Hi Justin and everyone, I just made a kernel with the new CAM code that includes ncr support and this is what I get with "boot -v". It works (this message is sent with a system running kernel.cam) but I don't understand the messages below... Why are the two 34330W IBM drives running with a speed of 6.6 MB/s while the 32160 is found as an ultra drive at 20 MB/s ? The conner is also found at 3.3 MB/s when it should probably be at 10 MB/s (or I have misunderstood what the numbers say). My current config found by the old code is appended below.
