We're trying to install Windows 7 on our D820 and we need to set the disk controller in the BIOS menu. The D820 had A09 so we upgraded to A10, but still no option to access a disk controller. Seems we need a downgrade instead of an update. Any suggestions?

I am not seeing any mention of a disk controller needing to be set here:

Not even for windows 10.So, where are the instructions coming from?
