Installing a Hard Dish 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 two IDE channels interface. An IDE ribbon cable supporting two IDE devices is bundled with the motherboard. You must orient the cable connector so that the pin1 (color) edge of the cable correspoinds to the pin 1 of the I/O port connector. IDE1: IDE Connector This motherboard supports two high data transfer SATA ports with each runs up to 150 MB/s. To get better system performance, we recommend users connect the CD-ROM to the IDE channel, and set up the hard dives on the SATA ports.
IDE2: Secondary IDE Connector The second drive on this controller must be set to slave mode. The cinfiguration is the same as IDE1.
IDE devices enclose jumpers or switches used to set the IDE device as MASTER or SLAVE. Refer to the IDE device users 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.

About SATA Connectors

Your motherboard features two SATA connectors supporting a total of two drives. SATA , or Serial ATA (Advanced Technology Attachment) is the standard interface for the IDE hard drives which are currently used in most PCs. These connectors are well designed and will only fit in one orientation. Locate the SATA connectors on the motherboard and follow the illustration below to install the SATA hard drives.
Installing Serial ATA Hard Drives
To install the Serial ATA (SATA) hard drives, use the SATA cable that supports the Serial ATA protocol. This SATA cable comes with an SATA power cable. You can connect either end of the SATA cable to the SATA hard drive or the connector on the motherboard (not contained in the scope of supply).

SATA cable

(optional)

SATA power cable

Refer to 3
the illustration below for proper installation: Attach either cable end to the connector on the motherboard. Attach the other cable end to the SATA hard drive. Attach the SATA power cable to the SATA hard drive and connect the other end to the power supply.

This motherboard does not support the Hot-Plug function.
Installing a Floppy Diskette Drive
The motherboard has a floppy diskette drive (FDD) interface and ships with a diskette drive ribbon cable that supports one or two floppy diskette drives. You can install a 5.25-inch drive and a 3.5-inch drive with various capacities. The floppy diskette drive cable has one type of connector for a 5.25-inch drive and another type of connector for a 3.5-inch drive. You must orient the cable connector so that the pin 1 (color) edge of the cable corresponds to the pin 1 of the I/O port connector.
FDD: Floppy Disk Connector
This connector supports the provided floppy drive ribbon cable. After connecting the single end to the onboard floppy connector, connect the remaining plugs on the other end to the floppy drives correspondingly.

Installing Add-on Cards

The slots on this motherboard are designed to hold expansion cards and connect them to the system bus. Expansion slots are a means of adding or enhancing the motherboards features and capabilities. With these efficient facilities, you can increase the motherboards capabilities by adding hardware that performs tasks that are not part of the basic system.

AGP Slot PCI 1~3 Slots

The AGP slot is used to install a graphics adapter that supports the 8X/4X AGP specification. It is AGP 3.0 compliant. This motherboard is equipped with three standard PCI slots. PCI stands for Peripheral Component Interconnect and is a bus standard for expansion cards, which for the most part, is a supplement of the older ISA bus standard. The PCI slots on this board are PCI v2.2 compliant. Before installing an add-on card, check the documentation for the card carefully. If the card is not Plug and Play, you may have to manually configure the card before installation.
Follow these instructions to install an add-on card: 3 Remove a blanking plate from the system case corresponding to the slot you are going to use. Install the edge connector of the add-on card into the expansion slot. Ensure that the edge connector is correctly seated in the slot. Secure the metal bracket of the card to the system case with a screw.
For some add-on cards, for example graphics adapters and network adapters, you have to install drivers and software before you can begin using the add-on card.
