Xp system to open AHCI mode computer blue screen solution

Question: The situation is like this. I have a computer with a SATA hard disk. I can detect the correct information of the hard disk in the BIOS of the motherboard. After the AHCI mode is enabled, I enter the Windows XP operating system and the blue screen prompts “0X0000007B”. What is the problem caused by this? Please advise the expert.

Answer: It is best to explain to you what is AHCI, AHCI is the "Serial ATA Advanced Host Controller Interface" Serial ATA advanced host interface. Choosing AHCI will open the ncq function of the hard disk. Relatively speaking, the technology is more advanced, but some people say that it is not mature, but in my case, the ahci mode is better than other modes. The disadvantage is that the ahci driver is required when installing the system. XP does not support AHCI. So it is better to change SATA. Only VISTA and WIN7 can better support the possibility 1. Because XP does not bring AHCI driver, if you want to enable AHCI, you should manually load AHCI driver when installing XP, or use integrated AHCI driver. XP installation disk, or directly install VISTA or WIN7. Possibility 2, mode setting error: Maybe your hard disk does not support AHCI mode, which causes the hard disk to be recognized at boot time and the blue screen is changed to IDE or ATA mode.
