2. IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)
These connectors are for Ultra DMA 133/100/66/33 signal cables.
The Ultra DMA 133/100/66/33 signal cable has three connectors: a
blue connector for the primary IDE connector on the motherboard, a
black connector for an Ultra DMA 133/100/66/33 IDE slave device
(optical drive/hard disk drive), and a gray connector for an Ultra DMA
133/100/66/33 IDE master device (hard disk drive). If you install two
hard disk drives to the same cable, 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.

1. Floppy disk drive connector (34-1 pin FLOPPY1)
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 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 Ultra DMA133/100/66/33 IDE
devices.
NOTE: Orient the red markings on
the floppy ribbon cable to PIN 1.
