If your Burton board has the Channel system (two slots running lengthwise instead of traditional insert holes), you can't just bolt on any binding. You'll need either Burton's EST bindings, which are designed specifically for the Channel and offer the best board feel and cushioning, or a non-Burton binding that includes a Channel-compatible disc.
The good news is that many major binding brands now include Channel-compatible discs in the box or offer them separately. Just check before you buy — not all do. If your bindings don't come with the right disc, you'll need to purchase an adapter separately.
The Channel system does have a real upside: it gives you nearly infinite micro-adjustment for your stance width and angles, rather than being locked into fixed insert positions. This makes it much easier to dial in your perfect stance. Just don't lose those discs — they're essential for making the connection work.
