ABSTRACT:
The inventive system provides the correct device driver name about a currently installed device to a software program. The system works with the Microsoft.RTM. Windows.RTM. plug and play capable operating system. The system uses the system registry, has device information about every device which has ever been installed on the system to provide the driver name. The SYSTEM.INI is not updated by the plug and play subsystem, such that if a previously installed device is reinstalled, the SYSTEM.INI file is not updated, and hence it will hold invalid information. The inventive system substitutes a reference to a proxy in place of the invalid information in the SYSTEM.INI file. Thus, when the program queries the system file for information about the device driver, it instead activates the proxy, which in turn supplies a reference to the correct device driver by using the configuration manager program to scan the system registry to locate the correct driver.
