Parameters
| Name | Explanation |
| lpVendorID | The retrieved vendor number |
| lpszVendorName | The retrieved vendor name In C++Builder, Visual C++, and Delphi. this is a string terminating with Null. In Visual Basic, this is a string of specified size. |
| lpVendorNameLen | The length (in digits) of the retrieved vendor name. |
| lpDeviceID | The retrieved product number. |
Return Value
Returns the True (nonzero) if successful, otherwise returns False (0).
Explanation
The PK3QueryHostBridgeID function retrieves the northbridge vendor number, name, and product number from the PC's motherboard.
The PK3QueryHostBridgeID function is disabled if the PK3Initialize function has not been executed.
The Motherboard Northbridge identifier (contained in the PcID as retrieved by the PK3QueryPcID function) will be a number made of the "vendor number (4 digits)" + "product number (4 digits)" . This number is then converted to a string. In most cases, the northbridge cannot be detached from the motherboard which is not hte case with a CPU's video card or network card.
