Hi.
I have a problem with this Mobo. I have several rigs with USB with linux like SO. Sometimes when a rig hangs and reboot the mobo enter directly at BIOS continously and don't recognize USB pendrive. The only solution is change pendrive of USB port and mobo restart without problem. This is a problem for to restart the rig remotely.
Why happend this? What is the solution?
Thx.
Look for legacy support options in the bios of the mobo. Try with legacy boot ON and everything else off. This worked for me in the past.
I do not have this motherboard anymore so I can not give you specific directions, sorry.
