Demo boards are often so "chuck-full-of-nuts" (features) that really get in the way more than they help. Often they're on the board because they're easy to include and therefore advertise, rather than to use. I've seen numerous FPGA as well as MCU boards with PS/2 ports and VGA ports, yet no real support in the form of functional drivers that work together. Just because a board has the ports for keyboard, display, and mass storage of one sort or another doesn't mean they will all work together, or even fit in the available storage. The only real solution with an evaluation kit is to ensure it comes with a complete OS implementation that runs on conventional hardware, e.g. keyboard, monitor or satisfactory display panel, and conventional mass storage capable of supporting the OS, and not just via network, as that adds extra burden.

In short, thoroughly read and understand the documentation, including the "fine-print", and not just the first page.
