I did not say optimal.exe is useless. I used it more than once! BTW, it is broken, as it only works in certain MB, DPT, firmware combinations. I am going to add it to the DPt driver. Then it will be an option in dptcntl. ... > Just out of curiosity I would be interested in what a DPT set would cost: > controller > cabinet for 5 disks > 4*4Gb disks in canister > cables I belive the shelf for 8 disks is about $2,300, the disks 9in a canister are about $100 over mail order prices. The shelf comes with one cable and two powersupplies, and two fans and an automatic differential/SE interface and two terminators.

The difficulty arises from the close ties /dev/dpt has to the HAS work I am working on. Even worse is the certification process. Before I will release this code, I need to spend several weeks in regression testing. I simply do not have the time right now. There is pressure to move the DPT driver to CAM, and to continue with the HAS work. ... > I have some stuff in a DPT/tools directory, but they do not seem to work. > First I had to change from major devno 130 to devno 88, but still no go. > I'm starting to wonder if my mirror of your DPT directory is still > operational? Where do you currently keep your FreeBSD work? The major number is a NOP. The latest work is in ftp://simon-shapiro.org/crash.
