That case already gets caught by the first check:
	if ((val < 10u) || (val > 250u)) {

You remove this check, because with having both voltage checks variants it 
isn't needed, I kept it because if a reading is THAT close to the absolutely 
min / max reading possible, something is wrong.

Yes, delicate sorry. The abituguru is a microcontroller with many firmware 
versions, so what may work fine on one "chip" does not necessarily work on 
another, for example on some versions the min/max limit must be more then 1 
unit apart, which is why I use 5 and 10 resp 245 and 250.

Thanks but no thanks, I'll stick with my minimal changes version. It took me 
many days of debugging and back and forward mails with testers to get code that 
works everywhere (except appearantly your mobo).

I've also seen your do both tests in one go version, its clever, but its also 
definitively programming the "chip" outside its specs, the 2 flags should 
normally never be set at the same time. So thanks but no thanks.

p.s.

Thanks for the dmi output too.
