1.SATA1: SATA motherboard-IDE device (that is, the hard disk of IDE is used on the motherboard of SATA, please connect of SATA to the SATA1 interface, plug the IDE port of converter into the hard disk IDE, before using, please set the jumper of IDE device as MASTER) 2.SATA2: IDE motherboard -SATA device (SATA's hard disk is used on the IDE motherboard, SATA's data cable is connected to SATA2, the converter'S IDE is plugged into the motherboard IDE. 3.IDE interface devices (such as hard disk, optical drive, etc.) into SATA interface or SATA interface devices into the IDE interface, so that you can connect to the SATA interface on the motherboard, improve the utilization of system resources. Can support DVD, DVD-RAM, MO, CD-ROM, CD-RW, hard disk. 4.Support SATA 100/133 hard disk, ATA 100/133 hard disk, compatible with SATA 1.0 standard, ATA 1.0 standard. 1.5Gbps(150 megabytes /s) transmission rate. 5.Note: The compatibility of the optical drive is worse than the compatibility of the hard disk. Instructions for use: 1. SATA hard disk for IDE-supported motherboard 2. Be sure to turn off the power of the host computer before operation; 3. Open the computer case and insert the IDE socket of the adapter card into the IDE socket of the computer motherboard (the motherboard of the IDE interface); 4. Connect one end of the equipped SATA data cable to the SATA2 socket of the adapter card, and one end to the SATA interface of the SATA device, and set the hard disk switch and jumper; 5. Connect the large end of the equipped power cord to the spare power cord of the chassis power supply, and the small end to the power socket pin of the adapter card (white socket, with 4 pins, pay attention to the direction not to be reversed). At the same time plug in the power cord of the SATA device; 6. After the connection is completed, the computer will boot into the BIOS for device detection. The host computer should be able to correctly identify the connected SATA device and start it for normal use.Note: When using the motherboard's IDE interface, first connect the SATA data cable and power cable to the card, and then connect the card to the motherboard's IDE port. Prevent the card from shaking back and forth when inserting, and don't break the interface.Colour: redMaterial: PCBSize: 5x4x0.25cm Package Contents:1 * IDE to SATA two-way adapter card Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
