2.1 The ASUS CUBX Motherboard
The ASUS CUBX is carefully designed for the demanding PC user who wants ad-
vanced features processed by the fastest CPU.
2.1.1 Specifications
•Latest Intel Processor Support
Intel Pentium
®
III 100MHz FSB Coppermine core FC-PGA
Intel Celeron™66MHz FSB Mendocino PPGA
•Intel AGPset: Features Intel’s 440BX AGPset with I/O subsystems and front-side
bus(FSB)platform,whichbooststhetraditional66MHzexternalbusspeedto100MHz.
•JumperFree™Mode:Allows processor settings and easy overclocking of fre-
quency and Vcore voltage all through BIOS setup when JumperFree™mode is
enabled. Easy-to-use DIP switches instead of jumpers are included to allow
manual adjustment of the processor’s external frequency.
•Anti-Boot Virus BIOS: Features a programmable BIOS, offering enhanced
Advanced ConfigurationPower Interface (ACPI) support forWindows 98 com-
patibility, built-infirmware-basedvirusprotection throughTrend ChipAwayVirus
codes, and autodetection of most devices for virtually automatic setup.
•PC100 Memory Support: Equipped with four DIMM sockets to support Intel
PC100-compliant SDRAMs (8, 16, 32, 64, 128, or 256MB) up to 1 GB. These
new SDRAMs are necessary to meet the critical enhanced 100MHz bus speed
requirement.
•Peripheral Wake Up: Supports modem, PS/2 keyboard, PS/2 mouse, and LAN
card wake up functions from sleep or soft-off mode.
•PC Health Monitoring: 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 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 us-
ing a 1X or 2X mode bus.
•PCI/ISAExpansionSlots:Providesoptionsofsix32-bitPCI (rev 2.2) expansion
slots with one ISA or six PCI with no ISA, depending on territory. PCI supports
up to 133MB/s maximum throughput.

•UltraDMA/66 & UltraDMA/33 Bus Master IDE: Comes with an onboard
CMD UltraDMA/66 IDE controller with two connectors that support four
UltraDMA/66IDEdevicesintwochannels.SupportsUltraDMA/66,UltraDMA/
33, PIO Modes 3 and 4, and Bus Master IDE DMA Mode 2, as well as Enhanced
IDE devices, such as Tape Backup, CD-ROM, CD-R/RW, and LS-120 drives.
Two additional IDE connectors are onboard that support four UltraDMA/33 IDE
devices. A total of 8 IDE devices can be connected.
•Wake-On-LAN Connector: Supports Wake-On-LAN activity through an op-
tionalASUS PCI-L101 10/100 Fast Ethernet PCI card (see 7.1 PCI-L101 LAN
Card) or a similar ethernet card.
•Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings
as an alternative to leaving the computer ON and QuickStart™so that you do
not have to wait for a long time for system bootup (see Suspend-to-RAM Ca-
pability in 4.5 Power Menu for more information).

2.1.2 Special 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.
•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.
•NewCompliancy:Both the BIOS and hardware levels of this motherboard meet
the stringent requirements for PC’99 certification. The new PC’99 requirements
for systems and components are based on the following high-level goals: Sup-
port for Plug and Play compatibility and power management for configuring
and managing all system components, and 32-bit device drivers and installation
proceduresforWindows 95/98/NT. Color-codedconnectorsanddescriptive 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 mas-
ter busses to the memory and processor.
•High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus
Master IDE can handle rates up to 33MB/s. This motherboard with a CMD
UltraDMA/66 IDE controller and support for UltraDMA/66 doubles the
UltraDMA/33 burst transfer rate to 66.6MB/s. UltraDMA/66 is backward com-
patible with both DMA/33 and DMA and with existing DMA devices and sys-
tems so there is no need to upgrade current EIDE/IDE drives and host systems.
(UltraDMA/66 requires a 40-pin 80-conductor cable to be enabled and/or for
UltraDMA Mode 4.)
•SDRAMOptimizedPerformance:Supportsthenewgenerationmemory-Syn-
chronous Dynamic RandomAccess Memory (SDRAM) which increases the data
transfer rate to 800MB/s max using PC100-compliant SDRAM.

2.1.4 Intelligence
•Dual Function Power Button: Pushing the power button for less than 4 sec-
onds 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.
•Message LED (requiresACPI OS support):Turbo LEDs now act as informa-
tion providers. Through the way a particular LED illuminates, the user can de-
termine if a message has been received from a fax/modem. A simple glimpse
provides useful information to the user.
•Remote Ring On (requires modem): This allows a computer with this mother-
board to be turned on remotely through an internal or external modem. With this
feature, users can access 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 enor-
mous 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.
•Voltage Monitoring andAlert: 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.

3. HARDWARE SETUP
3.3 Hardware Setup Procedure
Before using your computer, you must complete the following steps:
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
6. Setup the BIOS Software
3.4 Motherboard Settings
This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.
WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips.To protect them against damage from static electric-
ity, you should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you
do not have one, touch both of your hands to a safely grounded object or to
a metal object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or
connectors, or other components.
4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

WARNING! Using a higher voltage may help when overclocking but may result
in the shortening of your computer component’s life. It is highly recommended
that you leave this setting on its default.
3) AGP Bus Frequency Setting (DSW Switch 6)
Thisoptionsetsthefrequency ratiobetweentheAGPbus frequency and the DRAM
(CPU bus) frequency. The default sets the AGP bus frequency to be 2/3 of the
DRAM frequency. When the CPU/DRAM frequency is set to 66MHz, set this
switch to [ON]. See the processor table on the next page.

4) CPU External Frequency Selection (DSW Switches 7-10)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
the PCI bus.Thisallowstheselectionofthe CPU’sExternal frequency(orBUSClock).
The BUS Clock multiplied by the Frequency Multiple equals the CPU’s Internal fre-
quency (the advertised CPU speed).
