I just got a DKB 4091 and installed it into my A4000D/040 (Buster 11). The board is recognized but when running HDToolbox (using 2nd.scsi.device) or the HD partitioning program from the installation floppy I get an hour glass. I've tried with and without hard drives and get the same result.
Any ideas? I do not have the manual so I don't know if anything has to be changed on the A4000 motherboard.
