Hi, I want to know that How can we know that, we need to upgrade the BIOS.
Please don't post HTML.
Upgrade the bios when you find the system has a problem that
is specifically addressed in a bios update, per the notes
the manufacturer provides. It might also help to upgrade it
when you find a bug that "shouldn't" exist, the manufacturer
might not have fully notated the bios changes per each
revision. Don't try to update the bios on a system that is
very instable, crashing may corrupt the bios and then you're
worse off... unless of course it's a last-attempt, you have
no other possibilities for resolving some problem.
Then there is a more presumptious mind-set about bios
upgrades- Usually a motherboard's early bios revisions
aren't nearly perfect, if the motherboard has an early bios
revision on it, then it might be a good idea to at least
download and archive some newer bios so that if you ever
needed to update the bios, you'd have it available.
Sometimes after boards get older the manufacturer doesn't
support them very well anymore and it's much harder to find
a bios update years later rather than within the first year
or two of it's production.
