    2. Getting Started Host Adapter and the SCSI Bus The PCI-SIU2 is a bus mastering host adapter which works with the host com- puter to provide control for the SCSI bus. By daisy chaining peripheral de- vices together, up to 15 SCSI devices can be connected to the PCI-SIU2. The host adapter can be placed in any standard PCI slot on the bus.

  • Page 14: Scsi Bus Termination

    In Windows 95/98, you can use the Device Manager to view the SCSI ID (and other details) assigned to each SCSI device installed. • Through ASUS’s SmartSCSI, you can use the utility to view the SCSI ID (and other details) assigned to each SCSI device installed. SCSI Bus Termination The SCSI bus structure has a length limitation as well as a requirement for termination at each end of the SCSI cable.

    SCSI I/O’s it is recommended to only connect LVD (Ultra2) devices to the PCI-SIU2. If a legacy device is attached to the PCI-SIU2, the devices attached will be switched to SE (Single-Ended) mode. Then all SE SCSI pa- rameters (# of devices, cable length, cable impedence) will become in effect.
  • Page 16 2. Getting Started PCI-SIU2’s SCSI termination can be set to auto-termination or programmable mode via the SmartSCSI Setup Utility. This feature allows the operator to switch the auto-termination On or Off. If auto-termination is switched Off, the operator can manually program termination for the host adapter. There are several ways to manually control terminating the host adapter on the SCSI bus.

  • Page 17: Installation Basics

    The PCI-SIU2 has one internal 68-pin high-density connector and one exter- nal 68-pin high-density connector for a combined support for 15 SCSI de- vices.

You may need to refer to the system manual for cover removal. If necessary, identify the PCI sock- ets inside the host system with the aid of the system documentation.
  • Page 19 3. Hardware Installation 4a Installation of internal SCSI devices A total of 15 SCSI peripherals can be connected to the PCI-SIU2. One internal 68-pin high density Ultra2 cable is included (see FIGURE 7). This cable is used to connect internal target devices. The internal cable is made with multiple connectors attached and used to daisy chain the host adapters to two or more target devices.

    SCSI devices can handle wide data transfer negotiations properly, which may cause system failure. Certain old CD-ROM, CD-Recordable, and tape drives cannot handle a Wide Transfer negotiation request from the PCI-SIU2 and may fail to start the system. In such cases, use SmartSCSI to disable (NO check) the Wide Negotiation setting for the SCSI ID of the anomalous device.
