TPM on GX620

I recently bought a GX620 comes with a TPM. Can anyone tell me who is the manufacturer and model of the TPM? I would like to do some experiments with the TPM on linux but without knowing the manufacturer and model, I won't know what drivers I need. Thanks in advance!

    Thanks for the reply :)
     
    Correct me if I'm wrong but I think the embassy security center is built upon the TPM device driver for Windows environment and Dell/STMicroelectronics does not provide the TPM device driver for linux?

    Well, now, isn't one of the "features" of Linux the ability (or necessity) of writing your own drivers?  Would it be possible you could find what you need on a Linux user forum?

    Yes and no. Yes because there are indeed works going on in developing linux drivers for TPM. Drivers for TPMs from Infineon, NSC and Atmel have been integrated into the linux kernel core (v2.6.12 abv). No because I have not come across anyone working on drivers for STM yet.

    How about it we want to access TPM perior to OS being loaded? Is there any interface available at that time?

    should be disabled in bios as the default.  Activate through bios.

    Most bios should provide you with some really limited access to the TPM, such as enabling/disabling/reset the TPM. As for taking ownership etc, not that I know of.

    I tried on D610 with Broadcom TPM. I enabled and activated the TPM in BIOS, and then tried to use BIOS int 1Ah (AH=BBh) by writting assembly code, but it didn't detect the presence of the TPM! Anybody has done this before?
