You don't remove him from the Board, BUT you do remove him as Chairman of the Board. Most small companies still have a separation between those two roles, Chairman and CEO.
Why does he have to be Chairman of the Board as well as CEO. There are a lot of negatives to using this strategy and in recent years the tide has shifted to making this a two-person role. For myself, he should be jettisoned to the CTO position and that would be his comfort zone. As for Gumby and Bucci, hit the ejection switch.
