2.10.1 Auto Detect PCI Clk

This allows you to enable or disable auto detect PCI clock. The choices are "Enabled" and

"Disabled".

2.10.2 Spread Spectrum

This setting allows you to reduce EMI by modulating the signals the CPU generates so that

the spikes are reduced to flatter curves. This is achieved by varying the frequency slightly

so that the signal does not use any particular frequency for more than a moment. The

choices are "Disabled" and "Enabled".
