Reverting to MS AHCI driver?

[stranexuk]

Hi all,

I am trying to troubleshoot a problem I'm seeing whilst trying to access a removeable CF-SATA card reader using Intel PCH SATA AHCI drivers.

My OS was setup with the BIOS set to AHCI and the regisrty confirms me having AHCI drivers enabled.

How to I revert to the MS drivers from the current Intel ones? If I look in "Driver Details" under Device manager, the "Roll back driver" is greyed out. Is it simply a matter of Uninstalling the driver and allowing Win to build the default one at next boot or would that be asking for all sorts of trouble!?

Any help gratefully received...

I am not very knowledge in this area, so any advice will be at your own risk. I say this because if your OS is installed under AHCI, it will not boot without it. However go into device manager and find your ahci driver. it will probably be located under IDE ATA/Atapi controllers. right click it and go to the drivers tab. Click on update drivers button. It will ask whether to look on the internet or on your computer. Choose look on your computer. Then choose 'let me pick the driver'. I think you will find your drivers in C:/windows/system32/drivers. Choose the driver named msahci. this should change the controller back to the windows controller for ahci. You will probably have to reboot (that is where the fun begins) When windows begins to load up, you should see a baloon saying windows is loading drivers. If you see that it will probably work. If at any time before you choose the msachi driver you change your mind you will have the opportunity to push cancel and will have therefore done nothing. That is what I would try. what you choose is up to you.

Thanks, that was what I was thinking but wasn't sure where to find the MS drivers.....now I do!

Anyone else like to give their opinion before I light the blue touch paper?!?
