BIOS-UEFI and CMOS Configuration Lab (Using TestOut LabSim PC Pro 7.0 ) Objective To allow students to study how the BIOS/UEFI operates and affects an operating system. Materials Student needs access to their LabSim TestOut PC Pro 7.0 software and the lab “ 3.8.11 BIOS/UEFI Security ”. On-campus students should have access to working desktops and/or laptops where they can reach the BIOS/UEFI (which might be password protected). Preparation These LabSim TestOut PC Pro 7.0 items should be viewed prior to this lab: 3.8.1 “BIOS/UEFI”; 3.8.2 “PC Boot Process”; 3.8.3 “BIOS/UEFI Facts”; 3.8.4 “Edit BIOS/UEFI Settings.” Instructions Working with BIOS/UEFI using the TestOut PC Pro 7.0 simulator: (1) Open LabSim TestOut PC Pro 7.0 by selecting any assignment on Canvas that links to TestOut . Click on the navigation menu in TestOut in the upper corner and select “ 3.8.11 Configure BIOS/UEFI Security ” . Start the LabSim, and the Windows 11 will appear in the simulation. ( NOTE: You do NOT complete the instructions listed in the LabSim lab until Step 8 in this assignment.) Note: Most images need to be cropped screenshots that focus on the information needed. Time-date is required in the screenshots to ensure the image is unique to you. (2) Your screenshots for this lab need your studentID visible. Open Powershell by right-clicking the Start icon in the center of the taskbar and choosing “Windows Terminal”. Type in cd Documents and hit enter; the path should now read C:\Users\Administrator\Documents. Type in mkdir yourstudentid (replace with your actual student ID) and hit enter, then type in dir (enter); a folder with your student ID as its name will be listed with the date and time of its creation. Move this window to the right side of your screen; your folder must appear in the screenshots of the Windows 11 Device Manager. Full- screen images and photos taken by a cell phone are not acceptable, for the image must be clear and legible without the need to zoom in. (3) Open Device Manager and expand the categories “Network adapters” and “Sound, video, and game controllers” so that the devices “Realtek 8169” and “Realtek S1220A” are visible in the list. Move the Device Manager over to the lower corner of your screen, near the current time and date, and confirm that your folder appears in the Powershell behind the Device Manager. Take a cropped screenshot of the Device Manager, your folder name, and the actual date/time visible in the taskbar in the image. Place this Device Manager image as Figure 1 in the Deliverables. (4) Choose Shutdown and, once it is off, unplug the TestOut PC in the simulator. This computer has two sticks of 8 GB RAM, totaling 16 GB. Open the case and remove one stick of the DDR4 memory modules from the computer, and set that stick of RAM aside until step 6. Plug the PC in. Restart the TestOut PC and while the screen is still black (it might say TestOut), click inside the screen and quickly hit the “F2” key on your keyboard. The BIOS screen should appear; it is a white and bluish-gray screen

and says “System Information” as one of the categories. If Windows 11 boots up, you will have to try again. Ask for help if you are unable to get to the BIOS/UEFI screen. (5) Choose “System Information ” in the BIOS/UEFI screen and scroll so that the Memory Information is visible. Note that the BIOS lists only 8 GB of RAM using one stick of DDR4 (because you removed the other memory module). Zoom in so that your actual Time/Date and the Memory Information will be legible in the screenshot. Then take a cropped screenshot showing the amount of RAM and the actual Time/Date. Place this BIOS image as Figure 2 in the Deliverables. (6) Turn off the LabSim computer and add the RAM back in, turn it on, then return to the BIOS/UEFI. Locate the Network Adapter in BIOS and disable the NIC and turn off the Audio as well. Choose Apply and Exit and allow the system to boot back to Windows 11. Open the Device Manager. Notice that you are unable to turn on the NIC or the Audio , for the categories “Network Adapters” and “Sound, video, and game controllers” are completely missing (if these categories are visible, then you need to return to BIOS and try again.) Open Powershell and type in cd Documents then type in dir to show your folder name. Place the Device Manager so that your folder name is visible behind it. Take a cropped screenshot of your modified Device Manager and your folder, and the current date/time stamp in the taskbar. Place this image as Figure 3 in the Deliverables . (7) Return to the BIOS/UEFI and restore the settings of the NIC and audio. Move to “Boot Sequence” in the BIOS/UEFI and notice how the screen changes when you choose “UEFI” as opposed to “Legacy” as the “Boot List Option.” While set to “Legacy,” modify the boot sequence by making the CD/DVD first, the Internal HDD (Hard drive) second, and removing the other three items from the list (de-select them). Take a cropped screenshot showing your modified Boot Sequence and the current time/date in your actual taskbar. Place this image as Figure 4 in the Deliverables . (8) Save the BIOS and allow the computer to boot. After confirming you have the required images, choose “Start Over.” Now complete the lab “ 3.8.11 Configure BIOS/UEFI Security” . When you hit “Score Lab,” take a cropped screenshot that shows your score, the Task Summary, and your current time/date in your actual taskbar. Note: you probably completed this lab earlier in the term, so this additional effort should only take a few minutes. Place this image as Figure 5 in the Deliverables . (9) For on-campus students : access computers on the campus and attempt to reach the BIOS by rebooting the system and pressing the correct key (this tends to vary depending on the model). Are the BIOS routines protected by a password? Why is the use of a BIOS password a common practice? If you are able to access the BIOS, then make similar changes (that is, disable the NIC, the Sound, change the boot routine, etc.) and note the effects. Be sure to return the BIOS to its former state. Do not leave a password on the BIOS of a real computer. For on-campus students: Discuss what options you could change on actual computers and their effects. Discuss how you would acquire screenshots of BIOS screens for reports.

Deliverables Answer any lab questions and place any images in this section. Include any relevant research you found to support your answers. ( Tip! Be sure to check with your instructor for anything else that needs to be included in this section.) Each screenshot should take one-half page to a full page; screenshots must be legible and complete. Use Ctrl-Enter to place each screenshot with its title on its own page, if desired. Reminder: use LabSim TestOut PC Pro 7.0 “3.8.11 Configure BIOS/UEFI Security” to acquire your screenshots. The time and date need to be visible in the screenshots.
