			TPM Management - tpm_setownable

NAME
     tpm_setownable - change whether the TPM allows tpm_takeownership operations

SYNOPSIS
     tpm_setownable [OPTION]

DESCRIPTION
     tpm_setownable  reports  the status of the TPM's flags regarding if the TPM
     can be owned.  This is the default behavior and  also  accessible	via  the
     --status  option.	Requesting a report of this status prompts for the owner
     password.	The --allow option sets the system's TPM to allow tpm_takeowner-
     ship operations (via the TPM_SetOwnerInstall API).  This operation requires
     physical presence.  The --prevent option (via the TPM_SetOwnerInstall  API)
     prevents  the TPM from accepting tpm_takeownership operations.  This opera-
     tion  requires  physical  presence.   These  operations   are   persistent.
     tpm_takeownership requires the tpm be enabled.
