Since UEFI exists, some people talk about BIOS replacement by UEFI in short-term (2011 for exemple) (see "News").
Who never has problem with BIOS bugs ? I must fight against several problems on one of my mobos because of its incorrect BIOS code, essentially for long time boot BIOS and very buggy S3 sleep mode.
However, when I read many posts about people who have installed their Windows 7 x64 in UEFI mode, I'm afraid of some new problems that UEFI causes, according to these people, even during a Windows session, even if installation was fine.
I would like to know your experience about UEFI, on motherboards which support it (my motherboard is an Intel DG45ID which proposes UEFI boot).
