I'm a newbie in building pc. do motherboards have different bios version? for example the the z97 extreme 4 mobo from asrock are sold with different bios depending on release date or places?
Each motherboard has its own BIOS for it to work, z97 extreme 4s will have the same BIOS but a different model will have its own version. They're different between motherboard models, manufacturers and new BIOS version get released as BIOS updates to fix problems or improve things.
If you buy a motherboard before the next BIOS version it wont be shipped with that version since it doesn't exist yet or at least isn't available yet.
I don't think where the motherboard is matters, a motherboard from Australia should have the same BIOS as an American one, but that might not be true.
