How to enable "Write to BIOS"

I have a Lenovo 100s 80QN. I would like to enable "write to bios" but I cant find a teardown of it anywhere. Can anyone help me so that I don't damage my device?

Re: How to enable "Write to BIOS"

You normally run an update program that enables writing to the BIOS, writes the update to it, then disables the ability to write to it. Writing to it by yourself will leave the Chromebook unbootable, unless you know how to write system firmware - in which case you can just debug the ROM to find out where the write enable bit is - and change it.
