AMD® Athlon™/ Duron™ Processor Support: Supports AMD’s new socket-
A Palomino™ / Thunderbird™ processor cores.
•
North Bridge System Chipset: ALi M1647™ chipset with AGP/PCI/Memory
controller supports a 133/100MHz Front Side Bus (FSB), supports DDR SDRAM
DIMM, complies with AGP 2.0 specifications for 4X, 2X and 1X AGP modes
and PCI 2.2. bus interface. It is optimized to deliver enhanced AMD Athlon™

support up to 2GB of DDR SDRAM and three SDR DIMM sockets to support
up to 3GB of SDR SDRAM. DDR SDRAM is the newest memory standard with
the highest bandwidth and lowest latency currently available and dramatically
improves the memory system’s ability to service, among others, high multimedia
requirements. (Caution: Do not use DDR & SDRAM modules simultaneously.)
•
•
Stepless Frequency Selection: Allows CPU external (FSB) frequency settings
to be set in 1MHz-increments or reduction.
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.

level interconnection targeted at 3D graphical applications supporting 133MHz
4X mode.
UltraDMA/100 Support: Comes with an onboard PCI Bus Master IDE con-
troller with two connectors that support four IDE devices on two channels. Sup-
ports UltraDMA/100, UltraDMA/66, UltraDMA/33, PIO Modes 3 & 4 and Bus
Master IDE DMA Mode 2, and Enhanced IDE devices, such as DVD-ROM,
CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.

2. FEATURES
•
•
USB: Supports up to six USB ports, two on the back panel and four midboard,
for more peripheral connectivity options.
One Touch Management: Supports an optionalASUS iPanel, an easy to access
box with system information LED display, front I/O ports, and space reserved
for a hard disk drive. With an ASUS iPanel, you can monitor your computer
system’s vital components.
•
PC Health Monitoring: Provides an easy way to examine and manage system
status information, such as CPU and systerm voltages, temperatures, and fan
status through the onboard hardware ASUS ASIC and the bundled ASUS PC
Probe.
•
•
SMBus: Features the System Management Bus interface, which is used to physi-
cally transport commands and information between SMBus devices.
PCI/AMR Expansion Slots: Provides five 32-bit PCI (Rev. 2.2) expansion
slots, which can support Bus Master PCI cards, such as SCSI or LAN cards (PCI
supports up to 133MB/s maximum throughput), and one Audio Modem Riser
(AMR) slot (shared), which supports a very affordable audio and/or modem
riser card.
•
•
Super Multi-I/O: Provides two high-speed UART compatible serial ports and
one parallel port with EPP and ECP capabilities.
Enhanced ACPI & Anti-Boot Virus Protection: Programmable BIOS (Flash
EEPROM), offering enhanced ACPI for Windows 982000/Millenium
compatibility, built-in firmware-based virus protection, and autodetection of most
devices for virtually automatic setup.
•
•
Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to the memory and processor.
Smart BIOS: 2Mb firmware provides Vcore and CPU/SDRAM frequency ad-
justments, boot block write protection, and HD/SCSI/MO/ZIP/CD/Floppy boot
selection.
•
•
•
Integrated Infrared (IrDA) Support: Integrated IR supports an optional re-
mote control package for wireless interfacing with external peripherals, per-
sonal gadgets, or an optional remote controller.
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.)
Color-coded Connectors: To enhance user accessibility to system components
and to meet PC 99 compliancy, major connectors in this motherboard are color-
coded.
2.1.2 Optional Components
•
Onboard Audio: C-Media Audio Chip CMI8738 supporting the latest PCI 6
channel and HRTF 3D Audio sound circuitry.
ASUS A7A266 User’s Manual

2. FEATURES
2.1.3 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
98/2000/Millenium 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.
New Compliancy: 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
procedures for Windows95/98/NT . Color-coded connectors and descriptive icons
make identification easy as required by PC 99.
2.1.4 Performance Features
•
High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus
Master IDE can handle rates up to 33MB/s. This motherboard with its chipset
and support for UltraDMA/100 increases the data transfer rate to 100MB/s.
UltraDMA/100 is backward compatible with DMA/66, DMA/33, and DMA and
with existing DMA devices and systems so there is no need to upgrade current
EIDE/IDE drives and host systems. (UltraDMA100/66 require a 40-pin 80-con-
ductor cable to be enabled.)
•
DDR SDRAM Optimized Performance: This motherboard supports a new gen-
eration memory, Double Data Rate (DDR) Dynamic Random Access Memory
(SDRAM), which is compatible to the industry standard SDRAM. This new memory
technology increases performance by executing two actions per clock cycle,
resulting in data transfer rates of up to 2.1 GB/s for 133MHz DDR SDRAM and
1.6GB/s for 100MHz DDR SDRAM.
ASUS A7A266 User’s Manual

2. FEATURES
2.1.5 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 (requires ACPI OS support): Turbo LEDs now act as informa-
tion providers. Through the way a particular LED illuminates, the user can de-
termine if there are messages waiting in the mailbox. Asimple 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 98/
Millenium and Windows NT/2000, require much more memory and hard drive
space to present enormous user interfaces and run large applications. The sys-
tem resource monitor will warn the user before the system resources are used up
to prevent possible application crashes. Suggestions will give the user informa-
tion on managing their limited resources more efficiently.
•
•
Temperature Monitoring and Alert: CPU temperature is monitored by the
ASUS ASIC 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.
