Type: Automated Test

Overview

This test validates that the BIOS on this platform meets the Windows Vista and Windows Server 2008 BitLocker Drive Encryption feature requirements.

Details

This test is a test of pre-operating system functionality.
 
This test is executed in the pre-operating system environment and not on the Microsoft Windows operating systems in order to get access to the TCG BIOS interface. The Tcgtest.exe binary is responsible for setting up the test result files and scheduling the Tcgpreos.exe binary in the boot configuration data.
 
This test will run after a restart. This execution phase might not be visible. As a result, the Boot Manager will display the list of all possible operating systems to start. Proceed back to the operating system in which the test was started, and then call Tcgtest.exe again. The first run of Tcgtest.exe will generate the log with the file name TCGTestPre.xml; the second run of Tcgtest.exe (after the reboot) will generate the log with the file name TCGTestPost.xml. To see which test assertion results are in TCGTestPre.xml and which are in TCGTestPost.xml, see "Test Tool Assertions."
 
NOTE: BitLocker Drive Encryption has to be turned off or at least cannot be bound to the TPM. Otherwise, the start of the operating system will fail until the system is restarted after the test has been performed.

Run Time: 4 minutes
Log File: TCGTestPre.xml and TCGTestPost.xml (see "Full Description and Theory of Operation")
System Restart Required: Yes

Running BitLocker Drive Encryption BIOS Interface Logo Test

Execute the Job from the DTM framework.
 
As an alternative, run this test without DTM by following these steps:
  1. Make sure that Tcgpreos.exe is in the same directory as Tcgtest.exe. 
  2. To start the test and initialize the test environment, type the following in the command line: 
    Tcgtest.exe 
  3. Upon return to the command line prompt, manually restart the system; test results are determined in the  pre-OS phase of this restart. 
  4. After the system restarts, you can see test results by typing the following in the command line: 
    Tcgtest.exe
