Bus Clock - SOYO SY-6ZB User Manual

Hardware Setup
Step 16. Set SW1 for power up FSB clock and AGP

bus clock.

SW1 is used to adjust AGP bus clock frequency depending on the value
of the front side bus (FSB) clock, also the setting of the SW1
determines the power up FSB clock which will remain effective until the
BIOS set the FSB clock to the CMOS setting.
SW1 Setting
Note: The specification of maximum AGP bus Clock frequency is 66.6MHz.
∗
Set SW1 to open when you use a FSB 100MHz CPU.
∗
Set SW1 to close when you use a FSB 66MHz CPU.
∗
Set SW1 to open when you use a FSB 66MHz CPU but want to over
clock the FSB clock to 100MHz via the BIOS setting.
Step 17. Power On
You have now completed the hardware installation of your
Motherboard successfully.
1. Turn the power on
2. To enter the BIOS Setup Utility, press the <DEL> key while the
system is performing the diagnostic checks,
Note: If you have failed to enter the BIOS, wait until the boot
up sequence is completed. Then push the RESET button and
press <DEL> key again at the beginning of boot-up, during
diagnostic checks.
Repeat this operation until you get the following screen.
