Note: the XP system does not support AHCI mode, which will cause the computer to boot blue screen and only support IDE mode. SSDs turn on AHCI mode, which will increase the speed of SSDs, and IDE mode will obviously hold you back.

1, take the Win10 system as an example, press the "win key + R key" combination key on the keyboard at the same time to call up and run, enter the "regedit" command to open the registry editor, as shown in the following figure.

2. Open the "HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ services\ msahci" destination path (after the Win8 system, msahci is renamed to storahci), and find the item "Start", as shown in the following figure.

3. We double-click to open the "Start" item and change the default "3" of the numerical data to "0", as shown in the following figure.

4. We navigate to the following four path directories and delete them:

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ iaStorAV\ StartOverride

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ iaStorSV\ StartOverride

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ iaStorV\ StartOverride

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ msahci (or storahci)\ StartOverride

5. If you don't have a directory, ignore it and restart the computer when you're done. After booting, we repeatedly press the Dell key to enter the motherboard BIOS setting interface, as the BIOS settings of different brands of motherboards are different, we just need to find options similar to SATA mode, change IDE mode to AHCI mode, and press F10 key to save and determine.

6. We restart the computer, and after entering the system, we will automatically detect and install AHCI related drivers. We can go to Baidu to download "AS SSD Benchmark" software, that is, we can check whether our hard drive is running in AHCI mode, and the software prompt OK represents success.
