Setting BIOS attributes using WinRM

You can set BIOS attributes using the SetBIOSAttributes method. The procedure is explained below using a task of enabling the Trusted Platform Module (TPM) as an example. For detailed information, see Managing Dell client systems remotely using Dell Command | Monitor 10.2 .
  • NOTE: Make sure the TPM option is cleared in the BIOS before following the procedure to enable the TPM.

To set the BIOS attributes using WinRM commands:

  1. Get the selector set by enumerating the DCIM_BIOSService class. Run: 
    winrm e wsman/DCIM_BIOSService?__cimnamespace=root/dcim/sysman -auth:basic -r:https://<system IP or system name>:<Port Number
                                    (5985/5986)> -username:<user name> -password:<password> -skipCAcheck -skipCNcheck -encoding:utf-8 -returnType:epr
    • NOTE: The selector set values (SystemName=<system name from DCIM_BIOSService class>winrm i SetBIOSAttributes wsman/DCIM_BIOSService?SystemName=dt: +SystemCreationClassName=DCIM_ComputerSystem+Name=DCIM:BiosService+CreationClassName=DCIM_BIOSService+) will be used for set operation in this example.
  2. Set the BIOS password on the system if not set already using the following command: winrm i SetBIOSAttributes http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/DCIM_BIOSService?__cimnamespace=root/dcim/sysman+Name=DCIM:BiosService+SystemCreationClassName=DCIM_ComputerSystem+SystemName=<system name from DCIM_BIOSService class>+CreationClassName=DCIM_BIOSService -r:https://<system IP or system name>:5986 -u:<user name> -password:<password> -auth:basic -skipCAcheck -skipCNcheck -encoding:utf-8 @{AttributeName="AdminPwd";AttributeValue="<Password>"}
  3. Enable TPM security by running the following command: winrm i SetBIOSAttributes "http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/DCIM_BIOSService?__cimnamespace=root/dcim/sysman+Name=DCIM:BiosService+SystemCreationClassName=DCIM_ComputerSystem+SystemName=<system name from DCIM_BIOSService class>+CreationClassName=DCIM_BIOSService -r:https://<system IP or system name>:5986 -u:<user name> -password:<password> -auth:basic -skipCAcheck -skipCNcheck -encoding:utf-8 @{AttributeName="Trusted Platform Module";AttributeValue="1";AuthorizationToken="<Admin password>"}
  4. Restart the system.
  5. Activate the TPM using the following command: winrm i SetBIOSAttributes "http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/DCIM_BIOSService?__cimnamespace=root/dcim/sysman+Name=DCIM:BiosService+SystemCreationClassName=DCIM_ComputerSystem+SystemName=<system name from DCIM_BIOSService class>+CreationClassName=DCIM_BIOSService -r:https://<system IP or system name>:5986 -u:<user name> -password:<password> -auth:basic -skipCAcheck -skipCNcheck -encoding:utf-8 @{AttributeName=("Trusted Platform Module Activation");AttributeValue=("2");AuthorizationToken="<Admin password>"}
