EFAULT

The on-board audio controller is disabled.

Spread Spectrum [Disabled]

Use the Spread Spectrum option to reduce the EMI. Excess EMI is generated when the

system clock generator pulses have extreme values. Spreading the pulse spectrum

modulates changes in the extreme values from spikes to flat curves, thus reducing the

EMI. This benefit may in some cases be outweighed by problems with timing-critical

devices, such as a clock-sensitive SCSI device.

Disabled D

EFAULT

EMI not reduced
