2. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
This connector is for an Ultra DMA 133 signal cable. The Ultra
DMA 133 signal cable has three connectors: a blue connector for the
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.

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.
Pin 5 on the connector is removed to prevent incorrect cable connection when
using a FDD cable with a covered Pin 5.
• 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 DMA 133/100/66 IDE devices.
