6. Support the 3rd USB2.0 Channel
This motherboard provides four USB connectors to link USB devices, such as mouse, keyboard, modem, printer, etc. There are two connectors on the PC99 back panel. You can use proper cable to connect other USB connectors to the back panel or front panel of chassis.

8. S/PDIF Connector

S/PDIF (Sony/Philips Digital Interface) is a latest audio transfer file format that provides impressive quality through optical fiber and allows you to enjoy digital audio instead of analog. Normally there are two S/PDIF outputs as shown, one for RCA connector, the most common one used for consumer audio products, and the other for optical connector with a even better audio quality. Through a specific audio cable, you can connect the S/PDIF connector to a S/PDIF audio module bearing S/PDIF digital output. However, you must have a S/PDIF supported speaker with S/PDIF digital input to make the most of this function.

10. IEEE 1394 Connectors (MX46-533 Max Only)
This motherboard has three IEEE 1394 connectors onboard. The IEEE 1394 provides data transfer rate up to 400Mb/s, and USB just has 12Mb/s. Therefore the IEEE 1394 interface can connect with the devices that need high data transferring performance, such as digital camera, scanner or others IEEE 1394 devices. Please use the proper cable to connect with devices. Pin 1
12. Chassis Intrusion Connector
The CASE OPEN header provides chassis intrusion-monitoring function. To make this function works, you have to enable it in the system BIOS, connect this header to a sensor somewhere on the chassis. So, whenever the sensor is triggered by lights or by the opening of the chassis, the system will beep to inform you. Please be informed that this useful function only applies to advanced chassis, you may purchase an extra sensor, attach it on your chassis, and make a good use of this function.

17. BIOS Upgrade Under Windows Environment
You may accomplish BIOS upgrade procedure with EZWinFlash by the following steps, and its STRONGLY RECOMMMANDED to close all the applications before you start the upgrading.
Download the new version of BIOS package zip file from our official web site. Unzip the download BIOS package (ex: WMX46533V102.ZIP) with WinZip (http://www.winzip.com) in Windows environment. Save the unzipped files into a folder, for example, WMX46533V102.EXE & WMX46533V102.BIN. Double click on WMX46533V102.EXE, EZWinFlash will detect the model name and BIOS version of your motherboard. If you had got the wrong BIOS, you will not be allowed to proceed with the flash steps. You may select preferred language in the main menu, then click [Start Flash] to start the BIOS upgrade procedure. EZWinFlash will complete all the process automatically, and a dialogue box will pop up to ask you to restart Windows. You may click [YES] to reboot Windows. Press <Del> at POST to enter BIOS setup, choose "Load Setup Defaults", then Save & Exit Setup. Done!
