IDE Connector
The IDE connector connects to an IDE 80-pin interface ribbon
cable.
NOTE: The cable has to meet the specification of
UDMA-66 and above.
Master / Slave / Cable Select Jumper (JP1)
This jumper allows the
user to set the 7500 up as
either an IDE Master,
Slave, or Cable Select
device.
If the plastic jumper cap is placed on pins 2-3, the 7500 is set
as a Master device. If the jumper cap is completely removed
from the pins, the 7500 is set as a Slave device. If the jumper
cap is placed on pines 1-2, the 7500 is set as a Cable Detect
device, which means the system will automatically try to
identify the drive status.

Cable Select Short pins 1-2
If there are two devices on a single IDE channel, one device
must be designated as Master and one device must be
