  • Page 7: Understanding Scsi

    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.

  • Page 8: Scsi Ids

    SCSI ID 7 has the highest priority on the SCSI bus. The priority of the remaining IDs, in descending order, is 6 to 0. Adaptec presets the SCSI Card 2906 to SCSI ID 7, giving it the highest priority on the SCSI bus. You should not change this setting.

  • Page 9: Terminating The Scsi Bus

    To ensure reliable communication on the SCSI bus, you must termi- nate 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.

  • Page 10: Troubleshooting

    PCI slots, select Enabled. Bus mastering must be enabled. Check your computer documentation for more information on bus mastering. – If there is an option to enable or disable individual PCI slots, be sure the slot in which you install the SCSI Card 2906 is Enabled.

  • Page 17 Select SCSI controllers on the next screen. 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).

  • Page 18: Common Error Messages

    Common Error Messages “Device connected, but not ready” The SCSI card received no answer when it requested data from an installed SCSI device. Make sure the drive is set to spin up when the power is switched on. (See the documentation for the device.) If you still have problems, you may have a bad drive.

    Scanners You must install the scanner manufacturer’s proprietary soft- ware drivers. See your scanner’s documentation for details. If the Adaptec driver loads successfully and you have problems with your system, contact your scanner manufacturer for support. You may need to make the following two system changes to help your scanner work well in your system.

  • Page 20: Installing Multiple Scsi Cards

    To use a hard disk drive previously connected to a non-Adaptec SCSI card, you must low-level format the drive after connecting it to the Adaptec SCSI card. (See Using SCSI Disk Utilities on page 19.) Caution: A low-level format destroys all data on the drive.
