Whether it is AHCI mode or ACHI mode. Grandma drops, encyclopedia has both

In layman's terms, IDE is ATA mode, is a parallel port transmission mode, 04 years ago popularized technology, the theoretical maximum is 133MB per second, AHCI is SATA mode, serial port transmission mode, new technology, fast transmission speed, theoretical maximum 300MB per second.

1. Adjust to IDE mode in order to install the system that does not inherit the SATA driver, after installing the system, you must install the SATA driver and then change the working mode back to ahcii, otherwise your hard disk can only play 30% of the performance;

2. In the process of installing the system, whether it is GHOST or the XP system that does not integrate the SATA driver in the installation CD, there will be installation failure or a blue screen after booting after GHOST, all because the hard disk mode of AHCI cannot be supported;

3. The performance of AHCI hard disk mode is not only the speed improvement, the relatively early IDE hard disk mode, AHCI provides more new functions to support, these new functions are the key to improve the read and write performance of the hard disk;

4. To put it simply, ahci is a new hard disk algorithm, which can effectively improve the performance of mechanical hard disks and support some special functions.

5. The AHCI mode is the opposite of the IDE mode, and the SATA driver needs to be installed when installing the system (and it seems that only this mode can turn on the NCQ function). If you do not install the AHCI driver when you install the system initially, it will not be turned on, and it will be blue screen after opening, in this case, you must first select the BIOS back to IDE mode, manually install the AHCI driver, modify the registry, and select AHCI to restart.

Note: 1. If you want to install the original version (Windows XP SP3), it will be blue screen during the installation process, the reason is very simple. The original version (Windows XP SP3) does not integrate SATA driver, how to deal with it:

Then change the AHCI mode to IDE mode in BIOS. After the system installation is completed, install the SATA driver with the CD-ROM that comes with the motherboard, and then go to the BIOS to change the corrective Li IDE mode to the ahci mode;

2. If the system has been installed, it is now blue screen or keeps restarting after turning on AHCI mode.

Solution: Go to the BIOS and change the AHCI mode to IDE mode. Enter the system, use the motherboard's built-in CD-ROM to install the SATA driver, and then go to the BIOS to change the IDE mode to AHCI mode.

In the dialog box that pops up, move the cursor to AHCI, which is the SATA interface mode.
