F20 on my Lenovo x120.  It was a mess, as the write of the efi cruft 
failed.  What it took to get it to work was scary.  Supposedly what we 
learned from my misadventure has been 'fixed' with F21.  I have a Lenovo 
x120 just waiting here for me to test, but I first have to build a local 
repo, as they have elminated the full DVD with only netinstall which is 
a pain for those of us with DSL.

We have lived with PC Bios for a long time.  I actually like this 
developing uboot process for right now.  Does remind me of all the times 
I needed to book with a DOS diskette and load a new Bios file to fix 
some Bios bug.  In fact, I had to do this just last year.

I started on PCs in '83 and ran DOS 1.0, and went from there.  Linux 
came MUCH later.

But enough remembering how it was.  Peter did point out what we have to 
deal with the current SOCs and this is not likely to change for some 
time.  For them, if they can get Android working, that is enough to ship 
their chip.
