Optiplex 3010, TPM activation?

I've updated to the lastest BIOS (A27), but don't see the TPM settings in the BIOS. Strange thing is that I can run cctk.exe --tpmsecurity=enabled and it shows that it's enabled. When I run tpm.msc from Windows 7 it says there isn't a supported TPM 1.2 chip. 

Since it looks like I won't get TPM working is there a list of Optiplex systems that support TPM 1.2?
