Update SeaBIOS (on Deciso Netboard A10)?

[Lambeth]

Hello

I have a "Desktop & Wallmountable" firewall which I bought from [applianceshop.eu] a few years ago.

The bios on the device is somewhat old now and I'm thinking about updating it, currently it seems to be SeaBIOS version 1.7.5-20141105_115023-ubuntu.


Some questions:

• Would there be any benefits in updating the bios?
  Of course it's always nice to have up-to-date software just for its own sake, but should I expect there to be any real/actual benefits I could notice?

• How would an update be performed?

• Is it risk-free to try updating the bios... or could there be a risk that the hardware gets bricked?

• Has anyone here got experience doing a more-or-less similar update? Perhaps even updating on this exact hardware?

Thanks for your help 

Below is an excerpt from the boot of my firewall which shows some information:
