ssl for nginx, old browsers

[eternity]

So, i made a bit progress
I took chrome which doesn't ask for risk, and exported chain
So, now, old version asks only once to add root CA and then it becomes silent
Now the question - how to add one more element in chain so old browsers won't even ask for adding CA
