WARNING! Some pins are used for connectors or power sources. These are
clearly distinguished from jumpers in 3.1 Motherboard Layout. Placing jumper
caps over these connector pins 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 for hard drives and
floppy drives. IDE ribbon cables must be less than 46 cm (18 in.), with the sec-
ond drive connector no more than 15 cm (6 in.) from the first connector.
