Yep, definitely Infinity. See that "create" link there? vichan does not have a way for users to create boards, that's an admin feature only (for better or for worse).
The boardlist (the top row with links to boards or whatever you want) is not an Infinity-exclusive feature, fss guise
It's there in the native Vichan code. Just look for "boardlist" in your config files, it should be there somewhere. Was almost a year since I did a fresh install so I can't tell you exactly how to get it.
Welp it's been 7 fuckin months and nobody replied, so I assume you figured it out, but for anyone else who cares, you just need to set $config['boards']. It should be a multi-dimensional string array with names of boards to display (each array corresponds to a "category" wrapped in a separate pair of square brackets), e.g.:
$config['boards'] = array(array('g1b1', 'g1b2', 'g1b3'), array('g2b1', 'g2b2'));
This would lead to the following being displayed at the top:
[ g1b1 / g1b2 / g1b3 ] [ g2b1 / g2b2 ]
