What does “bridging the unpopulated jumper” mean?

I was gifted an Acer Chromebook 314 (C934) and want to install windows on it, but I’m not sure how to go about doing the WP section as the directions are telling me to bridge a jumper and I’m not sure what that means. Any other advice for a first timer would be great!

As there are various Chromebooks with a similar name to yours on the Supported Devices page of the Chrultrabook Docs please let us know the board name. For these, it mainly looks to be that you need to disconnect the battery while installing firmware…

It’s the magneto !

As that model also has the CR50 mention there, I wonder if unplugging the battery would work in this case vs the jumper situation.
