### 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     "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 the driver where the arrow is pointing at says WinUSB ("Version number") and press Replace Driver.

### -> Make sure that it says that the installation was successful and it looks like the after picture.    6.  Go into the OCD folder.
