2 ) IDE1 (IDE cable connector)
An IDE device connects to the computer via an IDE connector. One IDE connector can connect
to one IDE cable, and the single IDE cable can then connect to two IDE devices (hard drive or
optical drive). If you want to connect two IDE devices, please set the jumper on one IDE device
as Master and the other as Slave (for information, please refer to the instructions located on the IDE
device).
Before attaching the IDE cable, please take note of the foolproof groove in IDE connector.
