WARNING!
Some pins are used for connectors or power sources. These are
clearly distinguished from jumpers in the 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
connector 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 cable must
be less than 46 cm (18 in.), with the second drive connector no more
than 15 cm (6 in.) from the first connector.
