How to: Install a SCSI controller card.
Solution:
Observe ESD considerations, and install the legacy SCSI controller card.
WARNING: Electrical shock hazard! Make sure the power is turned off and the external power cables have been disconnected before removing the computer cover.
CAUTION 1: This task should be performed by a qualified computer technician.
CAUTION 2: Please observe steps to reduce the potential damage to computer components from electrostatic discharge.
NOTE 1: The following instructions are to install a SCSI controller for use with secondary hard drives, and other non-bootable devices. Configuring a SCSI controller to use a primary bootable system device or hard drive, may require a full reinstallation of Windows 95 on the primary SCSI hard drive or bootable device.
NOTE 2: Refer to the SCSI controller adapter card manual to determine what types of hardware resources (direct memory access (DMA), interrupt request (IRQ), and input/output address (I/O addresses) are needed by the SCSI controller and the specific value range for each resource that can be set on the adapter card using jumpers or switches.
NOTE 3: SCSI controllers can be installed a computer with other active hard drive controller types such as ESDI, IDE, and EIDE. To boot from a hard drive on the SCSI controller in a system with other installed hard drive types, you will need change your hard drive boot sequence to SCSI first in the BIOS setup as shown in the example below. Otherwise, the computer will boot from the non-SCSI hard drives first. If your computer's BIOS does not allow you to select the hard drive boot sequence, the computer will only boot from a SCSI hard drive if no non-SCSI are installed in the computer.

NOTE 4: Some SCSI controller adapter card also include a floppy drive controller. If you are not going to use the floppy drive controller on the SCSI controller adapter card, you must disable the floppy drive controller before installing the adapter card. Refer to the adapter card manual or contact next-level support for further instructions.
1) Click the 'Start' button to display the 'Start' menu.
2) Select 'Settings' and select 'Control Panel'. (The 'Control Panel' window appears.)
'Control Panel' window
3) Double-click the 'System' icon. (The 'System Properties' dialog box appears.)
4) Click the 'Device Manager' tab, and select the 'View devices by type' radio button. (The system devices are displayed.)
Device Manager
5) Select the 'Computer' icon, and click 'Properties'.
Select Computer and click Properties
6) Click 'Properties'. (The 'Computer Properties' dialog box appears.)
Computer Properties
7) Select the 'Interrupt request (IRQ)' radio button. (The dialog box lists the devices with interrupt assignments and radio button name.
8) Record which interrupts are not assigned.
9) Select the 'Direct memory access (DMA)' radio button. (The dialog box lists the devices with DMA assignments and radio button name.)
10) Record which DMAs are not assigned.
11) Select the 'Input/output (I/O)' radio button. (The dialog box lists the devices with memory addresses and radio button name.)
12) Click the 'Reserve Resources' tab, and do the following:
NOTE: If you attempt to reserve a resource currently assigned to a device, a 'Resource Conflict Warning' message will appear stating if you reserve a resource in use that a resource conflict may occur. If possible, choose a different value to reserve.
a) Select the 'Interrupt request (IRQ)' radio button, and click 'Add...'. (The 'Edit Resource Settings' dialog box appears.)
b) Enter a IRQ value to be used by the SCSI controller card in the 'Value' list box, and click 'OK'.
'Edit Interrupt Request' dialog box
NOTE: If more than one IRQ is needed for the SCSI controller card, repeat step b).
c) Select the 'Direct Memory Access (DMA)' radio button in the 'Value' list box , and click 'Add...'. (The 'Edit Resource Settings' dialog box appears.)
d) Enter a DMA value to be used by the SCSI controller card in the 'Value' box, and click 'OK'.
'Edit Direct Memory Access' dialog box
NOTE: If more than one DMA is needed for the SCSI controller card, repeat step 12)d).
e) Select the 'Input/output (I/O)' radio button, and click 'Add...'. (The 'Edit Resource Settings' dialog box appears.)
f) Enter a I/O address to be used by the SCSI controller card in the 'Value' box, and click 'OK'.
'Edit Input/Output Range' dialog box
NOTE: If more than one I/O Range address is needed for the SCSI controller card, repeat step 12)f).
g) Select the 'Memory' radio button, and click 'Add...'. (The 'Edit Resource Settings' dialog box appears.)
NOTE: 'Memory' is also referred to as the 'base memory address'.
h) Enter a memory address to be used by the SCSI controller card in the 'Value box, and click 'OK'.
NOTE: If more than one memory address is needed for the SCSI controller card, repeat step 12)h).
i) Click 'OK' to close the 'Computer Properties dialog box.
13) Shut down Windows 95, and turn off the computer.
14) Disconnect the external power cord from computer.
15) Remove the computer cover.
16) Set the jumpers on the SCSI controller card to match the device resources reserved in steps 12a) through 12i).
NOTE: Refer to the SCSI controller card manual for proper jumper settings.
17) Determine the expansion slot type for the SCSI controller card.
18) Align the SCSI controller card with an empty slot matching the card, and insert the card into the slot.
Aligning a card with a expansion slot
CAUTION: Keep the card vertical while inserting it into an expansion, and be careful not to bend the SCSI adapter card. Bending the SCSI adapter card board can damage the circuitry.
19) Connect the ribbon data cable to the connector on SCSI hard drive controller card and to the large connector on the rear of the hard drives (red or blue side to Pin1).
NOTE 1: Linked SCSI devices sharing the same controller form a 'SCSI chain' SCSI controllers require that the chain is terminated at both ends. The SCSI controller card itself forms one termination, and the other termination must be added to the last device connected to the controller cable. Refer to the manual for the SCSI devices for instructions concerning terminating the 'SCSI chain'.
NOTE 2: SCSI controllers require that each device on the 'SCSI chain' have a unique SCSI ID number. The SCSI ID numbers are commonly set by jumpers or switches on the devices themselves. Refer to the manual for the SCSI devices for assigning SCSI ID numbers to a device.
20) Reconnect the external computer power cord, and turn on the computer. (Allow Windows 95 to start normally.)
NOTE: Windows 95 may auto-detect the new SCSI controller card and will prompt you to add the SCSI controller card as new hardware. If so, skips step 21) through 24).
21) Open the 'Add New Hardware' icon ('Add new hardware wizard' dialog box appears), and click 'Next'.
'Add New Hardware Wizard' dialog box
22) Select the 'No' radio button and click 'Next'.
Select 'No' radio button and click 'Next'
23) Select 'SCSI controllers' from the 'Hardware types' list box, and click 'Next'.
24) Select manufacturer and model of the SCSI controller card from the 'Manufacturers' and 'Models' list boxes respectively, and do one of the following:
a) To install the drivers for the SCSI controller card supplied by the manufacturer, click 'Have Disk...', and follow the manufacturer's instructions.
Click 'Have Disk...'
NOTE: It is recommended that you install the SCSI controller card with drivers supplied by the manufacturer. Refer to the SCSI controller card manual for detailed installation steps.
b) To install the drivers for the SCSI controller card supplied with the Windows 95 CD-ROM do the following:
'Select manufacturer and model'
NOTE: To install the SCSI controller card with drivers from the Windows 95 CD-ROM, you will need to have the Windows 95 CD-ROM in your CD-ROM drive or have access to the Windows 95 CD-ROM.
25) Shut down Windows 95, and turn off the computer.
26) Replace the computer cover, and turn on the computer.
