Does my old mobo need this AHCI thing?

@Paultx check your bios if it has the option to switch between IDE and AHCI if it has AHCI then just enable it , next stop look for the AHCI driver compatible with your board , don't leave it to windows windows update , find it and install it yourself , even if it says for windows 8.1 , you will notice a gain for sure over the IDE , i have few systems that belong to that era and i know for sure AHCI made a difference for which , specially that they were all SATA 2 and any improvement if minor is a plus .

And if you don't prepare Windows for the switch from IDE to AHCI before you change the setting in BIOS the computer will fail to boot.

sorry just saw this and no , during boot windows will detect new interface as new hardware and install proper drivers for it and that's about it , he can even keep switching back and forth now and the driver sets of both would just go offline and hide no need to uninstall which .

Then I guess this tutorial is just a waste:
Enable AHCI in Windows 8 and Windows 10 after Installation

My experience has been that IDE drivers need to be removed or disabled before the computer will load Windows after switching modes in BIOS.

I just read the tutorial , i don't know if its a windows build or what but my case starts from step 18 smoothly , someone should test and report .

P.S Brink never deletes old IDE drivers he just switch state of few flags in registry that enables using windows in AHCI mode so i gather if these on certain builds are enabled by default then the scenario should go smooth .

Also i'll try to check later the status of these flags on the systems i did the switch on and see if this is how they are set or differently .
