1. Introduction 1 The ASUS PCI-SIU2 Host Adapter The ASUS® PCI-SIU2™ is a high-performance Ultra2 (Low Voltage Differential) PCI bus master host adapter which provides the interface between the SCSI bus and the PCI local bus. The PCI-SIU2 supports 32-bit data transfers across the high bandwidth PCI bus at speeds up to 133 Mbytes per second.
1. Technical Illustration SE ASUS PCI-SIU2 LVD TERM ACT FIGURE 1 identifies major components pertaining to your PCI-SIU2 host adapter. You will find it helpful to refer to this illustration while installing the host adapter and attaching the cables.
1. Product Features/Specifications Product Features • PCI Compatibility: The PCI Bus is a 32-bit bus with multiplexed address and data lines. The PCI-SIU2 is compliant with PCI 2.1 bus protocol, electrical and mechanical specifications. • Plug and Play: The PCI-SIU2 has an on-board read only memory (ROM) to provide the necessary configuration mechanisms for installation, configuration, and booting without user intervention.
Product Features/Specifications • 256-byte FIFO: A 256-byte FIFO buffer is designed into the PCISIU2 and is utilized as a caching buffer to manage PCI to SCSI bus structure timing for data and command transfer. • Command Queuing: A unique implementation to provide 255 simultaneous SCSI commands.
2. Getting Started 2 Host Adapter and the SCSI Bus The PCI-SIU2 is a bus mastering host adapter which works with the host computer to provide control for the SCSI bus. By daisy chaining peripheral devices 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. SCSI Bus Preparation Peripheral devices attached to the SCSI bus can either be an internal or external device.
2. Getting Started • If you have 8-bit SCSI peripherals, they must use SCSI IDs 0, 1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first SCSI hard disk drive. • 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.
2. Getting Started Mixing UltraSCSI &U2 (LVD) SCSI Devices The PCI-SIU2 supports legacy drives. However, in order to maximize performance of 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 parameters (# of devices, cable length, cable impedence) will become in effect.
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. The following is a sampling: SCENARIO 1 INT.
3. Hardware Installation 3 Installation Basics The internal cable permits connection of multiple internal devices. SCSI devices that are connected to the internal connector are installed inside the host computer enclosure. The external connector is accesible through the D-shell connector at the back of the host system and is designed to connect devices outside the host system enclosure.
3. Hardware Installation Installing the PCI-SIU2 Host Adapter 1 Power down the host computer and all peripherals Remove the cover from the host system. You may need to refer to the system manual for cover removal. If necessary, identify the PCI sockets inside the host system with the aid of the system documentation. 2 Use static electricity discharge precautions Remove possible static discharge potential from any objects that the host adapter may come in contact with before installation.
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. The connector on the host adapter is keyed for proper orientation and insertion.
3. Hardware Installation 4b Installation of external SCSI devices Use the 68-pin external Ultra2 SCSI connector to connect your external Ultra2 peripherals. Ultra2 external cables are not included in the kit. Installation of external SCSI cables can be performed after the cover has been closed. The cable is limited in length to a total of 12 meters including any internal cabling. The external cable can be daisy chained to include up to 15 devices with the host adapter in combination with internal devices.
3. Hardware Installation 5 Drive activity LED A drive activity LED is designed into the host adapter to indicate when a data transfer is being made. Connection to the LED is optional and cabling is not included with this kit. Each host adapter has one four-pin connector. Please refer to the host adapter’s illustration (FIGURE 10) for the LED connector that will accomodate the LED cable.
3. Hardware Installation 8 System startup The newly installed SCSI bus is now ready to power up. Switch on peripheral and host computer system power. The system monitor should display the following information, but may vary, based on the system BIOS manufacturer. • The normal Power-On Self Test and memory test procedure. • The host adapter sign on message including a list of attached SCSI devices. The list should match the peripheral devices attached to the bus.
3. Hardware Installation If both SCSI and non-SCSI (for example, IDE) disk drives are installed, then the non-SCSI disk drive is typically the boot drive. If your computer supports BBS (BIOS Boot Specification), both SCSI and non-SCSI disk drives can coexist and you can specify which drive to boot from. Refer to your computer documentation for more information. Low-level Format A low-level format will erase any data that is stored on the target disk.
3. Hardware Installation the host adapter has a jumper that can be enabled (closed) to set the active onboard termination on all the time, regardless of whether power is applied or not. The host adapter is shipped without the jumper installed and need not be changed in most cases. Visually inspect the configuration you have installed to verify that all cables have been inserted correctly.
4. Host Adapter Setup 4 Running the SmartSCSI Setup Utility To start the SmartSCSI Setup Utility, verify that all devices attached to the SCSI bus are powered up when the host computer system is turned on.

4. Host Adapter Setup Main Menu Options SmartSCSI’s main menu provides five possible setup options for meeting your system configuration: Scan Bus Choosing this option results in the host adapter utility to scan the SCSI bus to determine peripheral devices attached to the host adapter. All device ID’s are displayed on the screen including SCSI ID’s without devices attached. This allows for a better definition of location and priority on the SCSI bus.
4. Host Adapter Setup Spin Up Disk Drive. This option is used to initiate motor spin-up for SCSI disk drives. The host adapter BIOS can limit system power requirements during power-up. This is accomplished by signaling the device to start at delayed intervals (default setting will be ‘No’). Enable Disconnect. The host adapter uses this option to allow a device to temporarily disconnect from the SCSI bus (referred to as disconnect/reconnect).
4. Host Adapter Setup BIOS Setup Enable Host Adapter BIOS. This option controls the host adapter usage of SCSI disk I/O routines inside the host adapter BIOS. By disabling this option you will eliminate the host adapter’s ability to utilize boot capabilities in PCISIU2. Setting this to “no” will also disable all subsequent features displayed by this on-screen panel. The default setting will be on. (Yes) Boot Device ID. This option selects which SCSI device will be the designated boot device for the system.
