Before I start, it's actually "AHCI". It means "Advanced Host Controller Interface". (I've been seeing this very frequently this past week for some reason)
Anyway, here is an excerpt from a guide
on OCZ's message board:Change from IDE to AHCI Mode after InstallationInformation:
AHCI stand for Advance Host Controller Interface. AHCI is a hardware mechanism that allows software to communicate with Serial ATA (SATA) devices (such as host bus adapters) that are designed to offer features not offered by Parallel ATA (PATA) controllers, such as:
- Native Command Queuing (NCQ) -might improve computer/system/hard disk responsiveness, especially in multi-tasking environment
You can read more about AHCI mode HEREInstruction
: There is one way to fix this, although you need to have knowledge of registry editing.
The detailed steps from Microsoft website are as follows:
- In the Value data box, type 0 [3 is default], and then click OK.
- On the File menu, click Exit to close Registry Editor.
- Restart your computer
- Go to BIOS and enable AHCI, Save & Reboot
- Another restart will be required to finish the driver installation.
Just download this Reg File
and double-click to implement AHCI on your Windows-based computer.
Just remember to do the BIOS switch as well when you reboot.
