Where is located those terminators? I didn't find any manuals how install hard drive or SCSI board description... I think my CD drive terminated in the end otherwise it could not work with other samplers. I changed ID number to 5 in CD-ROM and now S1100 read CD disk successfully, I guess that 5 is default number when system start and scan for ext hard drive... owner's manual says when install internal HD the number must be 5, so I connected external CD drive to SCSI card and it works only with ID 5.
