Installing a Hard Disk Drive/CD-ROM/SATA Hard Drive
This section describes how to install IDE devices such as a hard disk drive and a CD-
ROM drive.
About IDE Devices
Your motherboard has one IDE channel interface.
IDE: IDE Connector
This motherboard supports four high data transfer SATA ports with each runs up to
3.0 Gb/s. To get better system performance, we recommend users connect the CD-
ROM to the IDE channel, and set up the hard drives on the SATA ports.
IDE devices enclose jumpers or switches used to set the IDE device as MASTER or
SLAVE. Refer to the IDE device user's manual. Installing two IDE devices on one
cable, ensure that one device is set to MASTER and the other device is set to SLAVE.
The documentation of your IDE device explains how to do this.
