Wyse 5070 Displays Fatal Error on Boot When Updating to Dell ThinOS Version 9.x

Affected Platforms:

• Wyse 5070

Affected Operating Systems:

• Dell ThinOS 9.x

When updating the Wyse 5070 to ThinOS 9.x, if the BIOS is a revision earlier than 1.3.1, a fatal error occurs upon boot.

Upgrade the Wyse 5070 BIOS to 1.3.1 or later before updating to ThinOS 9.x.

Check for a Trusted Platform Module (TPM) or Platform Trust Technology (PTT) option in the BIOS. This is located within the Security category.

If there is a TPM or PTT option in the BIOS, then there is no further action required.

If there is not a TPM or PTT option in the BIOS, update the BIOS to the latest revision and then update ThinOS. ThinOS 1.3.1 or later enables the TPM or PTT.

If the operating system was updated before the BIOS, clear the TPM or PTT.

To clear the TPM or PTT:

1. Boot the affected unit into the BIOS by tapping F2 during boot.
2. From the BIOS, click to expand Security and then click TPM 2.0 Security.
   
   Note: TPM 2.0 Security may be titled differently in Wyse devices that are purchased for use in China or Russia.
3. Click Unlock.
   
4. Populate a password if prompted, and then click Clear.
   
5. When prompted to clear all keys, click Yes.
   
6. Click Exit.
