one being relating to screen brightness. If I set a low default screen
brightness in Windows then it seems to change the range of brightness
Linux can display. This was even more noticable when running LiveUSB
distros! I actually couldn't get the screen bright enough to see what I
was doing without setting the level within Windows bright again!
Is there a setting in regular bios for screen brightness? EFI my leave
some variables around that the OS can continue to manipulat after boot...
wonderful :P
Then I read (or skimmed) this yesterday and feel even
more confused.

I see what you mean, every time I thought I was getting somewhere, I got
sent to yet another page. The most I got out of it was that EFI is intel's
answer to grub but with more control of the firware settings at the same
time. The old bios included calls to access some of the HW, but no one
used them as they were not muti-task/user friendly. It appears EFI does
the same thing and windows uses it and Linux does not know how to access
at least part of it. (or windows sets up its own calls within it)
But I am starting to think I should try enabling it
with a Linux
install. Especially as I plan to completely banish Windows from the
computer now... But I thought I would ask what more experienced Linux
users have to say about UEFI mode vs BIOS/Legacy mode.
You will get some I don't doubt... it may be hard to tell the truth from
FUD ;) EFI and Linux are still relatively new (3.10ish) and complaints
found in one kernel version may no longer be true.
