You have selected the IDE mode to enable ahci after installing the operating system.

Nowadays, hard disks are basically serial ports (SATA). Compared with parallel hard drives (IDES), serial hard disks have many advantages. However, the hard drive of most computers is still working in IDE mode. This is because the operating systems before xp sp3 do not contain SATA drivers. Therefore, to install XP of SP2, You must select the IDE mode for the serial hard drive; otherwise, a blue screen is displayed when you enter the system, in addition, the XP core PE cannot recognize SATA hard disks. Therefore, the Computer City installer usually changes the hard disk mode to ide before the installation, so that the compatibility is relatively good, while avoiding some ignorant users to feel overwhelmed when installing the XP blue screen. However, the SATA hard drive cannot take advantage of the SATA hard drive in IDE mode. Therefore, we recommend that you enable the SATA mode for the serial hard drive.

 

 

XP operation method

1. confirm that the motherboard driver has been installed (you can reinstall the driver if you are not sure );
2. After installing the driver, click setup.exe in the folder. Note: An error Prompt window will pop up when the driver is installed to the end. At this time, do not click the error Prompt window (just let it stop in the error prompt status! Remember !)
3. Select my computer, right-click and select "properties", select "hardware", and click "Device Manager ";
4. Click the plus sign on the left of the IDE/atapi controller. Two "******** controller" devices are displayed;
5. Right-click a device and choose "select" from the shortcut menu. Select the "driver" tab and select the "Update driver" option;
6. You are welcome to use the hardware Update Wizard. Ask if you want to connect to the Internet or new. Select "No for now" and click "Next "; select "Install from list or specified location" and click "Next ";
7. Select "do not search, I want to select the driver to be installed" and click "Next" and select "disk installation". The "find file" window appears, select the path to "C:/Windows/temp/iif2/winall/driver" and double-click the "iaahci" file in the window. A series of device models will appear in the window, now most models are "ICH9M-E/m", after selection, the system will display driver installation update interface;
8. After the update is complete, Do not restart the machine. Continue to update another "*** controller" device in the Device Manager;
9. After the drivers are updated on both devices, restart the machine and press f2 to enter the BIOS to change the hard disk mode to "ahci ";
10. After the machine starts normally, the system will prompt you to find the new hardware and enable it automatically. Don't worry. It's not over yet! Re-import the driver to the shenzhou.com drive, and then run setup.exe on the ahcid drive. All right! This time the program will be installed normally and no error will be reported. Restart the machine after installation. OK! Conquer it like this !!!
11. Follow these steps strictly. Do not continue without one link, or modify the BIOS settings. Otherwise, the blue screen cannot be accessed.
12. The above operations are limited to Intel pm45/gm45 + ich9 chip models. Do you have to consider other models carefully!
13. I copied an old post from a friend in the jar, but modified some details. Thank you again!
14. It is said that after the ahci mode is started, hard disk partitions are preferably in NTFS format, so we recommend that you modify the fat format.
