The IDE mode and AHCI mode of the hard disk are installed when the win7 system is installed and the AHCI driver downloads

                                                                                                                                                                                         

The current desktop is also good, notebook
also, the new machine is generally Intel Core I3, I5 series cpu, then in order to let the performance of the new cpu fully play, business recommendations The new machine is best installed with win7 or above, so many new machines are pre-installed with windows
7 system, for those of us who are used to winXP system, do not want to follow the trend What do you like to love? So many old birds have replaced the win7 system with the traditional winXP system, but the problems that come with it have appeared. Let me talk about several common problems.

After we arrived at the new machine, we changed the win7 system to winXP system and found that as long as the screen is blue, what is the reason? Generally caused by this situation is the hard disk setting mode, because the default hard disk mode of the new machine installed win7 is AHCI, but when we installed winxp, the hard disk mode has not changed, or AHCI, but winxp to IDE mode Very friendly, so there will be incompatible blue screen phenomenon, the solution is very simple, when the system starts, we enter the BIOS, change the mode of the hard disk to IDE, save and launch the restart machine to solve the blue screen problem.

For the above question, it is still simple, but some people just like toss, but we used winxp soon, and would like to taste the flavor of Windows7, so we will be hard-working Win7 system, when we have a lot of experience to install win7, IDE mode can enter the system normally, but we have heard that AHCI mode hard disk runs faster, so we continue to adopt early, the default IDE mode is directly changed It became the AHCI mode. At this time, the tragedy appeared again. The boot is still blue screen. Why is this? In fact, this problem is also very simple, your system default is the IDE mode, of course, the IDE driver is matched, you directly change to AHCI mode, the system can not find the AHCI driver, of course, you have to strike the blue screen, know that is The problem with the driver, the solution is simple.

We need to download the AHCI driver (link: http://pan.baidu.com/s/1i3gl37Z). The package contains four drivers, ahci32, ahci64, IRST32, and IRST64. 32 corresponds to a 32-bit system, 64 corresponds to a 64-bit system. If your motherboard is a series after 945, then use ahci. If your motherboard is a motherboard platform after intel 55, 65, 67, then Please choose IRST. If you don't know what motherboard series you are, try IRST first, then try ahci.

About the specific usage, after you get the corresponding driver, after decompressing, there is a folder called prepare inside, find install.cmd inside, then right click "run as administrator" ” , there will be a flash window, after the operation, we restart the computer
, at startup, we enter the BIOS, set the hard disk mode to AHCI, then save and restart, when we enter the system again, win7 system will Prompt to find new hardware, install new hardware drivers, generally the system is automatically completed, will prompt to restart again after completion, we restart, and then enter the system, generally normal.
