Use CH341a to backup bios from one computer and write to the other?

Recommended Posts

Can I use CH341a to backup bios from one computer and write to the other of identical model? Anything to pay attention to?

 

Thanks!

Hi!

Each file bios backup contain personal computer data like:  Serial numbers for some hardware, UUID, Service TAG, NVRAM settings, MAC addresses, Windows key, e.t.c.

So, you can't use file backup bios from one computer to the other of identical model. Computer will work, but not correctly.

Hi Klem, 

 

Is there anyway I can rip out the proper ROM from computer A, and piece it together with the rest personal computer data of the other one, to make it proper flash? 

 

The two laptops are identical models. The second one has a lower version BIOS and the CPU fan keep spinning, and  the first one with higher version BIOS does not. 

 

Thanks

You can download from manufacturer website bios version you needed, and flash it into second laptop.

It is an engineering laptop and there is no public bios, so no such luck.
