Hi jrk7352 I have the same issue as you, in that I've updated the HAL fine and I've used the steps listed previously to install the NSC TPM driver, but it still shows up as unknown device. If I update the driver via the hardware update wizard and point it to the nsctpmdd.inf it installs fine. This is due to the updated HAL (ACPI Multiprocessor). Did you get anywhere nearer resolving the issue??
