I recently installed a FastLaneZ3 into my 3000T running a v3.0 3640 and v7 buster. Fires up fine with 64 megs installed. Have yet to attempt working with the scsiII connection untill v11 buster is installed.
Double check all those Fastlane jumpers.
...and this may sound useless, but try installing the Fastlane into a different slot. I have mine just below the video slot.
good luck.
