I have installed a new SSD in my Aspire M3641 and it runs fine with Windows 8.1 but I am sofar unable to set it up with AHCI. Under Windows 8.1 I use these instructions:

Unfortunately I cannot find the relevant AHCI settings in my bios (latest M3641 bios version from acer.com)

 

Can anybody point me in the right direction?
