As my father would have said "what in tarnation is this for?"
What is the purpose of this in other words? I have been looking into it and can see how it is configured and so forth but really can't come up with any real use for it that seems to make sense.
Just a bee in my bonnet caused by reading this stuff;
Which seems to be people getting their knickers in a knot just so that they walk funny.
Was a bit taken aback by that stuff. Don't think "firmware" upgrades are generally all that important at that level. And I was able, with a bit of struggle to actually do a bios upgrade on the Dell without Win installed on it. My Asus MB uefi is capable of being upgraded running only in the uefi system and I assume, perhaps incorrectly, that this is a fairly common feature for efi/uefi systems.
But it did get me to realize that this file exists and I would really like to know what it actually is for.
