Does the Xsurf show up in the list of boards returned by ShowConfig or the exansion list in the early start up menu??
I spent an evening playing with a Z4 board last week, and found that nothing on the busboard was recognised until I played with the jumpers ( the joys of buying second hand without manuals :roll: )
I also found that some jumper settings caused both the accelerator and the first Zorro II board to get autoconfig at the same time.. and that the boards ID was the result of both card IDs OR`d together ..which meant the driver couldn`t find the board.
