5. External Connectors

WARNING! Some pins are used for connectors or power sources. These are
clearly separated from jumpers in "Map of the ASUS Motherboard." Placing
jumper caps over these will cause damage to your motherboard.
IMPORTANT: Ribbon cables should always be connected with the red stripe on the
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 cable must be less than 18in. (46cm), with the second drive
connector no more than 6in. (15cm) from the first connector.
