CAUTION
Do not move any jumpers with the power on. Always turn off the power and unplug the power cord from the computer before changing a jumper setting. Otherwise, the Desktop Board D865GLC could be damaged.

The figure below shows the location of the jumper blocks.

	With jumpers installed, the audio line out signals are routed to the back panel audio line out connector.
	With jumpers removed, the connector provides audio line out and mic in signals for front panel audio connectors.

CAUTION
Do not place jumpers on this block in any configuration other than the one described in the table below. Other jumper configurations are not supported and could damage the Desktop Board.

Integrator's Note
When the jumpers are removed and this connector is used for front panel audio, the back panel audio line out and mic in connectors are disabled.

The 3-pin jumper block determines the BIOS Setup program's mode. The table below describes the jumper settings for the three modes: normal, configure, and recovery. When the jumper is set to configure mode and the computer is powered-up, the BIOS compares the processor version and the microcode version in the BIOS and reports if the two match.
