Which key is to be pressed to enter Bios when the machine is connected via serial console (Board X9SCL-F)? We already tried "DEL", "F4", "F11"... but no go.
When trying to enter the bios by remote console on our X9 boards with UEFI bios, you have to press "ESC" + "-" keys at the same time. When you have a X8 board you can use "F4" to enter the bios.
