• Supports up to 2GB system memory
• Synchronous operation with processor system bus
- PC2700/PC3200 (DDR333/DDR400) with 800MHz FSB
CPU. DDR333 will run at 320MHz memory frequency when
used with 800MHz FSB CPU.
- Use PC2100/PC2700 (DDR266/DDR333) with 533MHz
FSB CPU

Expansion Slots
• 1 AGP slot
• 3 PCI slots
AGP (Accelerated Graphics Port)
• Supports AGP 3.0 (AGP 4x and 8x) and AGP 2.0 (AGP 1x and
4x) spec.
• Supports 1.5V AGP 8x (2.13GB/sec.) and AGP 4x (1066MB/
sec.) add-in cards.
AGP is an interface designed to support high performance 3D
graphics cards for 3D graphics applications. It handles large
amounts of graphics data with the following features:
• Pipelined memory read and write operations that hide
memory access latency.
• Demultiplexing of address and data on the bus for nearly
100 percent efficiency.
Note:
AGP 2x and 3.3V AGP cards are not supported.
Onboard Graphics Features
• Graphics memory
- Shares 1MB/8MB/16MB of the system memory in DOS
mode
- Uses Dynamic Video Memory Technology (DVMT) in
Windows mode
• Graphics controller
- Core frequency of 266MHz
- 350MHz integrated 24-bit RAMDAC

2.5.2 Serial Ports
"
"
The serial ports are RS-232C asynchronous communication ports
with 16C550A-compatible UARTs that can be used with modems,
serial printers, remote display terminals, and other serial devices.
The system board is equipped with an onboard serial port (CN4 -
Teal/Turquoise) for COM 1 and a 9-pin connector at location J6 for
COM 2.
One card-edge bracket, mounted with a serial port cable, will be
provided as an option. If you want to use the COM 2 serial port,
connect the serial port cable to connector J6. Make sure the colored
stripe on the ribbon cable is aligned with pin 1 of connector J6.
Mount the card-edge bracket to the system chassis.
BIOS Setting
Select the serial ports’ I/O address in the Integrated Peripherals
submenu (“Super IO Device” section) of the BIOS. Refer to chapter
3 for more information.

2.6.3 S/PDIF Connector
The system board is equipped with a S/PDIF connector. One card-
edge bracket, mounted with S/PDIF ports, will be provided as an
option. Install the card-edge bracket to the system chassis then
connect the audio cable connector to J3. Make sure pin 1 of the
audio cable connector is aligned with pin 1 of J3.

2.6.13 Front Panel Connectors
HD-LED: Primary/Secondary IDE LED
This LED will light when the hard drive is being accessed.
RESET: Reset Switch
This switch allows you to reboot without having to power off the
system thus prolonging the life of the power supply or system.
SPEAKER: Speaker Connector
This connects to the speaker installed in the system chassis.
ATX-SW:ATX Power Switch
Depending on the setting in the BIOS setup, this switch is a “dual
function power button” that will allow your system to enter the Soft-
Off or Suspend mode. Refer to “Soft-Off By PWR-BTTN” in the
Power Management Setup (Chapter 3).

PWR-LED: Power/Standby LED
When the system’s power is on, this LED will light.When the system
is in the S1 (POS - Power On Suspend) or S3 (STR - Suspend To
RAM) state, it will blink every second.
Note:
If a system did not boot-up and the Power/Standby LED did
not light after it was powered-on, it may indicate that the CPU
or memory module was not installed properly. Please make
sure they are properly inserted into their corresponding socket.
