# Setting up the hardware

Here is a diagram of how you connect all of the pieces (click to full size). Build everything as shown in the diagram and insert the flexible cable of HDMI bridge into the narrow white connector on the Raspberry Pi (the closest one to the USB).

**Raspberry Pi 4 note**: since it uses one USB-C female connector to giving power and keyboard/mouse/drive emulation you also need to make a special Y-cable to split DATA and POWER lines of USB-C (see [reasons](https://github.com/pikvm/docs/issues/11)). You can make it from two suitable connecting cables, or solder from scratch. Be sure to check the circuit diagram, otherwise you may damage your devices. Pinout specific used connectors you can easily find on request "USB pinout" in Google. Please note that if you will make a cable based on the two different manufecturers, the colors of the wires may not match those shown in the picture. Use a multimeter to make sure the connections are correct.

# Building OS
|

Pi-KVM OS is based on Arch Linux ARM and contains all required packages and configs to work. To build the OS you will need any Linux machine with a fresh version of Docker (we recommand >= 1:19) with privileged mode (for fdisk and some other commands, check Makefiles if you don't trust us :).

2. Determine the target hardware configuration (platform). Choose the board (`BOARD=rpi4` for Raspberry Pi 4 or `BOARD=zerow`, `BOARD=rpi2`, `BOARD=rpi3` for other options). Next, choose the platform: `PLATFORM=v2-hdmi` for RPi4 or ZeroW; `PLATFORM=v0-hdmi` for RPi 2 or 3. Other options are for legacy or specialized Pi-KVM boards (WIP).
|
||||
|
||||
3. Create config file `config.mk` for the target system. You must specify the path to the SD card on your local computer (this will be used to format and install the system) and the version of your Raspberry Pi and platform. You can change other parameters as you wish. Please note: if your password contains the # character, you must escape it using a backslash like `ROOT_PASSWD = pass\#word`.

If none of this works, try connecting the DP cable first, boot into the BIOS, disable CSM and shutdown (do not restart) your PC. Boot into the BIOS and enable CSM then shutdown your PC. Then connect the HDMI and turn it on again.
