Hello!
Would anybody be interested in testing the TPM support I added to SeaBIOS. I unfortunately don't have a motherboard myself where I could try it. I have added the support to SeaBIOS for the TPM device model in Qemu. What you would need for trying it is a motherboard with a TPM 1.2 on it. The SeaBIOS TPM support should recognize it, initialize the TPM and allow the user to enter another SeaBIOS menu.
