ASRock TPM 2.0 Module on ASRock H81M-HDS and Secur

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hardware: ASRock H81M-HDS Motherboard with ASRock TPM 2.0 Module
OS: Windows 10 , UEFI Boot , GPT HDD.

BIOS 2.20
TPM 2.0 - BIOS detected module but CURRENT STATUS TURNED OFF.
Windows 10 System Information status - Secure Boot Enabled.

BIOS 2.30A
TPM 2.0 - Module detected and Enabled.
Windows 10 System Information status - Secure Boot Unsupported.

The problem are:
1. BIOS v2.30A Secure Boot feature is not working.
2. BIOS v2.20 does not support TPM 2.0

Therefore I can see BIOS v2.30A is the only version that is able to detect TPM 2.0 module, but the BIOS Secure Boot feature is not working.

Please kindly help to fix the problem. Thanks.

	Hi, I also have the same problem, what would you recommend now or what are you currently using? 1. TMP I 2.30a I without secure boot 2. without TPM I 2.30 I secure boot So variant 1 or 2? Or did you spontaneously find another solution?

	TPM 2.0 modules won't work with this board. Only TPM 1.2 is possible. I got a TPM 1.2 module from Authikey, and it works.
