Understanding SCSI SCSI (pronounced “scuzzy”) stands for Small Computer System Interface. SCSI is an industry standard computer interface for connecting SCSI devices (such as a hard disk drive, CD-ROM drive, or scanner) to a common SCSI bus. A SCSI bus is an electrical pathway that consists of a SCSI card (such as the SCSI Card 2906) installed in a computer and one or more SCSI devices. SCSI cables are used to connect the devices to the SCSI card.
SCSI Card 2906 User’s Reference SCSI IDs You must assign a unique SCSI ID number from 0 to 7 to the SCSI Card 2906 and to each SCSI device attached to the SCSI Card 2906. A SCSI ID uniquely identifies each device on the SCSI bus and determines priority when two or more devices are trying to use the SCSI bus at the same time. Refer to the device’s documentation to set the SCSI ID.
SCSI Card 2906 User’s Reference Terminating the SCSI Bus To ensure reliable communication on the SCSI bus, you must terminate both ends of the SCSI bus. If the SCSI Card 2906 is connected at one end of the SCSI bus, you must still terminate the device at the other end. Termination prevents the signal from bouncing off the end of the cable and interfering with the original signal.
SCSI Card 2906 User’s Reference Troubleshooting Troubleshooting Hardware Checklist Most problems with the SCSI Card 2906 result from errors in preparing and connecting devices on the SCSI bus. If you have problems, check these items first: ■ Are all SCSI devices turned on? ■ Are all SCSI cables and power cables properly connected? ■ Is the SCSI Card 2906 firmly seated and secured in the PCI expansion slot? Turn OFF the power to the computer before checking the card.
SCSI Card 2906 User’s Reference – If your computer has a combination of ISA or EISA boards and PCI boards, you may need to mark the IRQs used by ISA/EISA boards as Used so the computer BIOS will not try to assign these IRQs to other PCI boards. Never use an IRQ below IRQ9 for a SCSI card. Some configuration options apply to a specific PCI bus slot, so if you change any option, be sure you are applying the change to the correct slot.
SCSI Card 2906 User’s Reference ■ If the driver is listed but has an exclamation mark inside a yellow circle, the software driver may be in conflict with other hardware using the same resources. Double-click the icon to see the device status and possible solutions. ■ If the driver is listed but has an “X” inside a red circle, the SCSI Card 2906 software driver is disabled and isn’t loading (see below). ■ If the SCSI Controller icon or the SCSI Card 2906 driver is not listed, reinstall the driver.
SCSI Card 2906 User’s Reference In Windows 95/98, why is there a yellow ! beside my driver(s) in Device Manager? The yellow ! may appear for many reasons. Use Table 1 to troubleshoot this problem. Some of the reasons are listed by level of difficulty, the first being the easiest to solve. Table 1. Troubleshooting Table.
SCSI Card 2906 User’s Reference If the first message (a) appears, click the Details button in the Performance tab for more information. If needed, contact your computer manufacturer for additional help. If the second message (b) appears, you must update or install the driver. For information on downloadable drivers, refer to the Adaptec Web Site http://www.adaptec.com/support/index.html. Click on the Drivers section for more information on how to download the correct driver.
SCSI Card 2906 User’s Reference 5 In the Computer Properties window, click Interrupt request (IRQ), as shown in the following sample screen. The Settings column lists the IRQs in use. IRQ settings range between 0 and 15. If an IRQ setting is not listed under Settings, this means it is available. In the screen above, setting 10 is not listed and, therefore, is an available IRQ. Note: Do not use an IRQ below IRQ 9 for a SCSI Card 2906.
SCSI Card 2906 User’s Reference In Windows NT 4.0, where can I check which resources are available on my computer? Note: You must log in as an Administrator to complete the following steps. 1 Click the Start button, point to Programs, point to Administrative Tools, select Windows NT Diagnostics and then click Resources Tab. 2 Select the resource from the Used Resources list, for example IRQ, DMA, etc. 3 In the SCSI Adapters window, click the Properties button to find which resources are in use.
SCSI Card 2906 User’s Reference 2 In the second screen of the wizard, click No. 3 Select SCSI controllers on the next screen. 4 Select the model of your Adaptec SCSI Card. If SCSI Card 2906 is not on the list, you may be able to install a SCSI card driver from the Windows 95/98 CD-ROM (or from the Adaptec EZ-SCSI Setup Diskette).
SCSI Card 2906 User’s Reference How do I use the Hardware Conflict Troubleshooter in Windows 95/98? 1 Click the Start button, then click Help. 2 From the Contents tab, double-click Troubleshooting. 3 Double-click If you have a hardware conflict. 4 Follow the step-by-step instructions in the Windows Help window. Common Error Messages “Device connected, but not ready” The SCSI card received no answer when it requested data from an installed SCSI device.
SCSI Card 2906 User’s Reference Using the SCSI Card 2906 and SCSI Devices This section provides useful information on using the SCSI Card 2906 and your SCSI devices. For specific information, refer to the documentation that came with your SCSI device. Using SCSI Devices Hard Disk Drives ■ You cannot boot your computer from a drive connected to the SCSI Card 2906. To boot your system, a bootable hard disk drive must already be installed on a different SCSI card or IDE card.
SCSI Card 2906 User’s Reference Installing Multiple SCSI Cards ■ You can install multiple SCSI cards in your computer; you are limited only by the available system resources (for example, IRQ settings, I/O port addresses, etc.) not used by other cards installed in your computer. ■ Each SCSI card you install forms a separate SCSI bus with a different set of SCSI devices.
SCSI Card 2906 User’s Reference Configuring the SCSI Card 2906 with SCSISelect SCSISelect (included on a separate diskette in your package) enables you to change SCSISelect settings without opening the computer or handling the card. SCSISelect also enables you to low-level format or verify the disk media of your SCSI hard disk drives. Table 2 lists the available and default settings for each SCSISelect option. Note: The default settings are appropriate for most systems.
SCSI Card 2906 User’s Reference Starting SCSISelect Follow these steps to start SCSISelect: 1 Turn ON or restart your computer. Allow it to boot to a DOS prompt. 2 At the DOS prompt, insert the SCSISelect diskette and change to the a:\ prompt. 3 At the a:\ prompt, type 2906cfg.exe. 4 From the menu that appears, use the ↑ and ↓ keys to move the cursor to the option you want to select, then press Enter.
SCSI Card 2906 User’s Reference Using SCSISelect Settings To select an option, use the ↑ and ↓ keys to move the cursor to the option, then press Enter. In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing Esc. To restore the original SCSISelect default values, press F6 from the main SCSISelect screen. SCSI Bus Interface Definitions ■ Host Adapter SCSI ID—Sets the SCSI ID for the SCSI card.
SCSI Card 2906 User’s Reference SCSI Device Configuration Note: To configure settings for a SCSI device, you must know its SCSI ID (see Using SCSI Disk Utilities on page 19). ■ Initiate Sync Negotiation—When set to Enabled, initiates synchronous data transfer negotiation (Sync Negotiation) between the device and SCSI card. Leave this setting enabled unless any attached SCSI device connected to the SCSI card does not support synchronous negotiation.
SCSI Card 2906 User’s Reference Using SCSI Disk Utilities To access the SCSI disk utilities, follow these steps: 1 Select the SCSI Disk Utilities option from the menu that appears after starting SCSISelect. SCSISelect scans the SCSI bus to determine the devices installed and displays a list of all SCSI IDs and the devices assigned to each ID. 2 Use the ↑ and ↓ keys to move the cursor to a specific ID and device, then press Enter.
SCSI Card 2906 User’s Reference Obtaining SCSI Cables High-quality cables are required in high-performance SCSI systems to ensure data integrity. Adaptec provides the highest quality SCSI cables designed specifically for use with Adaptec SCSI cards. For purchasing information, see page 24.
