Delphi: Getting the Bus Reported Device

Hey there, readers!

Welcome to our exhaustive guide on "delphi get bus reported device." This article is a treasure trove of knowledge for anyone looking to delve into the intricacies of this topic. We’ll cover everything from the basics to advanced techniques, ensuring that you leave with a thorough understanding.

Understanding the Concept of Bus Reported Device

What is a Bus Reported Device?

In Delphi, a bus reported device is a system component that resides on a PCI or PCI Express bus and communicates with the operating system through the bus driver. It enables the operating system to interact with specific devices, such as expansion boards or peripheral devices.

Bus Reported Device vs. System Device

It’s important to distinguish between bus reported devices and system devices. System devices are built into the computer’s motherboard and are essential for its operation, such as the BIOS or memory controller. Bus reported devices, on the other hand, are optional add-ons that provide additional functionality to the computer.

Getting the Bus Reported Device Information

Using the System Information Tool

Steps to Retrieve Bus Reported Device Information

1. Launch the System Information tool (msinfo32.exe) from the Run dialog box.
2. Expand the "Components" node in the left-hand pane.
3. Select "PCI" or "PCI Express."
4. The right-hand pane will display a list of all bus reported devices on the system.

Using the Delphi GetBusReportedDevice Function

Syntax and Parameters

function GetBusReportedDevice(BusReportedDevice: Pointer): Boolean;

• BusReportedDevice: A pointer to a TBusReportedDevice object that will receive the information about the bus reported device.

Usage

procedure TForm1.FormCreate(Sender: TObject);
begin
  var
    BusReportedDevice: TBusReportedDevice;
  if GetBusReportedDevice(BusReportedDevice) then
  begin
    ShowMessage(Format('Vendor: %d, Device: %d', [BusReportedDevice.VendorID, BusReportedDevice.DeviceID]));
  end;
end;

Retrieving Specific Device Information

Using the TBusReportedDevice Object

Once you have the TBusReportedDevice object, you can access its properties to obtain specific information about the device. Some important properties include:

• VendorID: The vendor identifier of the device manufacturer.
• DeviceID: The device identifier of the specific device model.
• PhysLocation: The physical location of the device on the PCI or PCI Express bus.

Listing Bus Reported Devices

Using the GetBusReportedDevices Function

function GetBusReportedDevices(BusType: Byte): Pointer;

• BusType: The type of bus to scan for devices. Can be PCI or PCIExpress.

Enumerating Device Resources

Using the EnumBusReportedResources Function

function EnumBusReportedResources(BusReportedDevice: Pointer; Enumerator: TFEnumBusReportedResources): Boolean;

• BusReportedDevice: A pointer to the bus reported device to enumerate resources for.
• Enumerator: A function that iterates over the resources of the device.
