11. DieHard BIOS II (For AX4C-G, AX4C Max)
(AX4C Pro, User Upgrade Optional)
Many viruses have been found that they may destroy bios code and data area lately. This
motherboard implements a very effective hardware protection method without any software or
BIOS coding involved, therefore it is 100% virus free. You may restore the originally mounted
BIOS with 2
nd
BIOS ROM by setting JP24 to pin 2-3 if it fails to work properly.
12. Memory Module (128-Bit DDR Dual Channel)
10. S/PDIF (Sony/Philips Digital Interface) Connector
(AX4C Pro, AX4C Max only)
S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides
impressive audio quality through optical fiber and allows you to enjoy digital audio instead of
analog audio. 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 better audio quality. Through a specific audio cable, you can connect the S/PDIF
connector to other end of the S/PDIF audio module, which bears S/PDIF digital output.
However, you must have a S/PDIF supported speaker/amplifier/decoder with S/PDIF digital
input to connect to the S/PDIF digital output to make the most out of this function.

In the past, we used to have 64-bit memory bandwidth for memory access. No matter how
many memory modules have been installed, though capacity added, the speed of access
remains the same. With 128-bit dual channel introduced, it doubles the memory bandwidth
up to 5.4GB in advanced 128-bit mode. This motherboard supports DDR400/333 with
Maximum capacity up to 4GB.

With AGERE 1394 Control chip (with AGERE FW323), the IEEE 1394 provides data
transfer rate up to 400Mb/s, and USB just has 12Mbps. Hence, 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.
