4.SMB2.0 (two 2-pin SMB20)

These jumpers allow you to enable or disable the SMBus 2.0 feature supported on the motherboard. By default, these jumpers are shorted (jumper caps on) to disable the feature. If you wish to install PCI devices that comply with SMBus 2.0 specification, remove the jumper caps to enable the SMBus 2.0 feature.

This connector supports the provided floppy drive ribbon cable. After connecting one end to the motherboard, connect the other end to the floppy drive. (Pin 5 is removed to prevent incorrect insertion when using ribbon cables with pin 5 plug).
