Quick Start Guide

Get your BC-250 up and running with this fast-track checklist.

Requirements First

Before starting, ensure you have everything from the Prerequisites page.

Setup Checklist

Step 1: BIOS Flash (Critical)

Must Do First

The modded BIOS unlocks essential features like dynamic VRAM allocation and proper fan control. Skip this and you'll have a bad time.

  1. Download modded BIOS from bc250-bios repository
  2. Format USB stick as FAT32
  3. Rename BIOS file to robin5.00
  4. Copy to USB root directory
  5. Use included flashing utility
  6. CRITICAL: Clear CMOS after flashing (remove battery 30 seconds)

Difficulty: Easy

Step 2: BIOS Configuration

Boot into BIOS (Del key during startup) and configure:

  • VRAM Split: 512MB (Dynamic)
  • Fan Control: Full Speed (for testing) or Customize
  • IOMMU: Disabled (MUST disable - IOMMU is broken)
  • Boot Mode: UEFI

Step 3: Install Linux

Recommended: Fedora or Bazzite

Fedora 42/43 and Bazzite have the best out-of-box support. Other distros work but need more manual setup.

Fedora Installation:

  1. Download Fedora 42 or 43 Workstation
  2. Boot installer in "Basic Graphics Mode" (enables nomodeset automatically)
  3. Complete installation normally
  4. Reboot

Difficulty: Easy

Step 4: Install Drivers & Governor

Run the automated setup script:

# For Fedora 42/43
# Mesa 25.1+ is included in Fedora 43 repos - no additional setup needed
sudo dnf update

# Install governor from COPR
sudo dnf copr enable @exotic-soc/oberon-governor
sudo dnf install oberon-governor
sudo systemctl enable --now oberon-governor.service

# For Bazzite
curl -s https://raw.githubusercontent.com/vietsman/bc250-documentation/refs/heads/main/oberon-setup.sh | sudo sh

This installs:

  • Mesa 25.1+ drivers (already in Fedora 43+ / Bazzite)
  • Oberon GPU governor (required for performance)
  • Sensor drivers (lm-sensors package)
  • System optimizations

Difficulty: Easy

Step 5: Remove nomodeset

Critical Step

After drivers are installed, you MUST remove nomodeset or the GPU won't work properly.

sudo nano /etc/default/grub

# Find this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset"

# Change to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"

# Save and update GRUB
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

# Reboot
sudo reboot

Step 6: Verify Installation

Check that everything works:

# Check Mesa version (should be 25.1+)
glxinfo | grep "OpenGL version"

# Check GPU detected
vulkaninfo | grep deviceName
# Should show: AMD Radeon Graphics (RADV GFX1013)

# Check governor running
systemctl status oberon-governor
# Should show: active (running)

# Check GPU frequency
cat /sys/class/drm/card0/device/pp_dpm_sclk
# Should show multiple frequencies, one marked with *

Step 7: Install Steam & Gaming Tools

sudo dnf install steam mangohud goverlay

# Enable Steam Proton for Windows games
# In Steam: Settings → Compatibility → Enable Proton for all titles

Step 8: Test a Game!

Launch a game through Steam. Most games work out of the box with Proton.

For launch options in Steam (right-click game → Properties → Launch Options):

RADV_DEBUG=nohiz %command%

This fixes graphical glitches in some games.

Quick Troubleshooting

No Display

Problem: Black screen during/after installation Solution: Boot with nomodeset parameter (added automatically in Fedora Basic Graphics Mode)

GPU Not Detected

Problem: vulkaninfo shows llvmpipe instead of AMD GPU Solution:

  1. Verify Mesa 25.1+ installed: dnf list mesa-*
  2. Check kernel version: uname -r (should be 6.15.7-6.17.7 or 6.12-6.14 LTS, NOT 6.15.0-6.15.6 or 6.17.8+)
  3. Verify nomodeset was removed from GRUB

Poor Performance / Low FPS

Problem: Games running at 15-20 FPS Solution:

  1. Check governor is running: systemctl status oberon-governor
  2. Check GPU frequency: cat /sys/class/drm/card0/device/pp_dpm_sclk
  3. Should NOT be stuck at 1500MHz

High Temperatures

Problem: GPU hitting 90°C+ Solution:

  1. Verify fans are spinning at full speed
  2. Straighten heatsink fins (they're often bent)
  3. Replace thermal paste
  4. Use high static pressure fans (Arctic P12 recommended)

Performance Targets

You should achieve:

  • Idle: 40-60°C, 50-80W power draw
  • Gaming: 70-85°C, 150-200W power draw
  • FPS: 60+ in most games at 1080p medium-high settings
