If you want to install more IDE devices, you can purchase a second
IDE cable and connect one or two devices to the Secondary IDE
channel connector IDE2 on the mainboard. If you have two
devices on the cable, one must be Master and one must be Slave.

can connect the drive audio cable to the onboard sound system.

ROM drive have different kinds of audio cable connectors.
Connect the cable to the appropriate connector.

from the port to the header and then secure the port to an
appropriate place in your system chassis.
