The old pre-CAM DPT driver provided an IOCTL interface that was implemented in sys/dev/dpt/dpt_control.c, which is commented out in sys/conf/files presently. The control devices are named 'dptN' where N is the DPT controller number. sys/conf/majors:88 dpt DPT RAID Controller <shimon@i-connect.net> You're going to need to work on dpt_control.c and make it not stomp on the rest of the driver when it tries to frob the device. Good luck. On Wed, 19 Jan 2000, Jon Simola wrote: > On Wed, 19 Jan 2000, damieon wrote: > > > I administer several machines running freebsd.
