This connector supports
Trusted Platform Module (TPM)
system, which can securely
store keys, digital certificates,
passwords, and data. A TPM
system also helps enhance
network security, protects
digital identities, and ensures
platform integrity.
This motherboard supports
CASE OPEN detection feature
that detects if the chassis cover
has been removed. This feature
requires a chassis with chassis
intrusion detection design.
