Hey guys. I'm new here but I've been trolling for a bit looking up image problems etc. I'm hoping I can get some help with a problem I have ran into. So here's the thing. I have 4 laptops I need to distribute an image to. All of them are T-series thinkpads (30, 41, 42, 43). I created the image on the T30 which uses the "Advanced Configuration and Power Interface (ACPI) PC" driver. The T43 needs to use the "ACPI Uniprocessor PC" driver in order to install the TPM driver without hanging the system. I use Sysprep and then ghost the image, so I tried using the UpdateUPHAL = "ACPIAPIC_UP,%SystemDrive%\Sysprep\Hal\Hal.inf" parameter in the sysprep.ini file. Unfortunately, it keeps the original driver and does not update it to the "ACPI Uniprocessor PC" driver. I also tried making the image from the T43 and then going backwards to the T30. Again, the sysprep parameter UpdateUPHAL doesnt do anything and keeps the Uniprocessor driver, which the T30 cant even boot on. Any thoughts or help is greatly appreciated. I've been running through this problem for almost a week now. Thanks. [edit] if anyone knows how to change the acpi driver from vanilla to uniprocessor by some automatable way (cmd line, script, etc), that would solve this. dont even know if that is possible though..
