2. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
These connectors are for Ultra DMA 133/100/66 signal cables.
The Ultra DMA 133/100/66 signal cable has three connectors: a
blue connector for the primary IDE connector on the motherboard,
a black connector for an Ultra DMA 133/100/66 IDE slave device
(optical drive/hard disk drive), and a gray connector for an Ultra
DMA 133/100/66 IDE master device (hard disk drive). If you install
two hard disk drives, 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.
2.7.2 Internal conne ctors
1. Floppy disk drive connector (34-1 pin FLOPPY)
This connector is for the provided floppy disk drive (FDD) signal cable.
Insert one end of the cable to this connector, then connect the other
end to the signal connector at the back of the floppy disk drive.
The Pin 5 on the connector is removed to prevent incorrect cable
connection when using an FDD cable with a covered Pin 5.
• The Pin 20 on the IDE connector is removed to match the covered hole
on the Ultra DMA cable connector. This prevents incorrect insertion
when you connect the IDE cable.
• Use the 80-conductor IDE cable for UltraDMA133/100/66 IDE devices.
