Not quite. Newbus provided (and still provides) a compatibility layer which allows most driver written to the old apis to work unchanged. > For the same reason you > can't get the commercial OSS thing for FreeBSD-4.x/5.x. The reason that OSS does not work in 4.x is that OSS uses an interrupt registration interface which has been deprecated since approximately FreeBSD 2.2. There are suitable replacement interfaces which integrate properly with the resource management systems of the kernel but the OSS engineers chose not to change their driver to with with the new system. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
