How XP installs AHCI driver

Said in front: AHCI drive installation can improve your hard drive read and write speed of 30% or so, if your installation is not successful may result in blue screen, the risk is large, recommend you install AHCI high-speed drive before doing a ghost backup, if there is a key to restore, It is recommended that you use DOS mode before attempting to install AHCI driver in XP.

First, we need to understand the XP installation of AHCI driver steps, we first said that there is an XP system in the case of the installation:

1, prepare the Machine official website the correct model of AHCI drive (this is very important, do not believe at random from the online driver);

2, save your XP image or a key restore file (for installation failure to restore);

3, into XP after the installation of AHCI driver (detailed procedures here in detail later);

4, after installation, restart the system, into the BIOS, set SATA mode/ide for AHCI (if the normal installation of AHCI driver, this is not selected AHCI mode start will be blue screen);

5, with AHCI mode into the system, and then use the official Windows mode of installation program (EXE file) again updated, restart, finished.

Below we say 3 details of the installation under XP (Special note: If the installation process fails, the system will not start, you need to prepare to use the previous backup to restore at any time):

A, enter the system, find "Device Manager"-"IDE Controller", right key in the two controller, update the driver;

B, select "list or specify location to install";

C, in the hint of "Compatibility hardware", select the dual-channel IDE;

D, replace the two controllers that are in use with dual channels (replace only one, reboot will be blue screen), right click on one of the dual-channel controller (just one, if two do, blue screen), update the driver, choose to install from disk, find the previously placed on the hard drive AHCI Drive folder, find IAAHCI file (if you display the file name extension, this is an INF file, do not point Iastor file, look at the picture below), formally start installation drive.

(If the IDE controller is not replaced with a dual channel, this step is done directly, blue screen)

E, IAAHCI This driver package may contain multiple drivers, please carefully select their own hard drive corresponding to the drive model (this is either asked on the official web, or try it yourself, the price is if the wrong choice, blue screen), the installation will have a warning, click "Yes".

F, after completion, reboot, into the BIOS to set mode to AHCI, save the BIOS, reboot, AHCII drive installation completed, look at the image below, the original many of the IDE channel only one or two.

Special NOTE: If the XP system does not boot into, explain the AHCII drive installation process selection problem, only into the BIOS, change mode for the IDE, reinstall the system, and then if you do not want to toss, that is, using the IDE mode, if you want to try again, continue the steps above, careful every time the choice, Make an attempt. The easiest place to make mistakes is step c and step e.

Second, if you want to install the system on the installation of AHCI driver, this is more cumbersome, the steps are:

1, need your system disk correction and has joined the AHCI drive, otherwise you need to keep the AHCI drive in advance in the disk (now is generally a U disk, rarely see floppy disk);

2, start Windows XP installer (is the original installation of that, not ghost installation), when you see press F6 if you need to install a third party SCSI or RAID driver information, immediately pressed the F6 key;

3, insert a disk with AHCI drive, according to the prompts to continue, if you identify your drive, will automatically prompt the installation menu;

4, choose x86 or x64 platform (you want to know your XP system is 32-bit or 64-bit), after the installation is completed automatically back to XP installation interface;

5, later, needless to say.

Three, Win7 under the installation of AHCI drive relatively simple

1, into the BIOS mode is set to ATA or IDE;

2, installation Win7;

3, the Device Manager, the right key to drive the controller driver, uninstall, restart the computer;

4, into the BIOS, the mode is set to AHCI mode, save the BIOS, restart;

5, Win7 will automatically add AHCI driver when started;

6, to prepare the official manufacturer of the Ahcii drive under the Win7 run again, the end;
