HP 260 G1 DM - Bootfehler nach Update

Last modified by Tobias Wintrich on 2026/07/22 09:49

A customer has reported boot errors after updating to a RangeeOS version newer than 13.00 Build 165 on their HP 260 G1 DM.

The errors can manifest in different ways. In most cases, the boot screen freezes after a few minutes and the desktop does not start.

The cause is a stricter check of the default behavior of the Intel IOMMU. This now checks for correct functionality. If this check fails, some components cannot be initialized correctly. There is presumably a BIOS bug here that causes the IOMMU to not be used correctly. However, as long as you do not intend to virtualize anything on the hardware, this is not a major issue and the function can be disabled.

Booting the device in the error state (one-time)

If a device is already in the error state, it must be booted once via a manual change in order to then permanently disable the option via the Kommbox. Proceed as follows:

If you have disabled the boot menu via configuration, the only option at this point is to reinstall the device:
RangeeOS - Installation from a USB stick

  1. Stop the boot menu by repeatedly pressing the Down arrow key.
  2. Select the Boot entry and press the e key on your keyboard.
  3. Navigate to the end of the line that begins with "linux $bzImage......" (the END key takes you immediately to the end of the line).
  4. Add this parameter here:
    intel_iommu=off
  5. Then start the OS with CTRL+X and configure the option in the Kommbox.

Setting the option via the Kommbox

Once you have rebooted the device, you can configure this option in the Kommbox:

Under System -> Bootloader, set the option intel_iommu to off (the Expert Mode must have been enabled in the top right for this).

You can also safely distribute this option to all devices in your TCMS.
