First, please be guidede that BIOS updating is actually one procedure that we highly do not just recommend owners to do on their own unless they are willing enough to take the risk of having the possible breakdown and harm that BIOS updating can do which is no longer reversible and will totally damage the board. Now as for the BIOS contents if you will notice in the selection portion of our website for drivers support, each models are specified in different variants which carry different hardware package where some has the NVIDIA and the other does not have NVIDIA but regardless of the model under the V3-575 series you select, they all carry the same BIOS versions. The BIOS developer is only stating that the said version already carry the new BIOS version for the unit who uses the Nvidia 920M GPU and if not it will not be of use.
