Intelligent Features: 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 (only w/optional hardware monitor): 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 using your 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 (only w/optional hardware monitor): 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 (only w/optional hardware monitor): 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 (only w/optional hardware monitor): 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 (only w/optional hardware monitor): Supports chassis-intrusion monitoring through the optional ASUS CIDB module and Intel LDCM. 10 ASUS P2-99B Users Manual

ASUS Smart Thermal Solutions
(only for motherboards with hardware monitor) 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. III. H/W SETUP CPU 24 To Use the ASUS S-P2FAN See 2. Attach the Heatsink on the preceding page for the relevant procedures. Note that the S-P2FAN comes with a rock arm design for easy FAN/CPU installation.

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 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 PNP AND PCI SETUP) 7. Install the necessary software drivers for your expansion card.
III. H/W SETUP Expansion Cards 26
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 the use of 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 cards 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.
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 a PCI slot that has a card in it that requires 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. 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 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). III. H/W SETUP DMA Channels 27

Assigning DMA Channels for ISA Cards
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.

5. External Connectors

WARNING! Some pins are used for connectors or power sources. These are clearly separated from jumpers in Layout Contents. Placing jumper caps over these will cause damage to your motherboard. IMPORTANT: Ribbon cables should always be connected with the red stripe on Pin 1 side of the connector. The four corners of the connectors are labeled on the motherboard. Pin 1 is the side closest to the power connector on hard drives and some floppy drives. IDE ribbon cables must be less than 18 in. (46 cm), with the second drive connector no more than 6 in. (15 cm) from the first connector. 1. Keyboard Connector (5-pin) This connector supports either a standard IBM-compatible, 101/102-key, or 104key keyboard (Windows 95-compatible).

Details of Power Management Setup
IV. BIOS SETUP Power Management 51 Power Management (User Define) This field acts as the master control for the power management modes. Max Saving puts the system into power saving mode after a brief period of system inactivity; Min Saving is almost the same as Max Saving except that this time the system inactivity period is longer; Disable disables the power saving features; User Define allows you to set power saving options according to your preference. IMPORTANT: Advanced Power Management (APM) should be installed to keep the system time updated when the computer enters suspend mode activated by the BIOS Power Management. For DOS environments, you need to add the statement, DEVICE=C:\DOS\POWER.EXE, in you CONFIG.SYS. For Windows 3.x and Windows 95, you need to install Windows with the APM feature. A battery and power cord icon labeled Power will appear in the Control Panel. Choose Advanced in the Power Management Field. Video Off Option (Suspend -> Off ) This field determines when to activate the video off feature for monitor power management. The settings are Always On and Suspend -> Off.
Video Off Method (DPMS OFF) This field defines the video off features. The following options are available: DPMS OFF, DPMS Reduce ON, Blank Screen, V/H SYNC+Blank, DPMS Standby, and DPMS Suspend. The DPMS (Display Power Management System) features allow the BIOS to control the video display card if it supports the DPMS feature. Blank Screen only blanks the screen (use this for monitors without power management or green features. If set up in your system, your screen saver will not display with Blank Screen selected). V/H SYNC+Blank blanks the screen and turns off vertical and horizontal scanning..... PM Timers This section controls the time-out settings for the Power Management scheme. The fields included in this section are HDD Power Down, which places the hard disk into its lowest power consumption mode, and the Suspend Mode which suspends the CPU. The system automatically wakes up from any power saving mode when there is system activity such as when a key is pressed from the keyboard, or when there is activity detected from the enabled IRQ channels. HDD Power Down (Disable) Shuts down any IDE hard disk drives in the system after a period of inactivity. This time period is user-configurable to 115 Min or Disable. This feature does not affect SCSI hard drives. Suspend Mode (Disable) Sets the period of time after which the susppend mode activates: 30 sec, 1 Min, 2 Min, 4 Min, 8 Min, 20 Min, 30 Min, 40 Min, 1 Hour, and Disable..... Power Up Control This section determines the ways the system can be controlled when it is started or restarted, when modem activity is detected, or when power to the computer is interrupted and reapplied. The Soft-Off mode refers to powering off the system through a momentary button switch (ATX switch) or through the software as opposed to disconnecting the AC power by way of a rocker switch or other means. PWR Button < 4 Secs (Soft Off) When set to Soft Off, the ATX switch can be used as a normal system power-off button when pressed for less than 4 seconds. Suspend allows the button to have a dual function where pressing less than 4 seconds will place the system in sleep mode. Regardless of the setting, holding the ATX switch for more than 4 seconds will power off the system.

Details of PNP and PCI Setup
PNP OS Installed (No) This field allows you to use a Plug-and-Play (PnP) operating system to configure the PCI bus slots instead of using the BIOS. Thus interrupts may be reassigned by the OS when Yes is selected. When a non-PnP OS is installed or to prevent reassigning of interrupt settings, select the default setting of No. IV. BIOS SETUP Plug & Play / PCI 54 Slot 1 / Slot 2 / Slot 3 IRQ (Auto) These fields set how IRQ use is determined for each PCI slot. The default setting for each field is Auto, which uses auto-routing to determine IRQ use. The other options are manual settings of NA, 3, 4, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot. PCI Latency Timer (32 PCI Clock) The default setting of 32 PCI Clock enables maximum PCI performance for this motherboard. IRQ xx Used By ISA (No/ICU) These fields indicate whether or not the displayed IRQ for each field is being used by a legacy (non-PnP) ISA card. Two options are available: No/ICU and Yes. The first option, the default value, indicates either that the displayed IRQ is not used or an ISA Configuration Utility (ICU) is being used to determine if an ISA card is using that IRQ. If you install a legacy ISA card that requires a unique IRQ, and you are not using an ICU, you must set the field for that IRQ to Yes. For example: If you install a legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA to Yes....
DMA x Used By ISA (No/ICU) These fields indicate whether or not the displayed DMA channel for each field is being used by a legacy (non-PnP) ISA card. Available options include: No/ICU and Yes. The first option, the default setting, indicates either that the displayed DMA channel is not used or an ICU is being used to determine if an ISA card is using that channel. If you install a legacy ISA card that requires a unique DMA channel, and you are not using an ICU, you must set the field for that channel to Yes. ISA MEM Block BASE (No/ICU) This field allows you to set the base address and block size of a legacy ISA card that uses any memory segment within the C800H and DFFFH address range. If you have such a card, and you are not using an ICU to specify its address range, select a base address from the six available options; the ISA MEM Block SIZE field will then appear for selecting the block size. If you have more than one legacy ISA card in your system that requires to use this address range, you can increase the block size to either 8K, 16K, 32K, or 64K. If you are using an ICU to accomplish this task, leave ISA MEM Block BASE to its default setting of No/ICU. SYMBIOS SCSI BIOS (Auto) Auto allows the motherboards BIOS to detect whether you have a Symbios SCSI card. If a Symbios SCSI card is detected, the motherboards Symbios BIOS will be enabled; if no Symbios SCSI card is detected, the onboard Symbios SCSI BIOS will be disabled. Disabled will disable the motherboards Symbios SCSI BIOS so that the BIOS on an external Symbios SCSI card can be used. (If your Symbios SCSI card does not have a BIOS, the Symbios SCSI card will not function.) USB IRQ (Enabled) Enabled reserves an IRQ# for the USB to work, Disabled does not allow the USB to have an IRQ# and therefore prevents the USB from functioning. If you are not using any USB devices, you may set this feature to Disabled to save an extra IRQ# for expansion cards. VGA BIOS Sequence (PCI/AGP) You can select the search order for your VGA card(s). PCI/AGP will detect PCI VGA cards before AGP, and AGP/PCI will detect AGP cards before PCI VGA.

After you attempt to wake up a computer, the status of that computer changes in the list view to a Wake Pending status. If the attempt to wake up a computer is successful, the Wake Pending status changes to a status reflecting the computers health (such as Normal, Warning, or Critical). If the computer does not wake up after five minutes, a message box appears stating possible reasons why the computer did not respond. (For example, the computer may be disabled or may not support Wake-OnLAN.) After clicking OK, the Wake Pending status reverts to its original status of Unavailable or Wakeable. NOTE: Your computer must have a Wake-On-LAN network adapter to support this feature. Some computers that support the Wake-On-LAN technology may have remote wakeup disabled in the BIOS by default. Before Client Manager can wake up a remote computer, you will need to enable this option in the BIOS configuration of each remote computer. VI. S/W REFERENCE Intel LDCM 76
Displaying the Properties of a Client Computer
You can display the properties of any discovered client computer even if you cannot otherwise access the computer because of access limitations or Unavailable status. If you display the properties of an unavailable computer, the properties are read from a database in the Windows registry on your computer. Since the Operating System information is not stored in this same database, that information is not available for a computer with a status of Unavailable. Remember that some items may not be current if the properties have changed while the computer was off the network.
When you open the Select Computer dialog box, each computer in the list displays an icon indicating the current status of that computer. The table below describes the seven states a computer may be in. VI. S/W REFERENCE Intel LDCM 77
Understanding the Computer Status Icons
Unavailable Wakeable Wake Pending
The computer is currently in a powered-down state. The computer is currently in a powered-down state but supports Remote Wakeup technology. A temporary status (not to exceed five minutes) while Client Manager attempts to wake up a computer. (A computer that is in the process of booting without having received a wakeup instruction is listed as Unavailable, not Wake Pending.) The computer is operating within normal tolerances. A computer that has exceeded a warning tolerance level. For example, the PC Health indicator can be configured to display a warning icon if a hard disk is running low on space. A computer that has exceeded a critical tolerance level. For example, if the hard disk is running critically low on available space, the PC Health indicator displays a critical icon. A computer that is powered on, but the health status (Normal, Warning, or Critical) is not known. A computer that includes support for mobile PC features, such as mobile battery. Mobile computers display the same array of health icons (above) used for nonmobile computers.

ASUS CIDB Additional Considerations
1. All motherboards with CIDB: If there is no power to the motherboard (i.e. removing the power cord or turning the power supplys switch off) the alarm will not sound but the CIDB will still remember an intrusion event which BIOS and LDCM will detect on the next bootup. 2. Motherboard with chassis intrusion components: Photo sensor, switch, and memory will not operate with power removed. Power is required to send a signal to the motherboards intrusion memory and buzzer. When using the CIDB on these motherboards, all the CIDB functions will be disabled, the motherboards intrusion components must still be used. The CIDB can benefit these motherboards by providing a chassis switch which will operate even when the power is removed. Pins [2-3] of the SW jumper can be used for a momentary toggle switch and the CIDBs battery will be used to send an intrusion signal to the motherboards intrusion memory.
IMPORTANT: Your system must have a VCMOS signal level of exactly 2.5Volts in order to use the S370 CPU card. The optional ASUS S370 CPU card allows Slot 1 motherboards to accept socket 370 processors. The ASUS S370 CPU card gives Slot 1 motherboard owners an inexpensive way to upgrade their Pentium II computers using lower costing socket 370 processors. Since socket 370 processors are based on the Pentium II design, the only difference is the connector and the amount of internal cache within the processor. The following picture shows the ASUS S370 CPU card with a plastic retainer attached to the edge. The retainer is used to hold the ASUS S370 CPU card in place using the motherboards Slot 1 retention mechanism. ASUS S370 CPU Card Retainer VII. APPENDIX ASUS S370 CPU Card 83

The ASUS S370 CPU Card

Slot 1 Compatible Connector

Using the ASUS S370

The general procedure for using the ASUS S370 CPU card: 1. Check the voltage setting for your socket 370 processor using the jumpers on the card if necessary.
