Dell D820 laptop BIOS with disk controller option
Posted: Fri Oct 28, 2016 6:48 am
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?
