• The security chip function is only enabled for models MG32M/B-F and MG33L/B-F.
• The security chip does not guarantee complete protection of data or hardware.
Always exercise appropriate caution when managing and handling important data.
• In addition to the security chip function, we recommend configuring supervisor and
user passwords to the BIOS setup utility.
• When performing computer recovery, reinstalling the operating system, or using a
separately sold operating system, initialize the security chip before enabling it.
Refer to "Before sending your computer for repair" for the procedure to initialize the

Enable the security chip
You can reset security chip feature settings by setting [Change TPM State] to [Clear].
Therefore, we recommend you set up a supervisor password/user password before
you use security chip features so that a higher level of security can prevent a third
party from resetting security chip feature settings.
