On the GAMING PC

1

Power OFF the GAMING PC

• Perform a Flea Power Drain/Cold Boot

2

Move the USB cable

Power ON the GAMING PC

On the DMA PC

1

Flash the firmware

• Download the firmware .bin file from your order

Firmware is always delivered as a .bin file. If Windows renames it to an audio file like .mp3, rename the file extension to .bin or re-download the firmware.

• Use Kilmu's DMA Tool to flash firmware to the DMA card

If you experience issues flashing firmware, note: some DMA card manufacturers do not work well with Kilmu's DMA Tool. In this case, reach out to your DMA card's manufacturer and verify if you need to use their specific DMA flashing software/tool.

• click Select File
• choose your firmware .bin file
• from the drop-down, select your DMA card type (T-Rating):

  • for 35T cards: XC7A35T
  • for 75T cards: XC7A75T
  • for 100T cards: XC7A100T
• click Flash

Success! Your DMA card is flashed and ready to test.

2

Perform a speed test

• Using Kilmu's Speed Test option within the tool or using Lone's DMA test tool, perform a speed test on the DMA card

Success! You've validated the DMA card is installed, configured, and flashed correctly.

3

Move the USB cable

• Move the USB-C data cable to the DATA port on the DMA card

If the DMA card is not labeled, the DATA port is the port furthest from the PCB pins (top port).

• Perform a Flea Power Drain/Cold Boot on BOTH PCs

  • verify once more using a DMA test tool that the DMA card is connected and passes speed/throughput tests

On the GAMING PC

1

Adjust power options

• Press the Windows Key -> type power plan -> click edit power plan -> click Change advanced power settings -> set Hard Disk, Turn off hard disk, Setting (Minutes): 0

2

Install drivers

• If drivers are included in your order, download and install them.

Installing drivers using Windows Explorer

Some drivers do not have an executable to install them easily; we can use native Windows Explorer functionality to install.

Method to Install Drivers via Windows Exporer

1. If your driver is in an archive (.zip), extract it:

   • Right click on the .zip file and select Extract All...
2. Find the driver file:

   • Open the newly extracted folder.
   • Find the .inf file

     • If you are unsure about which file, in the Windows Explorer menu, click View and check the box for File name extensions.
   • Once you've located the .inf, right click on the file and select Install.

Right click on the .inf file and select Install

Installing drivers using command prompt

Some drivers do not have an executable to install them easily; we can use command prompt or Windows PowerShell to install via commands.

Methods to Force Install Drivers via CMD

1. Open Command Prompt as Administrator:

   • Press Win + S, type cmd, right-click Command Prompt, and select Run as administrator.
2. Using pnputil (Recommended):

   • Force Install/Update: pnputil /add-driver "C:\Path\To\Driver.inf" /install.
   • Force Override/Replace: If a driver is already present, use: pnputil /add-driver "C:\Path\To\Driver.inf" /install /force.
   • Install all drivers in a folder: pnputil /add-driver "C:\Path\To\Folder\*.inf" /subdirs /install.
3. Using drvload (For Windows Recovery/BMR):

   • To load a driver during boot-time (BMR), use: drvload C:\path\to\driver.inf.
4. Using PowerShell (Alternative to CMD):

   • To force install all .inf files in a folder:powershell

     $Drivers = Get-ChildItem "C:\mydrivers\" -Recurse -Filter "*.inf"
     ForEach ($Driver in $Drivers) {
         PNPUtil.exe /add-driver $Driver.FullName /install
     }
