TPM Config
The parameter is displayed in Advanced as TPM Config or TPM/TCM Config based on the server model or BIOS version.
This section describes how to configure TPM related parameters on the TPM Config screen. Figure 4-37 or Figure 4-38 shows the TPM Config screen. Table 4-27 or Table 4-28 describes the parameters on the screen.
The TCG2 Configuration screen varies according to the server, BIOS version, or TPM.
