Drive Select ------------ The DS jumper is used to identify the drive as a MASTER drive in a single or dual drive configuration. This is the factory default setting. Slave Present ------------- The SP jumper is only used when the second drive in a two drive configuration does not support DASP. DASP (Drive active/drive 1 present) is a CAM (Common Access Method) defined signal that indicates the presence of a second drive, DASP is used during power on initialization and after a reset. Prior to this definition, products were introduced which did not utilize this method to detect the presence of a second drive. The SP jumper is only used on the Master drive, with the DS jumper, when the second drive does not support DASP. Cable Select ------------ The CS (Cable Select) jumper is only used in systems that support this feature. Cable Select allows for each IDE disk drive to be jumped the same and the position on the cable determines the ID. This requires special cable and both drives on the interface would have to support this feature. ********************************************************************** F E A T U R E S ********************************************************************** QUANTUM TRAILBLAZER/FIREBALL Plug-and-Play firmware (AT Bus Cable Select for Fast ATA drives and Plug-and-Play SCSI for Fast SCSI drives) simplifies disk drive installation by automatically configuring Trailblazer drives and eliminating the need for any manual jumper settings.
