I´m trying to install drivers for the TPM chip in my IBM Thinkpad T42 unattended. The problem is that the TPM chip is reported as an unknown device and the only way of installing the drivers (by hand) is to "force" them in with "Have disk". Windows complains about that the driver might not work, but it does. Is there a way to make this unattended? I´m using the latest driver from IBM, so that should not be a problem (other than the unknow device thing, wich seems to be a common problem ). Cheers! EDIT: Attached the driver tpm_driver.7z
