I did the BIOS update and then the "enable AHCI" option appeared and I checked it.
I am uncertain what it means when you state that "Win7 will
NOT boot after you change the setting to AHCI". Is that a good thing or bad thing?
I am certain that my computer is really fast now.
It seems I am maxed out on what the machine will do with the only issue being that my system doesn't support a SATA 6 Gb/s(SATA3) port.
I basically followed this last night after you had me update the BIOS and everything came out fine. I kind of even feel like a computer nerd.
Luckily, after much research, I found a procedure that allowed me to install the SATA AHCI drivers without reinstalling Windows 7.
Thanks to Windows7Themes.net for having the answer:
- Basically, change the following registry key to 0:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\msahci\Start
- Restart the computer once (without changing any BIOS settings) and Windows will load default AHCI drivers. You may not notice anything happening, so let Windows sit for a minute or two after reboot to give it enough time to make sure this process happened.
- Restart the computer again and change the SATA operation to AHCI in BIOS. Save the BIOS settings and when Windows boots again, it should not crash with a blue screen. This time you should notice that Windows is installing new hardware, which includes several SATA AHCI components (similar to what the picture above shows). Windows will probably ask to restart once more.
At this point you should have a functioning Windows 7 install with default SATA AHCI drivers operating. I then was able to install the vendor specific drivers from Intel because they now recognized the controller properly. Yay! A few hours of my life gone, but at least I learned something!
This whole problem could have been avoided if Windows 7 would have installed the AHCI drivers properly in the first place, and/or if the Intel drivers were smart enough to recognize that the controller in ATA mode is in fact the correct controller and simply installed the drivers anyway. But issues like this are why we do what we do, so hopefully my experience will save some of you some grief!
