connectors are labeled on the motherboard. Pin 1 is the side closest to
the power connector on hard drives and 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.

2. PS/2 Mouse Connector (6-pin block)
If you are using a PS/2 mouse, you must purchase an optional PS/2
mouse set which connects to the 6 pin block and mounts to an open
slot on your computer's case. The system will direct IRQ12 to the
PS/2 mouse if one is detected. If not detected, expansion cards can use
IRQ12. See PS/2 Mouse Control in BIOS FEATURES SETUP.
