2. ATX power connectors (20-pin ATXPWR; 4-pin ATX12V)  
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.  
Make sure that your ATX 12V power supply can provide 8A on the +12V lead  
and at least 1A on the +5-volt standby lead (+5VSB). The minimum  
recommended wattage is 230W, or 300W for a fully configured system. The  
system may become unstable and may experience difficulty powering up if the  
power supply is inadequate.

3. IDE connectors (40-1 pin PRIMARY_IDE, SECONDARY_IDE)  
This connector supports the provided UltraDMA IDE hard disk ribbon cable.  
Connect the cable’s blue connector to the primary (recommended) or secondary  
IDE connector, then connect the gray connector to the UltraDMA100 device  
(hard disk drive) and the black connector to the UltraDMA100 master device. It is  
recommended that you connect non-UltraDMA100 devices to the secondary IDE  
connector. If you install two hard disks, you must configure the second drive as a  
slave device by setting its jumper accordingly. Refer to the hard disk  
documentation for the jumper settings. BIOS supports specific device bootup. If  
you have more than two UltraDMA100 devices, purchase another UltraDMA  
cable. You may configure two hard disks to be both master devices with two  
ribbon cables – one for the primary IDE connector and another for the secondary  
IDE connector.  
1. Pin 20 on each IDE connector is removed to match the covered hole on the  
UltraDMA cable connector. This prevents incorrect orientation when you  
connect the cables.  
2. The hole near the blue connector on the UltraDMA cable is intentional.  
NOTE: Orient the red markings  
(usually zigzag) on the IDE  
ribbon cable to PIN 1.
