To update the BIOS, you will have to do it under DOS environment.
1. Make a bootable system 3.5" diskette.
2. Then copy the flash utility (eg. awfl823b.exe) and the new BIOS file (eg. P4PB4113A.BIN) onto this diskette. The latest BIOS update and flash utility can be downloaded from www.viavpsd.com for your specific product.
3. Boot the computer using this diskette.
4. At the A:> prompt type awfl823b.exe P4PB4113A.BIN.

You can find out additional parameters of the flash program by type "awfl823b/?". This will cause the flash utility to load and automatically use the new file. Just follow the prompts that you see on the screen. When you are through, reboot your computer. Please load the optimized default settings in the BIOS.

WARNING!! During the final flash process, power should not be disconnected and the process should not be interrupted or the motherboard will not be able to boot up.

With IEEE 1394 device, you can transfer data at 400Mb/s based on the IEEE 1394 port. In addition, IEEE 1394 supports TCP/IP protocol over IEEE 1394 function. So far, drivers for Windows XP/ME operating system are supported by Microsoft. If you are using Windows 2K/98 operating system, you will need to check the driver's availability from third party support. Based on the Windows XP/ME, you will find 1394 Net Adapter in device manager to support the function similar to LAN. However, there is a limitation in the cabling, you have to use the IEEE 1394 cable and the length should be within 4.5m.
