5.External Connectors

WARNING! Some pins are used for connectors or power sources. These are clearly separated from jumpers in “Layout Contents.” Placing jumper caps over these will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe on Pin 1 side of the connector. The four corners of the connectors are labeled on the motherboard. Pin 1 is the side closest to the power connector on hard drives and some floppy drives. IDE ribbon cables must be less than 18 in. (46 cm), with the second drive connector no more than 6 in. (15 cm) from the first connector.
