How to: Replace an IDE hard drive controller card.
Solution:
Observe ESD considerations, and install the legacy IDE hard drive 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: Skip steps 1) through 12) if you are installing a new IDE hard drive controller and cannot boot your computer from a hard drive.
NOTE 2: IDE hard drive controllers commonly use interrupt request (IRQ) value of '14' for the primary IDE controller and '15' for the secondary IDE controller. Use steps 1) through 12) to determine if there are any devices using IRQ '14' or '15'. Refer to the IDE hard drive controller adapter card manual to determine which IRQ values can be set using jumpers on the card.
NOTE 3: If there is an IDE hard drive controller is embedded on the motherboard, you may need to disable the IDE controller on the motherboard before the new controller adapter card can be installed. You can add the new IDE hard drive controller as a secondary IDE controller with the IDE hard drive controller on the motherboard configured as the primary IDE controller. For further instructions on how to configure multiple IDE controllers, contact next-level support or refer to the technical manuals for your computer, and hard drive controllers.
NOTE 4: Some IDE hard drive controller adapter cards also include a floppy drive controller. If you are not going to use the floppy drive controller on the IDE hard drive controller adapter card, 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. (The system devices are displayed.)

5) Select the 'Computer' icon, and click 'Properties'.
Select Computer and click properties
6) Click 'Properties'. (The 'Computer Properties' dialog box appears.)

8) Record the interrupts that 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.)
DMA
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.)
IRQ
12) If IRQ '14' or '15' is currently being used, do the following:
a) Click the 'Reserve Resources' tab.
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.
b) Select the 'Interrupt request (IRQ)' radio button, and click 'Add...'. (The 'Edit Resource Settings' dialog box appears.)
'Edit Interrupt Request' dialog box
c) Enter '14' in the 'Value' list box, and click 'OK'.
d) Enter '15' in the 'Value' list box, and click 'OK'.
e) Click 'OK' to close the 'Computer Properties' dialog box.
f) Click 'OK' to close the 'System Properties' dialog box.
13) Shut down Windows 95, and turn off the computer.
14) Disconnect the external power cord from the computer.
15) Remove the computer cover.
16) Set the jumpers on the card to match the device resources reserved in steps 12)a) through 12)f).
NOTE: Refer to the adapter card manual for proper jumper settings.
17) Determine the expansion slot type for the IDE hard drive controller card.
18) Locate the existing IDE hard drive controller card by tracing the ribbon cable connected to the hard drives back to the controller.
19) If the IDE hard drive controller is an adapter card, do the following:
a) Unplug the cables connected to the IDE hard drive controller adapter card.
b) Remove the screw securing the IDE hard drive controller card to the computer.
c) Lift the adapter card from the expansion slot with both hands.
CAUTION: Be careful not snag any cables or scratch components when lifting the IDE hard drive controller card from the computer..
20) If the IDE hard drive controller is embedded on the motherboard, do the following:
a) Unplug the cables connected to the IDE hard drive controller.
b) Disable the IDE hard drive controller using hardware jumper(s).
NOTE: Refer to the computers user manual for instructions on how to disable onboard floppy controller.
21) Align the IDE controller card with an empty slot matching the card, and insert the card into the slot.
CAUTION: Keep the card vertical while inserting it into an expansion, and be careful not to bend the IDE hard drive controller card. Bending the IDE hard drive controller card can damage the circuitry.
22) Connect the ribbon data cable to the connector on the IDE hard drive controller card and to the large connector on the rear of the hard drives (red or blue side to Pin1).
23) Replace the computer cover.
24) Reconnect the external power cord, and turn on the computer. (Allow Windows 95 to load normally.)
NOTE: Windows 95 will auto-detect the new IDE hard drive controller card and auto configure system drivers for the controller.
