Sorry, I am sort of new to FreeBSD. From what I understand /boot/device.hints gets read during boot time, the values cannot be changed by the user while the kernel is running - am I correct ? I have a loadable driver module and would like to do the following: 1. Set some tunable parameters of the driver. 2. Load the driver. Run a few tests. 3. Unload the driver. 4. repeat steps 1 thru 3. > > Larry > > -- > ============================== > Larry P.
