NTDEV
1

I’ve modified msahci and called my driver a new name. how can i replace msahci? i’ve found the imagepath in the registry but changing that results in my new driver and msachi being loaded. i don’t want msahci loaded at all.

how can i do this?

thanks

Run Update in Device manager, or map to the new driver SYS file using .kdfiles and a mapping file.

thanks gary. i will do that at some point but for now i just did it the simple way by re-naming msahci to _oldmsahci and using mine as the “real” msahci.

Hi,
You can delete msahci driver and install your driver with your inf file.

use devcon to update your driver
devcon.exe update your_ahci.inf PCI\CC_010601

in the WDK msahci does not have an inf file. is there some other example inf file for a miniport driver?

Look in %windir%\inf for the INF for msachi.
