Re: bios update z51 70

Hi eshwar90,


Welcome to the Community Forums.


Would there be any particular reason for a need to update the BIOS?


Checking the support site hereC2CN21WW(V2.02) released 2016/09/22 as the latest available for the model. Applying BIOS changes may cause more hard than good if not properly done so reviews on the read me file is always a good practice thus avoiding issues or even bricking the motherboard.

It would only help if fixed description applies to your issue.


Similar to BIOS this rule also applies:

The golden rule of drivers: Only update drivers when your device is NOT performing as it supposed to.It is not required to have the latest hardware drivers for every component in your computer.


To answer your query, aside from the read me file are references that you can follow:

Understanding Drivers, BIOS, UEFI and Firmware
