Security Chip Function

Outline
• The security chip function is valid on models MG33M/B-K and MG36L/B-K only.
• 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, reset, 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
security chip.
