Understanding SCSI

SCSI (pronounced scuzzy) stands for Small Computer Systems Interface. SCSI is an industry standard computer interface for connecting SCSI peripherals (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 SCSI Card 2940U2W) installed in a computer and one or more SCSI peripherals. SCSI cables are used to connect the peripherals to the SCSI adapter card. For the SCSI bus to function properly, SCSI IDs must be assigned to SCSI devices (SCSI peripherals and SCSI card), and the SCSI bus must be properly terminated.

SCSI IDs

Each peripheral attached to the SCSI Card 2940U2W, as well as the SCSI Card 2940U2W itself, must be assigned a unique SCSI ID number from 0 to 15. A SCSI ID uniquely identifies each SCSI 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 peripherals documentation to set the SCSI ID. Here are some general guidelines for SCSI IDs:
For internal SCSI peripherals, the SCSI ID usually is set by configuring a jumper on the peripheral. For external SCSI peripherals, the SCSI ID usually is set with a switch on the back of the peripheral.
SCSI ID numbers dont have to be sequential, as long as the SCSI Card 2940U2W and each peripheral has a different number. For example, you can have an internal SCSI peripheral with ID 0, and an external SCSI peripheral with ID 6. Gaps in the sequence of numbers dont matter. SCSI ID 7 has the highest priority on the SCSI bus. The priority of the remaining IDs, in descending order, is 6 to 0, 15 to 8. The SCSI Card 2940U2W is preset to SCSI ID 7 and should not be changed. This gives it the highest priority on the SCSI bus. Most internal SCSI hard disk drives come from the factory preset to SCSI ID 0. 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. If you are booting your computer from a SCSI hard disk drive connected to the SCSI Card 2940U2W, the Boot Target ID setting in the SCSISelect utility must correspond to the SCSI ID of the peripheral from which you are booting. By default, the Boot Target ID is set to 0. See Boot Device Options on page 18 to change the Boot Target ID. In Windows 95, you can use the Device Manager to view the SCSI ID (and other details) assigned to each SCSI device installed. If you installed Adaptec EZ-SCSI software, you can use the SCSI Explorer utility to view the SCSI ID (and other details) assigned to each SCSI device installed.

SCAM Protocol

The SCSI Card 2940U2W supports the SCSI Configured AutoMatically (SCAM) protocol, which assigns SCSI IDs dynamically and resolves SCSI ID conflicts automatically when you start the computer. If your computer includes SCSI disk drives or other peripherals that support SCAM, you do not need to manually assign SCSI IDs to these peripherals. To enable SCAM support, see Configuring the SCSI Card 2940U2W with SCSISelect on page 15.

Terminating the SCSI Bus

To ensure reliable communication on the SCSI bus, the ends of the SCSI bus must be properly terminated. This is accomplished when the peripheral at the end of each cable, or the end of the cable itself, has a terminator installed (or enabled). The peripherals between the ends of each cable must have its terminator removed (or disabled). Since the method for terminating a SCSI peripheral can vary widely, refer to the peripherals documentation for instructions on how to enable or disable termination. Here are some general guidelines for termination:
Termination on internal SCSI peripherals usually is controlled by manually setting a jumper or a switch on the peripheral, or by physically removing or installing one or more resistor modules on the peripheral. Termination on external SCSI peripherals usually is controlled by installing or removing a SCSI terminator. On some external peripherals, termination is controlled by setting a switch on the back of the drive. By default, termination on the SCSI Card 2940U2W itself is automatic (the preferred method). To manually set termination on the SCSI Card 2940U2W, see Configuring the SCSI Card 2940U2W with SCSISelect on page 15. Internal Ultra2 peripherals are set at the factory with termination disabled and cannot be changed. Proper termination for internal Ultra2 peripherals is provided by the built-in terminator at the end of the Ultra2 internal SCSI cable. Most non Ultra2 SCSI peripherals come from the factory with termination enabled.

Troubleshooting

Most problems can be resolved by following the recommendations in Troubleshooting Checklist below. If you still experience problems after following the recommendations, continue with the remainder of this section.

Troubleshooting Checklist
Most problems with using the SCSI Card 2940U2W result from errors in preparing and connecting peripherals on the SCSI bus. If you have problems, check these items first.
Note: If you have problems with a specific SCSI peripheral
when other connected SCSI peripherals are working correctly, please contact the manufacturer of the problem peripheral for troubleshooting information.
Are all SCSI peripherals turned on? Are all SCSI cables and power cables properly connected? Is the SCSI Card 2940U2W firmly seated and secured in the PCI expansion slot? Is the PCI expansion slot PCI Rev. 2.1 or higher compliant and does it support Bus Mastering? Are all SCSI peripherals and the SCSI Card 2940U2W assigned unique SCSI IDs? (See Setting Up SCSI Peripherals on page 3.) Are all SCSI peripherals terminated properly? (See Setting Up SCSI Peripherals on page 3.) If your computer allows you to set up configuration options when the computer first boots up (that is, through CMOS setup), are the following options set up as specified?
If there is an Interrupt Type or Interrupt Line option in the Setup program, select Int-A or Interrupt Type = A (you may also be required to change a motherboard jumper setting). If there is a Triggering Interrupt option, select Level.
If there is an option to enable or disable bus mastering for the PCI slots, select Enabled. If there is an option to enable or disable individual PCI slots, be sure the slot in which you install the SCSI Card 2940U2W is Enabled. 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. In some computers the BIOS reserves a set of available IRQs for PCI boards, and you have to assign these IRQs manually.
Note: 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. Check your computer documentation to determine the correct PCI bus slot.
Troubleshooting in Windows 95
When I start Windows 95, 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?

What if there is no SCSI controller icon under Device Manager, or the software driver for the SCSI Card 2940U2W does not appear under Device Manager?
If the SCSI controllers icon or the software driver do not appear:
Double-click the Add New Hardware icon in Control Panel. Select Yes on the second screen of the Add New Hardware Wizard to have Windows search for the SCSI Card 2940U2W. Follow the onscreen instructions.
If Windows 95 does not detect the SCSI Card 2940U2W, run the Add New Hardware Wizard again:
Double-click the Add New Hardware icon in Control Panel. Select No on the second screen of the wizard. Select SCSI controllers on the next screen. Select Adaptec AHA-2940U2W PCI Ultra2 SCSI Controller.
If Adaptec AHA-2940U2W PCI Ultra2 SCSI Controller is not on the list, you may be able to install the driver from the Adaptec EZ-SCSI Setup Diskette. Follow these steps:
Place the Adaptec EZ-SCSI Setup Diskette in the floppy disk drive. Double-click the Add New Hardware icon in Control Panel. Select No on the second screen of the wizard. Select SCSI controllers on the next screen. Click the Have Disk button, then click the Browse button.
Look in the \drivers\storage directory of the Windows 95 CD-ROM (or the root directory of the EZ-SCSI Setup Diskette) and select the model of your SCSI card.
How can I check the status of a resource (for example, IRQ, Memory, I/O)?
Click the Start button, point to Settings, then click Control Panel. Double-click the System icon. Click the Device Manager tab. Double-click the Computer icon. On the View Resources tab, click the option button for the type of resource you want to check. 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.
How do I use the Hardware Conflict Troubleshooter in Windows 95?
Click the Start button, then click Help. From the Contents tab, double-click Troubleshooting. Double-click If you have a hardware conflict. Follow the step-by-step instructions in the Windows Help window.

Common Error Messages

The following messages may appear at bootup:
Device connected, but not ready
The host received no answer when it requested data from an installed SCSI peripheral.
Run SCSISelect and set the Send Start Unit Command to Yes for the particular SCSI peripheral. Make sure the drive is set to spin up when the power is switched on. (See the documentation for the peripheral.)
Start unit request failed
The SCSI Card BIOS was unable to send a Start Unit Command to the peripheral.
Run SCSISelect and disable the Send Start Unit Command for the peripheral.

Time-out failure during.

An unexpected time-out occurred.
Verify the SCSI bus is properly terminated. Verify all cables are properly connected. Try disconnecting the SCSI peripheral cables from the SCSI card and then starting the computer. If the computer successfully restarts, one of the SCSI peripherals may be defective.
Using the SCSI Card 2940U2W and SCSI Peripherals
This section provides useful information on using the SCSI Card 2940U2W and your SCSI peripherals. For specific information, refer to the documentation that came with your SCSI peripheral.

Using SCSI Peripherals

Hard Disk Drives
Every SCSI hard disk drive must be physically low-level formatted, partitioned, and logically formatted before it can be used to store data. SCSI hard disks are physically low-level formatted at the factory and do not usually need to be formatted again. If you connect a new SCSI hard disk drive to your SCSI card, you must partition and logically format the drive. For DOS and Windows (3.x and 95) use the DOS Fdisk and Format commands (see your computer, DOS, and Windows documentation). For other operating systems, see your operating system documentation.
If you are booting from a SCSI hard disk drive, make sure the Hard Disk (or Drives) setting in your computers CMOS setup program is set to None or No Drives Installed, as is required for SCSI hard disk drives. See your computer documentation for details. 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.

Ultra2 Hard Disk Drives

We recommend keeping your Ultra2 hard disk drives separate from your non Ultra2 peripherals. Connecting a non Ultra2 hard disk drive to the Ultra2 connector on the SCSI Card 2940U2W causes the Ultra2 SCSI segment of the SCSI bus to drop down to Ultra SCSI performance levels (40 MBytes/sec). Do not connect your Ultra2 hard disk drives to connectors other than the Ultra2 connectors on the SCSI Card 2940U2W.
Ultra2 Internal Connector
Ultra2 External Connector
Figure 1. Ultra2 Internal and External Connectors
Internal Ultra2 SCSI peripherals come from the factory with termination disabled and cannot be changed. Proper termination is provided by the built-in terminator at the end of the Ultra2 internal SCSI cable provided in the kit.

Scanners

You will need to install the scanner manufacturers proprietary software drivers. See your scanners documentation for details.
SCSI Peripheral Display at Bootup
At bootup, each peripheral attached to the SCSI Card 2940U2W is identified by SCSI ID, name, the SCSI segment to which it is attached (Ultra2 or Fast/Ultra), and the mode (LVD-Ultra2 or SEUltra) in which it is running. For example, a message similar to the following appears on the screen at bootup: SCSI ID:0 Seagate ST39173LC Ultra2 LVD In this example, the peripheral is assigned SCSI ID 0; Seagate ST39173LC refers to the name of the peripheral; Ultra2 indicates that the peripheral is attached to the Ultra2 SCSI segment; LVD means that the peripheral is running in LVD-Ultra2 mode. LVD (Low Voltage Differential) is the enabling technology for Ultra2. If the peripheral is running in LVD-Ultra2 mode, this indicates that the peripherals maximum transfer rate is set at the Ultra2 SCSI performance level (80 MBytes/sec). SE (Single-Ended) is the enabling technology for Fast SCSI and Ultra SCSI. If the peripheral is running in SE-Ultra mode, this indicates that the peripherals maximum transfer rate is set at the Ultra SCSI performance level (40 MBytes/sec).
Note: If any peripheral is attached to the Ultra2 SCSI segment and is running at SE mode, one or more Wide Ultra/ Ultra peripherals is attached to the Ultra2 SCSI segment and is causing the Ultra2 SCSI segment to run at speeds up to 40 MBytes/sec instead of 80 MBytes/sec.
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) 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 peripherals. SCSI IDs can be reused as long as the ID is assigned to a peripheral on a different SCSI card (for example, each SCSI card can have a peripheral with SCSI ID 2).
If you have two or more SCSI cards, enable the BIOS on the boot SCSI card only; disable the BIOS on the remaining SCSI cards.
Connecting the LED Connector
(Optional feature) Most computers have an LED disk activity light on the front panel. 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, the LED on the front panel of the computer will light whenever there is activity on the SCSI bus (see Figure 2).
Note: If you are using non-SCSI disk drives (for example,

IDE), you may not want to connect your computers LED to the SCSI card, since the LED will no longer indicate nonSCSI disk activity.

Figure 2. Connecting the LED Cable to the LED Connector
Using SCSI and IDE (or EIDE) Peripherals
All Adaptec SCSI cards can coexist with another controller (IDE, EIDE, RLL, etc.) installed in the computer. If you have both an IDE hard disk drive and a SCSI hard disk drive, the IDE drive is typically the boot drive. In this case, disable the BIOS on the SCSI card (see Advanced Configuration Options on page 20). 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. You cannot connect an IDE peripheral to a SCSI card, or a SCSI peripheral to an IDE card (controller). Disable the BIOS on the SCSI card if no SCSI hard disk drives are installed (see Advanced Configuration Options on page 20).
Replacing a Non-Adaptec SCSI Card with an Adaptec SCSI Card
SCSI is standard, but how data is translated on to a hard disk drive is not. Each SCSI card manufacturer uses its own translation schemes for writing data to a disk. To use a hard disk drive previously connected to a non-Adaptec SCSI card, lowlevel format the drive after connecting to the Adaptec SCSI card. (See Using SCSI Disk Utilities on page 22.)
Caution: A low-level format destroys all data on the drive.
Be sure to back up your data before performing a low-level format.
Configuring the SCSI Card 2940U2W with SCSISelect
SCSISelect, included with the SCSI Card 2940U2W, enables you to change SCSI 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 1 lists the available and default settings for each SCSISelect option.
Note: The default settings are appropriate for most systems.
Run SCSISelect if you need to change or view current settings, or if you would like to run the SCSI disk utilities. See the descriptions of each option on page 17.
Table 1. SCSISelect Settings SCSISelect Option Basic Host Adapter Settings: Host Adapter SCSI ID SCSI Parity Checking Host Adapter SCSI Termination: Ultra2-LVD/SE Connector Fast/Ultra-SE Connector Automatic, Enabled, Disabled Automatic, Low ON/High ON, Low OFF/High OFF, Low OFF/High ON 0-15 0-7 Yes, No 80.0, 53.4, 40.0, 32.0, 26.8, 20.0, 16.0, 13.4, 10.0 Yes, No Yes, No Automatic Automatic 0-15 Enabled, Disabled 7 Enabled Available Settings Default Setting

Note: Set Initiate Wide Negotiation to No if you are using an 8-bit SCSI peripheral that hangs or exhibits other performance problems with 16-bit data transfer.
Send Start Unit CommandWhen set to Yes, sends the Start Unit Command to the SCSI peripheral at bootup. BIOS Multiple LUN SupportWhen set to Yes, the SCSI card BIOS provides boot support for a SCSI peripheral with multiple LUNs. Leave this setting set to No if your boot device does not have multiple LUNs. Include in BIOS ScanWhen set to Yes, the SCSI card BIOS includes the peripheral as part of its BIOS scan at bootup.
Advanced Configuration Options
Note: Do not change the Advanced Host Adapter Settings
unless absolutely necessary.
Plug-and-Play SCAM SupportWhen set to Enable, the SCSI card automatically assigns SCSI IDs to SCSI peripherals that support the SCAM protocol (see SCSI IDs on page 1). The default is Disable, but you can set it to Enable even if you have a non-SCAM peripheral. Reset SCSI Bus at IC InitializationWhen set to Enable, the SCSI card generates a SCSI bus reset during its power-on initialization and after a hard reset. Extended BIOS Translation for DOS Drives > 1 GByte When set to Enable, provides an extended translation scheme for SCSI hard disks with capacities greater than 1 GByte. This setting is necessary only for MS-DOS 5.0 or above; it is not required for other operating systems, such as NetWare or UNIX.The extended translation scheme supports disk drives as large as 8 GBytes. To partition a disk larger than 1 GByte controlled by the SCSI card BIOS, use the MS-DOS Fdisk command.
Caution: Back up your disk drives before changing the

translation scheme.

Host Adapter BIOS (Configuration Utility Reserves BIOS Space)Enables or disables the SCSI card BIOS.
Set to Enable if you boot from a SCSI disk drive connected to the SCSI card. Set to Disable if the peripherals on the SCSI bus (for example, CD-ROM drives) are controlled by software drivers and do not need the BIOS.
Support Removable Disks Under BIOS as Fixed Disks Determines which removable-media drives are supported by the SCSI card BIOS. Choices are as follows:
Boot OnlyOnly the removable-media drive designated as the boot device is treated as a hard disk drive. All DisksAll removable-media drives supported by the BIOS are treated as hard disk drives. Disabled No removable-media drives are treated as hard disk drives. Software drivers are required because the drives are not controlled by the BIOS.
