Zubkoff 199for writing such a complete and well documented Mylex/BusLogic MultiMaster 200driver for Linux. 201Support in this driver for the wide range of MultiMaster 202controllers and firmware revisions, with their otherwise undocumented quirks, 203would not have been possible without his efforts.
