SSD I want to enable AHCI mode but I can't find SATA Mode in BIOS

[andrE1122]

Hello,
I want to enable AHCI mode but I can't find the option SATA Mode in BIOS. On other ASUS MBs it should look like this: http://i.imgur.com/E6wgizB.png . The options marked with a red circle are the ones my BIOS are missing. My motherboard is ASUS B150M-A/M.2 and I updated my bios from 0403 to 2003 ( still nothing ). Could it be that my motherboard does not support AHCI mode? If it does is there a way I can fix this ?

Thank you,
Andrej.

Try in BIOS Legacy mode.

Try in BIOS Legacy mode.

I've tried setting everything on Legacy Mode but it still gives me the UEFI BIOS when I enter it.

looks same problem.
Only mode is AHCI.
