Steam Installation Tutorial
Add box repositories
sudo bash -c 'if wget -q https://ryanfortner.github.io/box86-debs/box86.list -O /etc/apt/sources.list.d/box86.list; then if wget -qO- https://ryanfortner.github.io/box86-debs/KEY.gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/box86-debs-archive-keyring.gpg; then echo "box86 repository and key added successfully."; else echo "Error adding box86 key."; fi; else echo "Error downloading box86 repository list."; fi; if wget -q https://ryanfortner.github.io/box64-debs/box64.list -O /etc/apt/sources.list.d/box64.list; then if wget -qO- https://ryanfortner.github.io/box64-debs/KEY.gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/box64-debs-archive-keyring.gpg; then echo "box64 repository and key added successfully."; else echo "Error adding box64 key."; fi; else echo "Error downloading box64 repository list."; fi'
Installing Dependencies
First we need to install some dependencies that are required by Steam. Use the following lines:
Find your DRK version here: box86/docs/COMPILE.md at master · ptitSeb/box86 · GitHub
sudo dpkg --add-architecture armhf && sudo apt update
Fixing missing packages:
sudo apt install binutils box86-rk3588 box64-rk3588 libfaudio0 libc6:armhf libsdl2-2.0-0:armhf libsdl2-image-2.0-0:armhf libsdl2-mixer-2.0-0:armhf libsdl2-ttf-2.0-0:armhf libopenal1:armhf libpng16-16t64:armhf libfontconfig1:armhf libxcomposite1:armhf libbz2-1.0:armhf libxtst6:armhf libsm6:armhf libice6:armhf libgl1:armhf libxinerama1:armhf libxdamage1:armhf libncurses6:armhf libgl1-mesa-dri:armhf curl:armhf mesa-vulkan-drivers
if on ubuntu:
sudo add-apt-repository -y ppa:kisak/kisak-mesa
if on debian: sudo nano /etc/apt/sources.list
deb http://deb.debian.org/debian bookworm-backports main contrib non-free non-free-firmware
sudo apt update ; sudo apt install -t bookworm-backports mesa-vulkan-drivers mesa-utils
Install Steam
First we need to configure the environment for Steam. Use the following lines to add two environment variables to your Linux environment:
mkdir -p ~/steam && mkdir -p ~/steam/tmp && cd ~/steam/tmp && wget https://cdn.cloudflare.steamstatic.com/client/installer/steam.deb && ar x steam.deb && tar xf data.tar.xz && rm ./*.tar.xz ./steam.deb && mv ./usr/* ../ && cd ../ && rm -rf ./tmp/ && bash -c 'cat <<EOF > steam && chmod +x steam && sudo mv steam /usr/local/bin/
#!/bin/bash
export STEAMOS=1
export STEAM_RUNTIME=1
export DBUS_FATAL_WARNINGS=0
export PAN_MESA_DEBUG=gofaster,gl3
box64 ~/steam/bin/steam \$@
EOF'
Now just sudo reboot
Type steam on terminal
Installation is now finished EnJoy!
Final Steps we need for ChromiumOS (FydeOS/openFyde):
Ctrl alt t - Open Crosh via Chromium Browser
vsh termina
lxc config set penguin security.privileged true
lxc restart penguin
Now on penguin terminal do sudo su to be on Root! not just sudo and type:
sudo su
tail -n 1 /etc/binfmt.d/box86.conf > /proc/sys/fs/binfmt_misc/register
tail -n 1 /etc/binfmt.d/box64.conf > /proc/sys/fs/binfmt_misc/register
exit #leave root
steam
For all games set settings to -force-opengl and maybe install proton experimental like always.. after installing steam perform a steam restart bugs may follow and retry is key.
All credits for this magical addition goes to @andrebraga !! 
Alternatively if you can use the NicoD Script (Optional might not work of ChromiumOS):
