7. Each integrated drive electronics (IDE) drive requires two cables; a four-wire
power cable that connects to the power supply and a signal cable that connects to
the system board. For a CD-ROM drive, you might also have an audio cable.
The steps to connect an IDE drive are different depending on the type of drive you are
connecting. Locate the procedure below for your drive connection.
To connect the first IDE CD drive or DVD drive
1. Locate the three-connector signal cable that came with your computer or with the
new drive.
2. Locate the secondary IDE connector on the system board. See "Identifying parts
on the system board" on page 51.
3. Connect one end of the signal cable to the drive and the other to the secondary
IDE connector on the system board. To reduce electronic noise, use the connectors
at the end of the cable only.
4. Your computer has extra power connectors for additional drives. Connect a
power connector to the drive.
