IrDA Connector

The IrDA connector can be configured to support wireless infrared module, with this module and application software such as Laplink or Windows 95 Direct Cable Connection, the user can transfer files to or from laptops, notebooks, PDA devices and printers. This connector supports HPSIR (115.2Kbps, 2 meters) and ASK-IR(56Kbps).

Install the infrared module onto the IrDA connector and enable the infrared function from BIOS Setup, UART2 Mode, make sure to have the correct orientation when you plug in the IrDA connector.

AGP (Accelerated Graphic Port) 8X Expansiioonn SSlloott

Integrated GeForce4 MX Graphics, which provides the fastest integrated graphics performance and the most comprehensive set of features. This motherboard provides an AGP 8x slot targeted forhigh-performance3D graphic. AGP uses both rising and falling edge of the 66MHz clock, for 4X AGP, the data transfer rate is 66MHz x 4bytes x 4 = 1056MB/s. AGP is now moving to AGP 8x mode, which is 66MHz x 4bytes x 8 =2.1GB/s. You can also adjust AGP voltage in BIOS within a rage from 1.5V to 1.6V.

Note: Please note that when an extra AGP card is installed and the onboard AGP function in BIOS is disabled, the system can support DDR400/333/266; otherwise it only supports up to DDR333.

AGP Protection Technology and AGP LED

With the outstanding R&D ability of AOpen and its specially developed circuit, this model implements a blend new technology to protect your motherboard from being damaged by over-voltagingof AGP card. When AGP Protection Technology is implemented, this motherboard will automatically detect the voltage of AGP card and prevent your chipsets from being burnt out. Please note that if you install a AGP card with 3.3V, which is not supported, the AGP LED on the motherboard will light up to warn you the possible damage of the exceeding voltage. You may contact your AGP card vendor for further support.

Warning: It is strongly recommended not to install a AGP card with 3.3V, which is not supported, the LED3 will light up to warn you the possible damage.
