Overview Ultra160 SCSI on the Adaptec SCSI Card 19160 The Adaptec SCSI Card 19160 supports Ultra160 SCSI devices. Ultra160 is a new generation of SCSI technology that transfers data at up to 160 MBytes/sec. In addition to providing much greater performance, Ultra160 SCSI increases the maximum allowable cable length from 3 meters to 12 meters1 for improved connectivity and flexibility. The Adaptec SCSI Card 19160 combines this Ultra160 SCSI technology with Adaptec’s SpeedFlex™ technology.
Adaptec SCSI Card 19160 User’s Reference Understanding SCSI SCSI (pronounced “scuzzy”) stands for Small Computer Systems 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 adapter card (such as the Adaptec SCSI Card 19160) installed in a computer and one or more SCSI devices.
Overview ■ If you have 8-bit (or Narrow) SCSI devices, 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. ■ If you are booting your computer from a SCSI hard disk drive connected to the Adaptec SCSI Card 19160, the Boot Target ID setting in the SCSISelect utility must correspond to the SCSI ID of the device from which you are booting. By default, the Boot SCSI ID is set to 0. We recommend that you do not change this setting.
Adaptec SCSI Card 19160 User’s Reference 4 ■ Termination on external SCSI devices usually is controlled by installing or removing a SCSI terminator. However, termination on some external devices is enabled or disabled by setting a switch on the back of the SCSI device. ■ Some devices use automatic termination. Be sure to check the documentation for the device to be certain that the device is correctly terminated.
Troubleshooting Troubleshooting Most problems can be resolved by following the recommendations in the Troubleshooting Checklist below. If you still experience problems after following the recommendations, continue with the rest of this section. Troubleshooting Checklist Most problems with using the Adaptec SCSI Card 19160 result from errors in preparing and connecting devices on the SCSI bus. If you have problems, check these items first.
Adaptec SCSI Card 19160 User’s Reference Troubleshooting in Windows 95/98 When I start Windows 95/98, the system locks up when the Windows logo is displayed. How can I get the system to start so that I can verify that the SCSI card is functioning normally? 1 Start or restart your computer. 2 (For Windows 95:) You can force a manual fail-safe mode by pressing the F8 function key when you boot your machine while the “Starting Windows 95” message appears.
Troubleshooting 4 Double-click the SCSI controllers icon. The software driver for the Adaptec SCSI Card 19160 is listed as “Adaptec 19160, 29160(N), 39160, AHA-3960D, AIC-7892/ 7899 Ultra160 PCI SCSI Controller.” ■ If the driver is listed, the Adaptec SCSI Card 19160 driver is loading properly. ■ If the driver is listed but has an exclamation mark inside a yellow circle, the software driver may conflict with other hardware using the same resources.
Adaptec SCSI Card 19160 User’s Reference What if there is no SCSI Controller icon under Device Manager, or the software driver for the Adaptec SCSI Card 19160 does not appear under Device Manager? If the SCSI Controller icon or the software driver do not appear, first power down the system and check that the Adaptec SCSI Card 19160 is properly seated. If the problem persists, first 1 Open Control Panel and double-click the Add New Hardware icon. 2 Click Next to begin installing your new hardware.
Troubleshooting 6 7 The setting, and the hardware using the setting, are displayed. ■ If a specific resource is not listed, the resource is not used by a device. ■ If a resource is listed more than once, the resource is used by more than one device. ■ If a resource is used by an unknown device, the resource is used but the device using the resource cannot be detected. (This condition is most common.) Click Cancel to close the windows, then close Control Panel.
Adaptec SCSI Card 19160 User’s Reference Common Error Messages Here is what you should do if the following messages appear at bootup: “Device connected, but not ready” The host received no answer when it requested data from an installed SCSI device. 1 Run SCSISelect® and set the Send Start Unit Command to Yes for the particular SCSI device ID. See Starting SCSISelect on page 19. 2 Ensure that the device is set to spin up when the power is switched on. The spin up option is typically set by a jumper.
Troubleshooting “Attention! Too many devices are terminated on the SE connectors”2 The SCSI card BIOS has detected that more than two devices have been terminated on the narrow SE SCSI segment. Verify the termination on the devices connected to the internal and external connectors. Terminate only the SCSI device at the ends of the cable. Remove or disable the terminators on the SCSI devices between the ends of the cable.
Adaptec SCSI Card 19160 User’s Reference Using the Adaptec SCSI Card 19160 and SCSI Devices This section provides useful information on using the Adaptec SCSI Card 19160 and your SCSI devices. For information about a specific device, refer to the documentation for that device.
Using the Adaptec SCSI Card 19160 and SCSI Devices Using Ultra160 Hard Disk Drives ■ We recommend keeping your Ultra160 SCSI devices separate from your non-Ultra160 SCSI devices. Connecting a nonUltra160 SCSI hard disk drive to the Ultra160 SCSI connector on the Adaptec SCSI Card 19160 causes the Ultra160 SCSI segment of the SCSI bus to drop down to Ultra SCSI performance levels (40 MBytes/sec).
Adaptec SCSI Card 19160 User’s Reference Combining SCSI and Non-SCSI Devices You can install the Adaptec SCSI Card 19160 in a computer that already has a non-SCSI controller, such as an EIDE controller. However, you cannot cross-connect the disk drives and other devices: SCSI devices must be connected to the Adaptec SCSI Card 19160, EIDE devices must be connected to the EIDE controller, and so on.
Using the Adaptec SCSI Card 19160 and SCSI Devices 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, BIOS addresses, and so forth) and the systems ability to share them. ■ Each SCSI card you install forms a separate SCSI bus with a different set of SCSI devices.
Adaptec SCSI Card 19160 User’s Reference Connecting the LED Connector (Optional feature) Most computers have an LED disk activity light on the front panel of the system case. If you choose to disconnect the cable from the LED connector on the motherboard and connect it to the LED connector on the SCSI card as shown in the diagram below, the LED on the front panel of the computer will light whenever there is activity on the SCSI bus.
Configuring the Adaptec SCSI Card 19160 with SCSISelect Configuring the Adaptec SCSI Card 19160 with SCSISelect SCSISelect, included with the Adaptec SCSI Card 19160, enables you to change SCSI settings without opening the computer or handling the card.

Adaptec SCSI Card 19160 User’s Reference SCSI Bus Interface Definitions ■ SCSI card SCSI ID—(Default: 7) Sets the SCSI ID for the SCSI card. The Adaptec SCSI Card 19160 is set at 7, which gives it the highest priority on the SCSI bus. We recommend that you do not change this setting. Note: Some operating systems will not work if the SCSI card has an ID other than 7. ■ SCSI Parity Checking—(Default: Enabled) When set to Enabled, verifies the accuracy of data transfer on the SCSI bus.
Configuring the Adaptec SCSI Card 19160 with SCSISelect ■ ■ Sync Transfer Rate—(Default: 160) Determines the maximum synchronous data transfer rate that the SCSI device supports. Use the maximum value of 160 MBytes/sec. If a device is not Ultra160, select the transfer rate of the device (80, 53, 40, ...). Initiate Wide Negotiation—(Default: Yes) When set to Yes, the SCSI card attempts 16-bit data transfer (wide negotiation).
Adaptec SCSI Card 19160 User’s Reference Advanced Configuration Options Note: Do not change the Advanced Configuration Options unless absolutely necessary. ■ Reset SCSI Bus at IC Initialization—(Default: Enabled) When set to Enabled, the SCSI card generates a SCSI bus reset during its power-on initialization and after a hard reset.
Configuring the Adaptec SCSI Card 19160 with SCSISelect ■ Host Adapter BIOS (Configuration Utility Reserves BIOS Space)—(Default: Enabled) Enables or disables the SCSI card BIOS. ■ Leave at Enabled to allow the SCSI card BIOS to scan and initialize all SCSI devices. ■ Set to Disabled: Not scan if the devices on the SCSI bus (for example, CD-ROM drives) are controlled by software drivers and do not need the BIOS, and you do not want the BIOS to scan the SCSI bus.
Adaptec SCSI Card 19160 User’s Reference ■ All Disks—All removable-media drives supported by the BIOS are treated as hard disk drives. ■ BIOS Support for Bootable CD-ROMs—(Default: Enabled) When set to Enabled, the SCSI card BIOS allows the computer to boot from a CD-ROM drive. ■ BIOS Support for Int 13 Extensions—(Default: Enabled) When set to Enabled, the SCSI card BIOS supports Int 13h extensions as required by Plug-and-Play.
Connecting SCSI Devices Connecting SCSI Devices Here are some examples of how you can connect internal and external SCSI devices to the Adaptec SCSI Card 19160. To achieve maximum performance, attach the first device to the end connector (furthest from the SCSI card); attach other devices to the connectors that are closer to the SCSI card. The following example shows SCSI devices connected to all four connectors.
Adaptec SCSI Card 19160 User’s Reference The following example shows two Fast/Ultra Narrow SCSI devices connected to the external connector. As in the previous diagrams, the last device on the SCSI bus must use an SE terminator plug. Terminated device T Maximum Cable Lengths The total length of cabling (internal and external) on the SCSI bus cannot exceed the maximum lengths listed in the following table.
