SATA devices 5 & 6 not recognised

I'm upgrading from Centos 7 to 8 but have discovered that SATA disks connected to ports 5 & 6 are not recognised. There was a disk on port 5 and that was recognised by Centos 7. They are identified by the BIOS.

The motherboard is Gigabyte GA-970A-UD3 REV1.2 and the results of lspci (all lines mentioning IDE) is:

00:11.0 SATA controller: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 SATA Controller [IDE mode] (rev 40)
00:14.1 IDE interface: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 IDE Controller (rev 40)

It doesn't look like there is a separate controller for the 5th and 6th ports compared to the first four, all of which are recognised.

Is there any chance that I can get the extra two ports working - this is going to be a backup server so more disk space is going to be fundamental?

Try lspci -nn | grep -i sata not IDE.

That just returns one of the two previous lines:

00:11.0 SATA controller [0106]: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 SATA Controller [IDE mode] [1002:4390] (rev 40)

Go into your BIOS and change this one to AHCI mode.

Thanks for sharing your knowledge - that's resolved it.

That should also be faster.
