1. Many want such but want a free bios. mrbios.com and other sites may have what you want for a price.
2. I found it cheaper to toss the board out and get one that was better all around.
In closing, many of the Dell/HP/other designs have these settings cast in stone (or silicon) so don't bother wasting too much time on such boards.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
