Troubleshooting

If you encounter issues, follow this troubleshooting checklist:

• DMA Card Not Detected

  • Reseat the DMA card in the PCIe slot.

  • Try a different PCIe slot.

  • Use a different, known-good data cable.

  • Check Device Manager or lsusb for device presence.

• VMM INIT FAILED or Similar Errors

  • Perform a full shutdown (cold boot) of the Target PC, wait 5 seconds, and power back on.

  • Review BIOS settings:

    • Disable all virtualization features (VT-d, SVM, IOMMU).

    • Set PCIe slot to Gen1.

    • Disable Kernel DMA Protection, Secure Boot, and NX/XD Bit.

  • Ensure the correct driver is installed on the Radar PC.

  • Use the official DMA test tool to check hardware status.

• Slow Speeds or Unstable Operation

  • Try setting the PCIe slot to Gen2 or Gen3 if supported and stable.

  • Use a different USB port or cable.

  • Update motherboard BIOS to the latest version.

  • Ensure both systems are set to High Performance power plans.

• Frequent Disconnects or Data Errors

  • Check for power supply issues on both systems.

  • Avoid using USB hubs or extension cables.

  • Ensure cables are not damaged or loose.

• Persistent Issues

  • Reinstall drivers and DMA software.

  • Test the DMA card on a different system to rule out hardware faults.
