Is there a way to access BIOS on a used Lenovo Ideapad G580 2689 ?

Problem solved - the BIOS was simply out-of-date ...
The problem was not helped by the Lenovo PC support site listing the wrong BIOS update i.e. 5ecn96ww, following entry of the laptop's serial number for a Win8.1 setup (this update is for Win7!).  >

Finally, I found the correct version, i.e. 62CN97WW, to replace the 62CN90WW already preinstalled on the Lenovo G580 2689. Once the BIOS had been flashed, the BIOS, Boot Order, etc, could be readily accessed, using either the novo button or the F2-key.

DeepThought, I did try the novo software & other link you kindly provided - many thanks for those.  Needless to say, they didn't work but the BIOS update fixed everything. Therefore, it seems that the novo button doesn't need any special software to enable it - useful to know in itself. 

For the many others out there who appear to have been confounded by the same problem of not being able to access the BIOS or Boot Order on a Lenovo G580 2689, the following link for the BIOS update 62CN97WW may be useful:

Now that I can access the BIOS and Boot Order, I can now go ahead and do a Legacy dual-boot install for  LL / Win8.1 ...  8)
