AUTO DETECT PCI CLK:

SPREAD SPECTRUM:
When the system clock generator pulses, the extreme values of the pulse generate excess EMI. En-
abling pulse spectrum spread modulation changes the extreme values from spikes to flat curves, thus
reducing EMI. This benefit may in some cases be outweighed by problems with timing- critical devices
such as a clock-sensitive SCSI device.
