SATA M ? how to enable?

[_Jimlad_]

Hello i have Z68 Extreme4 Gen3

and have 8 SATA ports, all been working well over the last 18 Months, however i have needed to add more drives and have now found the SATA 'M1 & M2' don't work?

any ideas, nothing stood out in the bios to enable

Any option in bios to enable Marvell chipset, as I think that's what the grey ports are on that motherboard? If enabled are the drivers installed in Windows?

Edit: In bios go to Advanced>Storage Configuration - there should be a couple of options at the top fro the marvell chipset.
