The module is compatible with embedded software for TCG firmware enhancement and hardware accelerators for cryptographic operations, including SHA 1 and SHA 256, and a random number generator (RNG).

It supports Intel TXT, Windows, and Chromebook authentication standards.

5. Setup and Installation

Before proceeding with installation, please review the following important notices:

• Motherboard Manual Check: Always consult your motherboard's manual to confirm that it supports TPM 2.0 technology and has the correct 10-pin SPI header.
• BIOS Update: Some motherboards may require a BIOS update to the latest version to enable the TPM option in the BIOS settings.
• Security Technologies: It is recommended to remove or disable any other existing security technologies (e.g., older TPM modules, specific software-based security features) from your computer before installing this module to prevent conflicts.

Installation Steps:

1. Power Off System: Ensure your computer is completely powered off and disconnected from the power source.
2. Open Computer Case: Carefully open your computer case to access the motherboard.
3. Locate TPM Header: Identify the 10-pin SPI TPM header on your motherboard. Refer to your motherboard manual for its exact location.
4. Insert TPM Module: Align the ASHATA TPM 2.0 module with the 10-pin header. Gently press the module into the header until it is securely seated. Ensure the orientation is correct to avoid damage.
5. Close Case: Once the module is installed, close your computer case.
6. Power On System: Reconnect the power and turn on your computer.

6. Operating Instructions

After physical installation, the TPM module typically needs to be enabled and configured within your system's BIOS/UEFI settings.

1. Access BIOS/UEFI: During system startup, repeatedly press the designated key (commonly Del, F2, F10, or F12) to enter the BIOS/UEFI setup utility. The specific key varies by motherboard manufacturer.
2. Locate TPM Settings: Navigate through the BIOS/UEFI menus to find settings related to "Security," "Trusted Computing," or "Advanced." Look for options like "TPM State," "Intel Platform Trust Technology (PTT)," or "AMD fTPM."
3. Enable TPM: Set the TPM state to "Enabled" or "Active." You may also need to enable "Secure Boot" or other related security features depending on your system's requirements.
4. Save and Exit: Save the changes to the BIOS/UEFI settings and exit. Your system will restart.
5. Verify in Operating System: Once the operating system loads, you can verify the TPM status.
   • Windows: Press Win + R, type tpm.msc, and press Enter. The TPM Management console will display the status of the TPM.
   • Linux: Use commands like dmesg | grep -i tpm or check the /dev/tpm0 device.

Once enabled, the TPM module will function automatically with compatible operating system features and applications that utilize trusted computing capabilities.

7. Maintenance

The ASHATA TPM 2.0 Module is a passive component and requires minimal maintenance. Follow these guidelines for optimal performance and longevity:

• Physical Care: Keep the module free from dust and moisture. Ensure it is securely seated in its header.
• Firmware Updates: TPM firmware updates are typically handled through motherboard BIOS/UEFI updates. Always refer to your motherboard manufacturer's website for the latest BIOS versions and instructions.
• System Environment: Operate your computer in a clean, dry, and temperature-controlled environment to prevent damage to internal components, including the TPM module.

8. Troubleshooting

If you encounter issues with your ASHATA TPM 2.0 Module, consider the following troubleshooting steps:

• TPM Not Detected:
  • Ensure the module is correctly and firmly seated in the motherboard's TPM header.
  • Verify that your motherboard supports TPM 2.0 and has the correct 10-pin SPI header.
  • Check your motherboard's BIOS/UEFI settings to ensure TPM is enabled.
  • Update your motherboard's BIOS/UEFI to the latest version.
• TPM Errors in OS:
  • Ensure all necessary drivers (usually part of OS or chipset drivers) are installed.
  • If migrating from an older TPM, ensure the old TPM was cleared or disabled before installing the new one.
  • Check for conflicting security software or settings.
• System Instability After Installation:
  • Remove the TPM module and check if the system stabilizes. If it does, re-verify compatibility and installation steps.
  • Ensure the module is not damaged.

For persistent issues, consult your motherboard's support documentation or contact ASHATA customer support.
