Bios Flashing

I've got theAsusP8z77-vMotherboard with revision Board: ASUSTeK COMPUTER INC. P8Z77-V Rev 1.xx

The page for Asus support says an update is available : P8Z77-V BIOS 1606, but it also says that there is a risk of data loss.

So, the questions is : Should I or Shouldn't I...

The standard advice is no you should not UNLESS you are having problems that you have GOOD REASONS to believe will be resolved by the new BIOS. Not hope, not possibly, not maybe, not "well, it can't hurt", etc.

Those good reasons might come from a specific mention on the Asus site that a new BIOS solves issues X, Y, or Z. Or possibly solid research on the net. But not guessing/hoping.

The risk includes the possibility of having to buy a new motherboard if the flash doesn't go well----power failure, you make an incorrect decision due to lack of experience, etc.

BIOS flashing problems aren't as easily recovered from as driver updates for example. "Rolling back" to an older BIOS may not be in the cards at all.

I totally agree with ignatzatsonic. Updating bois just because their/there is a new one is not wise.

Sysfan:

Do you know if it works properly on your PC?

I have a Gigabyte board with dual BIOS also. But----the recovery block cannot be brought up when needed. It's useless in my case. I've heard of others with a similar problem and am wondering how common it is for the dual BIOS to work as advertised?

It worked like this-- I had the rev 1.1 version of the B75M D3H, but flashed the rev 1.0 version by mistake. Surely enough, the PC failed to boot up, and it automatically rebooted itself about 2 times and made funny noises, and it reverted to the BIOS which was saved in the recovery block.
The main block is 100% re-writable, but the Recovery block is impossible to write onto :)
