If you encounter security prompts while launching Arena Breakout: Infinite on PC, your system likely lacks the hardware features needed for the B.D.C security feature's DMA Protection shield. To fix this, you need to manually enable VT-d for Intel or IOMMU for AMD in your computer's BIOS settings.

Quick Overview: How to Enable DMA Guard

  1. Check your motherboard manufacturer and CPU type using Windows system info.
  2. Restart your PC and tap your manufacturer's specific BIOS entry key.
  3. Locate and enable VT-d (Intel) or IOMMU (AMD) in the BIOS menu.
  4. Save changes and boot back into Windows.

Step 1: Identify Your Motherboard and Processor

Before entering your BIOS, verify your hardware specifications so you know which keys and menu paths to use:

  • Press the Windows Key + R on your keyboard.
  • Type msinfo32 and hit Enter.
  • Note your "System Manufacturer", "Motherboard Manufacturer", and "Processor".

Step 2: Enter Your PC's BIOS Settings

Restart your computer. As soon as the screen lights up and before Windows loads, rapidly tap or long-press your manufacturer's entry key:

  • ASUS: F2 or DEL
  • Gigabyte: F12 or DEL
  • MSI: DEL
  • HP: F2, F10 (Laptops), F12, or ESC (Desktops)
  • Dell: F2 (sometimes F12)
  • Lenovo: F2 or Fn+F2 (F1 for ThinkPads)
  • Acer / Sony: F2
  • Toshiba / IBM / ThinkPad: F1 or F2 during Cold Boot

Step 3: Enable VT-d or IOMMU by Manufacturer

Navigate through your BIOS using the platform-specific paths below to locate and enable the required settings:

HP

  • Intel: Go to Advanced -> Check VT-d and DMA Protection.

Lenovo

  • Intel: Go to Security -> Virtualization -> Check Intel VT-d Feature and Kernel DMA Protection.

ASUS

  • AMD: Go to Advanced -> AMD_CBS -> Set IOMMU to Enabled (also check DMA Protection and DMAr Support in NBIO Common Options if available).
  • Intel: Go to Advanced -> System Agent (SA) Configuration -> Set VT-d to Enabled (set Control IOMMU Pre-boot Behavior to Enable IOMMU during boot).

MSI

  • AMD: Go to Overclocking -> Advanced CPU Configuration -> AMD CBS -> Set IOMMU to Enabled (also check DMA Protection and DMAr Support if available).
  • Intel: Go to Overclocking -> CPU Features -> Set Intel VT-D Tech to Enabled (set Control IOMMU Pre-boot Behavior to Enable IOMMU during boot).
