a search function for the forums?

You should be able to enter your search query at the top right corner, then after searching, you can refine the results by choosing 'forum' as the source of the results.

Updating the RIO firmware should be straightforward - I assume you've downloaded the relevant firmware file to your PC. Then, depending on which Galil software you use, for example in GDK you go to the Setup tool, then click on the 'firmware' icon on the bottom of the screen. If you're still having issues, send an email to support@galil.com and we'll get you sorted

I'm certain there used to be a search query, but I can no longer find it on the page. I have used other browsers, but the search function doesn't appear to be available to me.
