3.8 External Connectors

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 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.

The system will direct IRQ12 to the PS/2 mouse if one is detected. If not de- tected, expansion cards can use IRQ12. See PS/2 Mouse Function Control in 4.4 Advanced Menu.
