How to support M.2 PCIe SSD?

Hi tcler2025
It looks like the only Linux driver is AHCI.

Are you also running Windows on your machine? I read some
reports that Windows would not boot when the BIOS was switched
to AHCI and some reports where Windows did not care either way.

If you are running Windows, read this:

The last post suggests how to switch from RAID to AHCI and still
keep Windows happy.

Here are some details from my dell laptop with sata=raid running tc-16.x x86_64

Yes,there is a win10 on my laptop.

My goal is detecting the win10 disk from Tiny core linux with default BIOS settings(SATA = RAID On).
So I'm not going to change BIOS/UEFI settings. :-\

BTW，After do more research , I found someone met the same problem with me:
