•
USB Port Connector: This motherboard supports two USB port connectors for USB devices.
•
Optional IrDA: This motherboard supports an optional infrared port module for wireless
interface, with independent 3rd UART (32-byte FIFO).
•
AGP: Accelerated Graphics Port, for to 533MB/sec data transfer rate and 66MHz Bus clock to
improve graphic functions.
•
ATX Form Factor: Dimensions 30.5cm x 19cm.
* Your memory module(s) must be PC133 compliant SDRAM chips and specified or marked
as 8ns or 6ns.
* When you are running at 133MHz , make sure all of your PCI devices have enough
tolerance to run on 44MHz . Otherwise, it may cause your system become very unstable.
