ABSTRACT:
A system for detecting the presence and size of a SCSI device on a SCSI bus and terminating the SCSI bus accordingly. A SCSI controller is capable of driving two branches of a SCSI bus, each branch having a different data size. When the SCSI controller is at the end of a SCSI chain, termination is enabled, otherwise termination is disabled. Termination is performed on the portions of the SCSI data bus requiring termination based on the presence and size of SCSI devices on the branches used.
