Solved unknown devices in Windows Server 2008 Standard SP1 (x64) OS on Dell Precision T7500 workstation (Rev: 1.0)

After installing Windows Server 2008 Standard Service Pack 1 (x64) Operating System (OS) on the Dell Precision T7500 workstation, there are various unknown devices in the Control Panel -> System -> Hardware -> Device Manager as shown below:

1. 3D video controller
-> Using Nvidia Quadro FX580 video card and Nvidia Tesla C1060 GPU card. We have added Nvidia Tesla C1060 GPU card (with 240 of Streaming Processor Cores and 4 GDDR3 memory) in the Dell Precision T7500 workstation. If you did not added the Nvidia Tesla C1060 GPU card, you will only see the Nvidia Quadro FX580 (512 MB) video card. Installing the device drivers using nVidia driver version 8.16.11.9100, A01.

2. Ethernet Controller
-> Using Broadcom NetXtreme 57xx Gigabit Controller. Installing the device drivers using Broadcom 57XX Gigabit Integrated Controller version 14.1.0, A05.

3. SM Bus Controller
-> Using Intel (R) ICH10 Family SMBus Controller - 3A30. Installing the device drivers using the "Chipset -> Intel driver version 9.1.0.1007, A23 (R205428) or higher version" from Dell.

4. System Interrupt Controller
-> Using Intel (R) 5520/5500/x58 I/O Hub GPIO and Scratch Pad Registers - 3422. Installing the device drivers using the "Chipset -> Intel driver version 9.1.0.1007, A23 (R205428) or higher version" from Dell.

5. System Interrupt Controller
-> Using Intel (R) 5520/5500/x58 I/O Hub GPIO and Scratch Pad Registers - 3422. Installing the device drivers using the "Chipset -> Intel driver version 9.1.0.1007, A23 (R205428) or higher version" from Dell.

6. System Interrupt Controller
-> Using Intel (R) 5520/5500/x58 I/O Hub Control Status and RAS Registers - 3423. Installing the device drivers using the "Chipset -> Intel driver version 9.1.0.1007, A23 (R205428) or higher version" from Dell.

7. System Interrupt Controller
-> Using Intel (R) 5520/5500/x58 I/O Hub Control Status and RAS Registers - 3423. Installing the device drivers using the "Chipset -> Intel driver version 9.1.0.1007, A23 (R205428) or higher version" from Dell.

8. System Interrupt Controller
-> Using Intel (R) 5520/5500/x58 I/O Hub System Management Registers - 342E. Installing the device drivers using the "Chipset -> Intel driver version 9.1.0.1007, A23 (R205428) or higher version" from Dell.

9. System Interrupt Controller
-> Using Intel (R) 5520/5500/x58 I/O Hub System Management Registers - 342E. Installing the device drivers using the "Chipset -> Intel driver version 9.1.0.1007, A23 (R205428) or higher version" from Dell.
