1 Introduction 1 Introduction 1.1 Summary The BIOS is the firmware of a computer. Regular BIOS updates help improve the security and stability of the computer system. To find out what you should know before and during a BIOS update, see section 1.5. Preliminary steps for a BIOS update are documented in section 2. Various ways to start the BIOS update process and update the BIOS are described in section 3. 1.2 Motivation Software updates and the associated updates of application programs and the operating system bring about improvements and bug fixes. To keep a computer system up-to-date, you should therefore install updates regularly. In addition to the operating system and the application programs, a computer also includes software that tests the existing hardware components at system startup. It loads and runs the operating system. This particular software is the Basic Input Output System (BIOS), or on more recent computers the Unified Extensible Firmware Interface (UEFI). It is located in a memory chip that is part of the motherboard of a computer. Like any other software, the BIOS or the UEFI (hereafter referred to simply as the BIOS) is subject to a constant improvement process. A new BIOS version can improve system stability and reliability, or enable the use of new hardware components. The improvements and enhancements of a new BIOS version will be available after updating the BIOS on each IPC. This document describes how to update the BIOS of the IPC. The possibilities presented can also be applied to other SIMATIC IPC types and SIMATIC Field PGs. 1.3 BIOS tasks The task of the BIOS is to initialize the components of a computer at system startup. These include the CPU, memory and input and output devices. Depending on its characteristics, a BIOS can contain additional functions, e.g. for secure data processing with the aid of a TPM chip. Some Intel processors also provide comprehensive remote access to the computer using Intel Active Management Technology (iamt). The prerequisite for this function is a connection to the Internet and the connection to a supply voltage. From the point of view of the BIOS, this function is anchored in the Management Engine (ME). The Intel Management Engine is usually updated along with the BIOS. 1.4 Components used This application example was created with these hardware and software components: Entry ID: 109757305, V1.1, 08/2018 4

Create a hard drive backup Carry out a backup according to the application example "Simple backup and restore of SIMATIC IPCs". Note or save the BIOS settings before updating the BIOS After completing a BIOS update, it is recommended to set the BIOS settings to their default values. Simply open BIOS setup for the corresponding function. Figure 1-1 1 2 Entry ID: 109757305, V1.1, 08/2018 5

1 Introduction Then adapt syour individual BIOS settings to your individual requirements so that the system functions as usual after the BIOS update. Refer to application and system program notes for BIOS updates Note Please note the information on the BIOS update, which is contained as a text file (*.txt) in the respective ZIP archive. In addition, it may be necessary to disable certain application programs for the duration of the update process. If you are using one or more of the following programs, follow the instructions provided. Table 1-2: Notes on individual application and system programs Program Bitlocker CPU 1507S Note If you are using Bitlocker, make sure that before updating the BIOS data Bitlocker is disabled. Alternatively, back up the recovery keys of the drives with Bitlocker enabled on an external drive. Validity: SIMATIC Software Controller CPU 1507S SIMATIC Failsafe SW Ctrl CPU 1507S F If you have installed the software controller CPU 1507S on your IPC, restarting the IPC does not update the BIOS. In this case, start the IPC without the software controller or follow the update process in section 3.1 or in section 3.3. Further information on updating the BIOS when using a software CPU can be found in the manual "SIMATIC Industrial PC BIOS Description", see link collection in section 4.3, link \3\. Do not interrupt the update process CAUTION An incomplete update process can render the system unable to boot. Therefore, do not interrupt the update process. If, despite all precautionary measures, the update process has been interrupted and the IPC does not start, contact a Siemens repair center in your area. Note Siemens offers support for SIMATIC IPCs worldwide. You will find the contact details of repair centers in your area in the contact database, see link collection in section 4.3, link \4\. Do not interrupt the update process even if there there seems to be a standstill. Some BIOS updates take longer than usual because, for example, in addition to the normal BIOS update, the software of the Intel Management Engine is also being updated. It may happen at approximately 50% progress that the BIOS update seems to stop for several minutes. If this situation occurs, then be sure not to interrupt the update process. Do not under any circumstances interrupt the power supply. Do not try to restart the computer. After a few minutes, the update process is finished and a corresponding message is displayed. Entry ID: 109757305, V1.1, 08/2018 6

1 Introduction Stabilize mains voltage with a UPS If large voltage fluctuations or short-term failures can occur in the power supply network of the SIMATIC IPC, use an upstream uninterruptible power supply (UPS). This allows you to bridge power failures that would cause the BIOS update to abort. Running BIOS updates twice If a BIOS update additionally contains an update of the Intel Management Engine, but does not update it automatically, then the update must be done twice manually. During the first run, the BIOS is updated as usual and the computer is restarted. At this point, however, still lacks the update of the Intel Management Engine and the following note appears while booting: "Error Intel Management Engine Version not up-to-date, please run BIOS update. Press ESC/F2/F12 to continue". Restart the BIOS update process in this situation. The second run updates the Intel Management Engine and the computer restarts normally. Do not downgrade the BIOS Downgrading the BIOS to an earlier version is not recommended as it can negatively impact stability and system security. Should it nevertheless be necessary to operate the SIMATIC IPC with an earlier BIOS version, further intermediate steps and updates may be necessary. Details can be found in the documents of the respective BIOS version and in the notes of the previous BIOS updates. Entry ID: 109757305, V1.1, 08/2018 7

This graphic should help with orientation and finding your way quickly in this document.

2.2 Determining the existing BIOS version and the IPC type To determine if a BIOS update is necessary, the currently used BIOS version must be determined. This section describes several ways in which you can determine the currently used BIOS version of your SIMATIC IPC. If you already know the existing BIOS version of your SIMATIC IPC, you can skip this section. Determining the existing BIOS version using Windows system information (msinfo32.exe). If neither DiagBase nor DiagMonitor is installed on your SIMATIC IPC, then determine the BIOS version using the Windows system information: 1. Open the Windows system information. Run the program "msinfo32.exe". 2. Determine the BIOS version of your IPC in the "System Overview" node by the value of the "BIOS Version/Date". Figure 2-3 3. This example is a SIMATIC IPC427D with BIOS version V17.02.06. Entry ID: 109757305, V1.1, 08/2018 10

Determining the existing BIOS version without operating system If access to an operating system is not possible on the SIMATIC IPC, then determine the BIOS version via the BIOS setup of the IPC: 1. Connect a keyboard to the SIMATIC IPC. Switch on the SIMATIC IPC. The SIMATIC IPC initializes the integrated and externally connected components. A message appears for a few seconds to display the boot options. 2. When the message appears, press the button to display "boot options". This is usually one of the following keys: "F2", "Esc" or "Del". Figure 2-4 Note If this text note does not appear, then the time may be too short for the screen to display it. In this case, watch the NUM-Lock LED on your keyboard when switching on. As soon as it lights up briefly, press the Esc, F2 or Del key. Then the BIOS selection menu appears. 3. In the BIOS selection menu, use the arrow keys on your keyboard to navigate to the "SCU" selection. This will take you to the BIOS setup menu. Entry ID: 109757305, V1.1, 08/2018 11

Figure 2-5 4. In the BIOS setup menu you will find the version name of the used BIOS version under the menu item "Main". Figure 2-6 Determining the existing BIOS version with SIMATIC IPC DiagBase or DiagMonitor If you use a SIMATIC IPC with the preinstalled SIMATIC IPC DiagBase program package, then determine the installed BIOS version by following the steps below. Note The SIMATIC IPC DiagBase software can be downloaded from the following Link. Entry ID: 109757305, V1.1, 08/2018 12

1. Open the DiagBase application window by double-clicking on the AlarmManager icon ( ) in the info area of the Windows desktop of the IPC. 2.

2.3 Transferring the BIOS data to a USB stick To prepare for the subsequent update process, the BIOS data to be updated must be transferred to a USB stick. Note This is necessary with all the following current devices: IPC2x7E IPC4x7D IPC4x7E IPC6x7D IPC8x7D FPG M4 FPG M5 ITP1000. The USB stick requires the following properties for the BIOS update process. The USB stick is formatted in the FAT or FAT32 file system. The BIOS data is located in the "BIOS" directory. Checking the file system If you already have a bootable USB stick from section 2.4.1 then this is already formatted in the correct file system. Steps to review and customize the file system 1. Connect the USB stick to your computer. Make sure the USB flash drive is formatted in the FAT or FAT32 file system. 2. Start Windows Explorer. Right-click to open the shortcut menu of the drive that represents the USB stick. 3. Select the menu item "Properties..." with the left mouse button. The properties of the drive are displayed.

3 Starting the BIOS update process 3 Starting the BIOS update process This section describes different ways to start the BIOS update process of a SIMATIC IPC. Before starting the update, read the version history and note the prerequisites for the BIOS update. 3.1 Starting the update process via the BIOS selection menu Some SIMATIC IPCs contain a function for updating the BIOS in the BIOS Setup menu. You can find out if your SIMATIC IPC supports this in the manual of your device type. Note This is the preferred BIOS update option for all current devices: IPC2x7E IPC4x7D IPC4x7E IPC6x7D IPC8x7D FPG M4 FPG M5 ITP1000 The prerequisite for the steps in this chapter is that you have a USB stick prepared with the new BIOS data as described in section 2.3. In addition, it is strongly advised to carry out a backup according to the application example "Simple backup and restore of SIMATIC IPCs". Proceed as follows: 1. Connect a keyboard and the prepared USB stick to the SIMATIC IPC. Switch it on. The IPC initializes the keyboard and the USB stick. A message appears for a few seconds to display the boot options. When this message appears, press the button to display the boot options. This is usually one of the following keys: "F2", "Esc" or "Del". Figure 3-1 Entry ID: 109757305, V1.1, 08/2018 35

3 Starting the BIOS update process Note If this text note does not appear, then the time may be too short for the screen to display it. In this case, watch the NUM-Lock LED on your keyboard when switching on. As soon as it lights up briefly, press the Esc, F2 or Del key. Then the BIOS selection menu appears. 2. In the BIOS selection menu, use the arrow keys on your keyboard to navigate to the "BIOS Update" selection and start the update process with the Enter key. Figure 3-2 3. The IPC starts the BIOS update process. 4. From here follow the steps in section 3.2. Entry ID: 109757305, V1.1, 08/2018 36

3 Starting the BIOS update process 3.2 Replacing the old BIOS version During the BIOS update process, the BIOS data of the IPC is replaced by newer BIOS data. CAUTION Danger due to incomplete update process If the BIOS update process has started, aborting the process may result in incomplete transfer of the new BIOS data. As a result, the IPC cannot be restarted, and the memory chip of the BIOS or the mainboard of the IPC must be replaced in a repair center. Do not interrupt the update process and wait for the update to finish. Make sure that no sudden power failures have any influence on the operating status of the IPC, e.g. by using a UPS. Proceed as follows to replace the BIOS version: 1. The BIOS update process starts with the message "Firmware Update: [...]" and a countdown. Figure 3-3 2. While the countdown is running, press on the Y button 1 on the keyboard connected to the IPC, or wait until the countdown has completed. 3. A note about the use of Bitlocker and the question about whether you want to start the update now appear. Confirm the query with the Y key. Figure 3-4 4. An additional text with license conditions appears. Read the license conditions and confirm them with the Y key. 1 Note that the default keyboard layout is active at system startup. The keys for Y and Z are swapped in comparison to the German keyboard layout. If you are using a keyboard with a German keyboard layout, press the Z key instead.

3 Starting the BIOS update process 5. After confirming the license terms, the update process begins. Do not interrupt the update process and wait until the progress bar reaches 100%. Figure 3-5 6. After the BIOS has been successfully updated, the message "Program finished" will appear. Figure 3-6 7. Press any key to restart the system. The BIOS update is complete. Entry ID: 109757305, V1.1, 08/2018 38

3 Starting the BIOS update process 3.3 Starting the update process using a bootable USB stick If on your SIMATIC IPC no SIMATIC IPC DiagBase can be used no SIMATIC IPC DiagMonitor can be used or the boot menu of your SIMATIC IPC does not contain the "BIOS Update" function, Then start the update process with the help of a bootable USB stick. Note This is the preferred way for the following devices: IPC2x7D IPC4x7C IPC6x7C IPC8x7C or older. The IPC first starts the operating system FreeDOS from the USB stick. Subsequently, the BIOS version is updated. The prerequisite for this is that you have a USB stick prepared with the BIOS data to be updated. Note If, when trying to start the IPC from the USB stick, no USB stick is detected, or the IPC only starts from the built-in data medium, then this may be due to the fact that in the settings of the BIOS setup the option to start a USB device is not active, or the IPC may not be started in legacy mode and only in UEFI mode. In this case, change the corresponding settings in the BIOS setup of your IPC for the duration of the BIOS update. The specific menu items can be found in the respective manual of your IPC model. A general description of the BIOS setup can be found in section 3 of the "SIMATIC Industrial PC BIOS Description" operating manual, see the links in section 4.3, link \9\. On some IPC models, you can access the Boot Manager menu to select the possible boot options by pressing the F12 key during startup. For the newer SIMATIC IPCs, open the Boot Manager menu from the BIOS selection menu. The following table describes the necessary steps as an example on a SIMATIC IPC427D. 1. Connect a keyboard and the prepared USB stick to the SIMATIC IPC and switch it on. The IPC initializes the keyboard and the USB stick. A message appears for a few seconds to display the boot options. Entry ID: 109757305, V1.1, 08/2018 39

3 Starting the BIOS update process Figure 3-7 Note 2. When the message appears, press the button to display the boot options. This is usually one of the following keys: "F2", "Esc" or "Del". If this text note does not appear, then the time may be too short for the screen to display it. In this case, watch the NUM-Lock LED on your keyboard when switching on. As soon as it lights up briefly, press the Esc, F2 or Del key! Then the BIOS selection menu appears. 3. In the BIOS selection menu, use the arrow keys on your keyboard to navigate to the "Boot Manager" selection and confirm your selection with the Enter key. Figure 3-8 4. The Boot Manager menu displays the available drives of the IPC. Entry ID: 109757305, V1.1, 08/2018 40

3 Starting the BIOS update process Figure 3-9 5. The bootable USB stick has the name "FK310-128M Mobile Disk" in this example. Use the arrow keys to navigate to the entry of your USB stick and confirm your selection with the Enter key. The IPC then boots from the USB drive. 6. As soon as the boot process is connected, the command prompt of the operating system of the USB stick appears. Figure 3-10 7. Change to the "BIOS" directory and start the BIOS update process by opening the "Update.bat" file. 8. The IPC starts the BIOS update process. 9. From here follow the steps in section 3.2 in case the BIOS update process was not carried out automatically. Note The BIOS update process is completed when the command line appears again. Entry ID: 109757305, V1.1, 08/2018 41

3 Starting the BIOS update process 3.4 Update Process for IPC 3x7E The requirement is that the preparations from section 2.4 are completed. 3.4.1 Starting the update process 1. Start the IPC from the bootable stick. This will get you into the DOS system. 2. Enter the command "dir" and confirm with the enter key. Thus, you can check if all necessary files are on the stick. Figure 3-11 If all necessary files are on the stick or are listed, then you can start the BIOS update process: 3. Type in "go" and confirm with the Enter key. BIOS will now start the auto refresh. Figure 3-12 If the BIOS update is successful, the IPC restarts automatically after the BIOS Auto Refresh is completed. Note Do not interrupt the power supply during the BIOS update. Otherwise, the BIOS update may fail. At the end of the update process it makes sense to set the "boot mode" and "video mode" according to the operating system as follows: Windows 7: Set "boot mode" and "video mode" to "legacy" in the "boot" tab in the BIOS setup menu. Windows 10: Set "boot mode" and "video mode" to "UEFI" in the "boot" tab in the BIOS setup menu. Entry ID: 109757305, V1.1, 08/2018 42

3 Starting the BIOS update process 3.5 Update process for IPC 547G 3.5.1 Bios update using a bootable USB DOS stick 1. Restart the IPC so that the IPC boots from the bootable USB DOS stick. 2. Type the "DOSFLASH.BAT" command to start the automatic BIOS update process. Figure 3-13 3. Confirm that you want to update the BIOS with "y". Figure 3-14 Note Do not forget to change the boot order back to its default settings at the end of the BIOS update. Entry ID: 109757305, V1.1, 08/2018 43
