3.8 External Connectors
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 connectors 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.
1) PS/2 Mouse Connector (6-pin PS2KBMS)
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 BIOS Features Setup.
PS/2 Mouse (6-pin Female)
2) PS/2 Keyboard Connector (6-pin PS2KBMS)
This connection is for a standard keyboard using an PS/2 plug (mini DIN). This
connector will not allow standard AT size (large DIN) keyboard plugs. You
may use a DIN to mini DIN adapter on standard AT keyboards.
