BIOS update using DOS shell

    Important note
    You assume full liability for a failed BIOS update! If problems occur during or after the BIOS update, we CANNOT repair your device under warranty!
    If you want to perform a BIOS update, you will need a bootable DOS system for some older TUXEDO models. If your downloaded BIOS folder does not have a .nsh file, but instead mainly has .exe and .bat files, you will need to perform the flash operation using a DOS system.
    This guide should not be a problem for experienced users, however: only perform a BIOS update if you are absolutely sure what you are doing. Experience with handling CMD or terminals is more than just desired!

    You can also access the BIOS of your TUXEDO Book by restarting the device with the following command
    sudo systemctl reboot --firmware-setup

    Step 1: Create a bootable USB stick with DOS shell

    1. Unplug all unused storage devices such as USB sticks, USB hard drives, etc. to prevent data loss!

    2. Download the image for the bootable USB stick here.

    3. Open a terminal in the newly created directory and insert an empty USB stick. Already existing data will be overwritten!

    4. Find out which letter was assigned to the USB stick. Please execute this command:

    sudo fdisk -l

    Displays all disks and partitions. Which one is your USB stick can also be attached to the size, for example. In most cases the USB stick is also listed in last place. In this example, the notebook has only one hard disk installed and otherwise only the USB stick is plugged in. This results in /dev/sdb as the right choice!
    Make sure you are in the correct directory!


    5. Enter the following:

    gunzip -c bootstick_50M.img.gz | sudo dd of=/dev/sdx


    Whereby the name of your USB stick is entered at /dev/sdx.

    Caution: If you enter a wrong name here you can irrevocably destroy your operating system! In most cases it's not /dev/sda!

    Step 2: BIOS flashing

    Please make sure that your notebook is connected to the mains, otherwise no BIOS update/flash will be executed!

    1. Deactivate UEFI in your device's BIOS (usually via F2) before proceeding! This is done in a submenu, there either via »UEFI Settings« or »Security Settings«. Here you should be able to disable UEFI or switch to legacy. If this possibility does not exist, you should find two almost identical entries for your USB stick in the boot menu. Once with »UEFI:« before and once without. You must select the entry without »UEFI:«. The boot menu is accessible via F7 or F10 immediately after switching on the notebook.

    2. Execute the commands specified for the respective BIOS (see Update_Legacy.txt) and wait briefly. The notebook then switches itself off automatically and possibly on again. If it does not shut itself off, please press the power button manually until it goes off. If it switches on again or you have to switch it on again after 10 seconds of waiting, you have to boot again from the USB stick via F7 or F10!

    3. Then execute the next command mentioned. The notebook then switches itself off or you would have to switch it off.

    4. When you have completed all update/commands, please disconnect your device from the power supply for 5 minutes (and pull out the battery if this is easily possible from outside). Then you can plug it back in and turn it on.
