The Onboard Device Configuration lets you enable/disable various on-board peripherals, hence the title.
Its a bit of a waste to have a whole menu screen dedicated to just saying Yes/No to PnP OS
And we have a USB Configuration screen:
The Boot menu sets boot options and priorities:
The Power Menu controls APM settings, and gives us access to the hardware monitor
I really like OC Profiles on the EZ Flash 2 screen; I just wish it was possible to save more than two profiles. Having the option to name said profiles would be even better.
And of course we can save or discard changes, and load defaults from the Exit menu.
