Hi all,

I have an Asus Z170-K mobo with BIOS version 2.17.1246. I'd like to be able to disable the DVD drive as a boot device via the BIOS but, despite appearing to disable it, whenever I have a bootable disc in the DVD drive, the machine will boot to it.

I've chosen "disabled" for the DVD drive under "Boot" in the advanced mode.

Have I missed a trick?

Many thanks.
