Changing UEFI setting in the firmware is a big problem. We know that a) it can only be done by tweaking settings in the firmware interface which looks different on every machine, b) users find it very hard in general, and c) for blind users it's virtually impossible.
Yeah, even as a highly-knowledgeable person, I've had to dig around to find it in some systems.
One thing I really like about Dell PowerEdge servers and OMSA is the ability to change firmware settings from within Linux with omconfig. I really wish UEFI would include a standard mechanism for that, with all the "normal" options standardized.
