　　4, how to set the hard disk AHCI mode

The location of the hard drive AHCI mode is generally in the Integrated peripherals Integrated device interface, first select Onchip SATA Type, then see the following three options, Native IDE/RAID/AHCI, if you need to turn off AHCI, Select Native IDE, and then select AHCI. Some notebooks may only have AHCI and ATA and the Disable option, and you can choose ATA mode as well. Also shows compatible mode compatibility, meaning that the native effect is the same.

In this particular note, the BIOS will also have a onchip SATA controller this SATA controller option (as shown below), if the system has been installed, if you choose to turn off the mode, may cause some uncertainties, so if the machine is running no problem, Generally only need to set SATA mode of operation, the controller does not need to shut down.

　　7. Save BIOS settings

After the BIOS modification is complete, press the Y key of the keyboard to save and restart the computer to take effect, as shown in the following figure:

Whether the use of CD-ROM system, or a U-disk installation system, the BIOS is necessary to set up, and the above content is the user set up the BIOS is more common in several aspects, I hope that the above set up skills to bring some help.
