DRIVER SIGNING POLICY AND PLUG AND PLAY DEVICE DRIVERS
. .
. .
. .
If you intend to use any updated drivers, you must first verify that they have a valid signature. If
. .
they do not, the driver being installed will depend on:
. .
. .
. .
The driver signing policy you indicate in your answer file.
§
. .
. .
The availability of a compatible signed driver that ships with the operating system.
§
. .
. .
. .
DriverSigningPolicy
. .
. .
. .
Specifies how non-signed drivers are processed during unattended Setup. Signed drivers have gone
. .
through the Microsoft driver testing and signing process to ensure they are Windows 2000
. .
. .
compatible.
. .
. .
Block Setup does not install the non-signed device driver.
§
. .
. .
Warn Setup stops the installation and prompts the user for input before accepting the non-
. . §
. .
signed device driver.
. .
. .
Ignore Setup continues even if the driver is not signed.
§
. .
. .
. .
NOTE: Refer to Appendix C for examples of how to set these options in the UNATTEND.TXT.
. .
. .
. .
. .
. .
. .
IMPORTANT: Microsoft strongly advises against using DriverSigningPolicy = Ignore unless
. .
you have fully tested the device driver in your environment and are sure that it works properly.
. .
Using non-signed drivers increases the risk of device driver problems that can affect the
. .
. .
performance or stability of your computer.
. .
. .
. .
If you are using DriverSigningPolicy = Ignore and you attempt to install a newer, unsigned copy of
. .
a driver that is protected by Windows 2000, the policy level is automatically updated to Warn.
. .
