« Note:

1.If you use 100/133 MHz CPU, We recommend you to setup your system speed to “Auto” value.

2.We don’t recommend you to set up your system speed to 122, 142, 150,159 MHz

because these frequencies are not the standard specifications for CPU, Chipset and most of the peripherals. Whether your system can run under 122 , 142 , 150 ,159 MHz properly will depend on your hardware configurations: CPU, SDRAM, Cards, etc.

**If you want to set up your system speed to 122, 142, 150,159 MHz, you must change the Jumper JP9 from 2-3 close to 1-2 close.

Line Out 1: Line Out or SPDIF (The SPDIF output is capable of providing digital audio to external speakers or compressed AC3 data to an external Dolby digital decoder). In general, Line Out 1 is normally Line Out, when it output digital signal, it will be change to SPDIF Out automatically (see page 47 for more information). Line In: In general, Line In is normally Line In. When you select “Four Speaker” in Creative application (see page 45 for more information), Line In will be

change to Line Out 2, then you can plug 2 pairs stereo speaker into Line Out 1 and Line In simultaneously.
