) or a CeleronTM processor packaged in a Single Edge Processor Package (SEPP).

Wake-On-LAN Connector: Supports Wake-On-LAN activity through an optional ASUS PCI-L101 10/100 Fast Ethernet PCI card (See APPENDIX) or a similar ethernet card.

IrDA: Supports an optional infrared port module for a wireless interface.

Special Features:

Enhanced ACPI and Anti-Boot Virus BIOS: Features a programmable BIOS, offering enhanced ACPI for Windows 98 compatibility, built-in firmware-based virus protection through Trend ChipAway Virus codes, and autodetection of most devices for virtually automatic setup.

Desktop Management Interface (DMI):Supports DMI through BIOS, which allows hardware to communicate within a standard protocol creating a higher level of compatibility. (Requires DMI-enabled components.)

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’98 Compliant: Both the BIOS and hardware levels of ASUS smart series of motherboards meet PC’98 compliancy.

II. FEATURES

Intelligent Features (only with optional hardware monitor):

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 setting (see Power Management Setup under BIOS SETUP). 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.

Keyboard Power Up:Keyboard Power Up can be enabled or disabled to allow the computer to be powered on by pressing the space bar on the keyboard.

Message LED (requires ACPI OS support):Turbo 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.

Remote Ring On (requires external modem): This allows a computer to be turned on remotely through an external modem. With this benefit on-hand, any user can access vital information from their computer 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: To prevent system overheat and system damage, there are heat sensors to monitor the CPU (the Pentium III / II processor requires a special heatsink with a thermal sensor) and system temperatures to warn of damaging temperatures.

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 optional ASUS CIDB module and Intel LDCM.

2.Keyboard Power Up Setting (KBPWR)

This allows you to disable or enable the keyboard power up function. Set to Enable if you want to use your keyboard (by pressing <Spacebar>) to power up your computer. This feature requires an ATX power supply that can supply at least 300mA on the +5VSB lead. The default is set to Disable because not all computers have the appropriate ATX power supply. Your computer will not function if you set this to Enable and if you do not have the right ATX power supply.

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.

8 chips/side modules do not support ECC, only 9 chips/side modules support ECC.

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

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.

ASUS provides two smart solutions to Slot 1 CPU thermal problems: the ASUS Smart Fan or ASUS S-P2FAN and the ASUS P2T-Cable.

ASUS S-P2FAN

The optional ASUS Smart Fan or ASUS S-P2FAN is a CPU fan for a Pentium® II processor packaged in an SECC. Unlike other CPU thermal solutions, the ASUS S-P2FAN has an integrated thermal sensor located near the center of the CPU heat source. The sensor is optimized by ASUS to give the most accurate reading of the CPU temperature, thus provides the best protection to your computer system.

Cards Expansion

III.HARDWARE SETUP

4.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.

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 PNP AND PCI SETUP)

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

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.

Both ISA and PCI expansion cards may require to use 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. You may use the Microsoft Diagnostics (MSD.EXE) utility located in the Windows directory to see a map of your used and free IRQs. If you use Windows 95, the Resources tab under Device Manager displays the resource settings being used by a particular device (to gain access, double-click the System icon under the Control Panel program). Ensure that no two devices share the same IRQs or your computer will experience problems when those two devices are in use at the same time.

26

ASUS P2-99 User’s Manual

III. HARDWARE SETUP

To simplify this process, this motherboard has complied 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 PCI cards that require 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.

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. You can select a DMA channel in the PCI and PnP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy ISA cards (under PNP AND PCI SETUP of the BIOS SETUP, choose Yes in IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

ISA Cards and Hardware Monitor

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

Accelerated Graphics Port (AGP)

This motherboard provides an accelerated graphics port (AGP) slot to support a new generation of graphics cards with ultra-high memory bandwidth, such as an ASUS 3D Hardware Accelerator.
