Then check the firmware menu (hold down Esc key during reset). Check that the SCSI bus is enabled (SCSI Patch or NCR Patch must be disabled) and check that the ID number you chose it not disabled.
I saw no mention in any of your posts that suggests that you did the above. If the ID for your device is disabled in the firmware (FlashROM settings), it will cause the symptoms you are seeing. Did you do the above that Thomas said?
