Anyone know anything about it? It is like having two bios chips that you can flash with two different bios versions and then switch between them manually?

I think its more like if setup an over-clock that fails and you cant boot. It will boot the second or backup bios to make it run and when you adjust your changes it does it on the first bios. If I understand correctly the second bios is like a stock or failsafe.
Dual bios is just that two bios chips.
I've only dealt with AM3 boards but on those one you can flash the other you can't. Basically fail safe like djbess said but for a bad bios flash.
Can you choose which BIOS is used or does the board decide itself after a failed post?
As far as their AM3 boards no you can't choose which one but on the board they are labeled M for main and B for backup. Also you can't physically change them unless you unsolder/solder them but that makes no sense to do.
The backup kicking in is an automatic thing. Updating is also automatic.
I don't trust "automatic."
think of it as a backup bios chip incase you fuck up when you are updating the original, if you blow your first bios chip up then the other one kicks in.
There is nothing on the user end you can do, other than blow up your bios chip to make it kick in.
if you do bork your bios you will thankful for the automatic.
I like the idea of a backup bios but I want control.
I would much prefer a jumper on the board to select between chips.
I'd even like a socketed chip on the board and a spare pre-programmed chip included along with the sata cables and such.

I never thought this would be a plus and didn't realize Asus did this until I was trying to get a Asus 890GX board working by replacing the bios. Only then did I realize this wasn't something new for them and was on my P6T6 board.
I had some weird thing go on my 790FX Gigabyte board where it was reflashing the back up while I was working on an overclock and just running memtest 86+ to work out the memory errors. Was really weird but it eventually stop.
A good number of current Biostar 880 and 890 boards have a socketed bios. I can't say that every Biostar board has it, but all of the ones I've looked at have had it.
i was referring solely to Gigabyte brand
I'm not worried about bricking boards. There are places to buy pre-programmed chips. I have an smd rework station so I can replace even unsocketed bios chips.
I'd like to flip between two different perfectly working bios's as I wish. It sounds like Gigabyte's "automatic" switching will not allow that.
Do all Asus boards include an extra bios chip?
And this is why I'm skeptical about "automatic" anything in a bios. Bios code is not exactly the pinacle of software engineering. It's ususally a mess.
Hmm, read over on overclock.net that pressing F7 will (I think) update the back up bios.
