2. FEATURES

2.1.3 Performance

• UltraPerformance: Onboard Ultra160/Ultra2 (depending on model) dual chan-

nel SCSI controller with two connectors that support 30 Ultra160/Ultra2 SCSI
devices in two channels.

• Dual Speeds: CPU frequency can operate at either 133MHz or 100MHz de-

pending on the CPU installed.

• High-Speed Data Transfer Interface: SCSI transfers using Ultra160/Ultra2

(depending on model) dual channel SCSI controller can handle rates up to 160MB/
s or 80MB/s. Ultra160/Ultra2 is backward compatible with slower SCSI de­vices so that older SCSI devices are not wasted. (Ultra160/Ultra2 SCSI cables
have twisted pairs compared to flat ribbon cables used in older SCSI standards.)

busses and increases options for intelligent IO and Server Management cards.

• SDRAM Optimized Performance: This motherboard supports PC133 “regis-

tered” Synchronous Dynamic Random Access Memory (SDRAM), which increases
the data transfer rate to 1064MB/s max

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting OS Direct Power
Management (OSPM) functionality . W ith 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.

• New Compliancy: Both the BIOS and hardware levels of the motherboard meet

the stringent requirements for SDG2.0 certification. The new SDG2.0 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 W indows NT/2000. Color-coded connectors and descriptive icons
make identification easy as required by PC 99.

2.1.4 Intelligence

• 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 the fans are set for its normal RPM range and alarm thresholds.

• T emperature Monitoring and Alert: T o prevent system overheat and system dam-

age, this motherboard supports processor thermal sensing and auto-protection.

• Voltage Monitoring and Alert: System voltage levels are monitored to ensure

stable current to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.

• System Resources Alert: Today’s server operating systems, such as Windows

NT and Windows 2000, require much more memory and hard drive space to
present enormous user interfaces and run large applications. The onboard hard­ware ASUS ASIC in conjunction Intel LDSM 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.

• Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see ATX
Power / Soft-Off Switch Lead in 3.8 Connectors for more information) button.
Regardless of the setting, pushing the power button for more than 4 seconds will
enter the Soft-Off mode.

• 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 any information from their computers from anywhere in the world.

• Alert-on-LAN II (requires optional hardwar e component): Part of W ired for
Management to enable IT staff to remotely respond to and resolve system trouble
which will decrease down time and lower total cost of ownership. Remote man­agement response via remote diagnostics and troubleshooting work even when
the operating system has frozen. Remote power down for power management.
Asset tracking and monitoring through features like presence ping and logoff
notification.

256Mbit “registered” SDRAMs with ECC. This motherboard only operates using
synchronous data transfers to the memory . When you use a processor with 100MHz
FSB, it will require that the memory supports 100MHz. When you use a proces-

sor with 133MHz FSB, it will require that the memory supports 133MHz or
else bootup may not be possible.

3.5.2 DIMM Installation

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. DIMMs are
longer and have different pin contacts on each side and therefore have a higher pin
density compared to SIMMs.

The DIMMs must be 3.3V “registered” for this motherboard. T o determine the DIMM
type, check the notches on the DIMMs (see figure below).

The notches on the DIMM module 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 ask your retailer the correct DIMM type before pur­chasing.

3.6 Central Processing Unit (CPU)

The motherboard provides a ZIF Socket 370. The CPU that came with the mother­board should have a fan attached to it to prevent overheating. If this is not the case,
then purchase a fan before you turn on your system.

WARNING! Be sure that there is sufficient air circulation across the processor’s

heatsink by regularly checking that your CPU fan is working. W ithout sufficient
circulation, the processor could overheat and damage both the processor and the
motherboard. You may install an auxiliary fan, if necessary. The CPU will be

unstable if the heatsink is not properly mounted. Double check the contact.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket 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 point towards the end of 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 that covers the
face of the CPU. W ith the added weight of the CPU fan, no force is required to insert
the CPU. Once completely inserted, close the socket’s lever while holding down the
CPU. Next, install an Intel recommended fan heatsink. Locate the CPU fan connector
(see 3.1 Motherboard Layout or 3.8 Connectors) and connect the CPU fan cable to it.

3. H/W SETUP

NOTE: The correct Bus Frequency and Multiple for your Socket 370 processor is
automatically set by this motherboard. Socket 370 processors provide internal ther­mal sensing so that a socket mounted thermal resistor is not needed.

CAUTION! Be careful not to scrape the motherboard when mounting a clamp-

style processor fan or else damage may occur to the motherboard.

3.7.2 Assigning IRQs for Expansion Cards

This is applicable only when MPS 1.4 Support is Disabled in section 4.6 Boot Menu.

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.

3.8 Connectors

WARNING! Some pins are used for connectors or power sources. These are

clearly distinguished from jumpers in the Motherboard Layout. Placing jumper
caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe to

Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connec­tor on hard drives and CD-ROM drives, but may be on the opposite side on
floppy disk drives. Check the connectors before installation because there may
be exceptions. IDE ribbon cable must be less than 46 cm (18 in.), with the sec­ond drive connector no more than 15 cm (6 in.) from the first connector.

UltraDMA/33 master device. It is recommended that non-UltraDMA/33 devices
be connected to the secondary IDE connector . If you install two hard disks, you
must configure the second drive to Slave mode by setting its jumper accord­ingly . Refer to your hard disk documentation for the jumper settings. BIOS now
supports specific device bootup (see Boot Sequence in 4.6 Boot Menu). (Pin

20 is removed to prevent inserting in the wrong orientation when using
ribbon cables with pin 20 plugged). If you have more than two UltraDMA/33

devices, you will need to purchase another UltraDMA/33 cable.
TIP: You may configure two hard disks to be both Masters with two ribbon

cables – one for the primary IDE connector and another for the secondary IDE
connector . You may install one operating system on an IDE drive and another on

a SCSI drive and select the boot disk through Boot Sequence in 4.6 Boot Menu.
