# How to Flash a 35T DMA Card

**For Squirrel 35T / Captain 35T DMA**

**1. Make sure the DMA is properly inserted in a PCIe slot on the Gaming-PC.**

**2. Make sure that the Gaming-PC is powered on.**

**3. Plug the DMA USB-Cable into the "Update" port or "JTAG" on the DMA Card and the  other end into the 2nd-PC.**

**4. Go into the Flash Tools folder and open "zadig-2.8.exe".**\
**5. In Zadig open "Options" - Tick "List All Devices" and select**\
&#x20;   **"Quad RS232-HS (Interface 0)"**

**-> It is important that you select "Interface 0"!**

**-> If you do not see the "Quad RS232-HS" options and instead see a "FTDI SuperSpeed-FIFO Bridge" it most likely means that you are plugged in the Data port and not the Update Port.**

**-> Make sure that it says that the installation was successful and it looks like the after picture.**
