I own an old model from around the end of 2013, but as huynhdat1989 mentioned, we will need more information.
Unless you're having a specific problem, there's not a whole ton of motherboard BIOS settings that you need to have tweaked in a certain way; many are mostly up to you.
There's no problems yet, but I just wanted to make sure that I got everything right!
So far I've disabled all audio.
I've set the Primary Graphics Adapter to "Onboard".
Render Standby is Disabled.
Onboard LAN is Disabled.
Restore on AC/Power Loss is "Power On".
Fast Boot and Boot from Onboard LAN is Disabled.
I was trying to disable the things that I wouldn't really need as far as mining is concerned. Did I overdo anything? Let me know please, thank you!
