3.8 External Connectors

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 to

Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connec-

tor on hard drives and CD-ROM drives, but may be on the opposite side on

floppy disk drives. Check the connectors before installation because there may

be exceptions. IDE ribbon cables must be less than 46 cm (18 in.), with the

second drive connector no more than 15 cm (6 in.) from the first connector.
