Hello, I have a new gigabyte motherboard 970A-UD3P (rev 1.0) installed. Bios F1 07/06/2013. Serial Number SN133640037609. VGA ATI Radeon Sapphire HD 5450. CPU AMD FX 6300 3.50 Ghertz. Memory 8G kingston DDR3 1600 Ghertz. Power supply 600 watts. I am having problems loading Linux software. * No USB mouse is laoding.Error "usb 9-1" is seen. * No network internet eth0 is loading= no wired connection error given. All settings is set to legacy since this Linux worked before on my old UFI motherbaord with all the same standard settings. This is a Uefi/efi/legacy board. Some Linus OS not loading are:- --- Scientific Linux SL-64-x86_os_18 is not loading. Any advice? I am sure many thousands of Linux customers and users are having the same issues with this and equivalent motherboards from other manufacturers. thanks. [log in to unmask]
