Windows 2000/XP introduced a new feature called Driver Signing, in which drivers are certified by the Microsoft Logo testing program and a digital signature added to inform the operating system of a successful certification.
As WAVECOM drivers are only used in a small number of computers, they are not submitted to Microsoft for certification. As a result, during driver installation, a dialog box will be displayed to inform the user that the driver is not signed.
This message does not indicate that a problem exists with the driver. It is a purely informational message to notify the user that the driver does not contain a digital signature. To complete the driver installation, users should select the Continue Anyway button.
