Thanks for joining the Desktop Board community.
I understand your computer is having some issues with AHCI and data recovery with FreeBSD.
Please bear in mind the latest Intel® Rapid Storage drivers provide support for AHCI, you may want to try version 13.1
Also, Intel does not provide support for Linux operating systems. If you are facing problems with FreeBSD, I recommend contacting Linux community to see if there are any drivers available that will provide you with the functions you require.
