  • Page 105 Trusted Platform Module Trusted Platform Module (TPM) is a dedicated microprocessor designed to secure hardware by integrating cryptographic keys into devices. Software can use a TPM to authenticate hardware devices. Because each TPM chip has a unique and secret RSA key which is embedded during the manufacture of the TPM, it is capable of performing platform authentication operation.
  • Page 106 Figure 54. Installing the TPM Next steps Install the system board. Follow the procedure listed in After working inside your system. Initializing the TPM 1.2 for TXT users While booting your system, press F2 to enter System Setup. On the System Setup Main Menu screen, click System BIOS > System Security Settings.

Physical disks not visible to operating system Issue: One or both physical disks are not appearing for use by an operating system.
  • Page 123 Virtual disk not visible to operating system Issue: In RAID mode a virtual disk is not appearing for use by an operating system. Probable cause: Virtual disks will not be presented to the system if they are not native to the controller. Corrective action: Import the virtual disk using Hardware-Independent Imaging (HII).
  • Page 124 Probable cause: Working as designed, BIOS only allows booting from the first listed boot device (in this case, slot 0) per peripheral controller. This only occurs in legacy BIOS boot mode. Corrective action: Swap the drive in slot 1 to slot 0. CLI reports unsupported features Issue: Several commands, options, or other features listed by the Marvell CLI state that they are unsupported when run.
