Connectors

This section describes and illustrates the internal connectors on the motherboard.

1. Floppy disk drive connector (34-1 pin FLOPPY1)

This connector supports the provided floppy drive ribbon cable. After
connecting one end to the motherboard, connect the other end to the floppy
drive. (Pin 5 is removed to prevent incorrect insertion when using ribbon cables
with pin 5 plug).

2. ATX power connectors (20-pin ATXPWR1, 4-pin ATX12V1)

These connectors connect to an ATX 12V power supply. The plugs from the
power supply are designed to fit these connectors in only one orientation. Find
the proper orientation and push down firmly until the connectors completely fit.

In addition to the 20-pin ATXPWR1 connector, connect the 4-pin ATX +12V
power plug to provide sufficient power to the CPU.

Make sure that your ATX 12V power supply can provide at least 15A on the
+12V lead and at least 2A on the +5-volt standby lead (+5VSB). The
minimum recommended wattage is 300W or above for a fully configured
system. The system may become unstable and may experience difficulty
powering up if the power supply is inadequate.

Do not forget to connect the 20-pin ATXPWR1 and 4-pin ATX12V1 power
plugs. Failure to do so may cause severe damage to the CPU or
motherboard!
