Getroffen producten en herstel

Product Affected Versions Updated Versions Link to Update

To determine the TPM firmware version used on your system:
  1. In System BIOS Settings > System Security, if TPM Information shows as Type: 1.2 NTC and TPM Firmware shows 7.4.0.0 an update is required.
  1. In Windows, run “tpm.msc”. TPM Manufacturer Information shows Manufacturer Name as Nuvoton. If Manufacturer Version shows as 7.4.0.0 and Specification Version as 1.2, an update is required.
  1. In Linux, run the following commands, which displays the following output.
Install tpm-tools package using distro specific tools. Then run from the command line:
# tpm_version

This will output something like this:
TPM 1.2 Version Info:
Chip Version: 1.2.5.81
Spec Level: 2
Errata Revision: 3
TPM Vendor ID: NTC
Vendor Specific data: 0201
TPM Version: 01010000
Manufacturer Info: 57454300

To check the firmware version, run the following from the command line:
# grep "Firmware version" /sys/class/tpm/tpm0/caps

This will output something like this:
Firmware version: 5.81

BIOS updates require a reboot for installation, and scheduling a maintenance window is recommended to perform the BIOS update.
