Dear Operators,
Firstly, we would like to invite all Operators to confirm your PC settings.
Please refer to: Kernel DMA Protection | Microsoft Learn
Figure 1
Figure 2
This is A.C.E.'s newly launched upgraded DMA hardware feature protection function. Based on the existing Windows security feature 'Kernel DMA Protection', it further enhances protection against external abnormal hardware, preventing unauthorized access to memory by external hardware devices and avoiding DMA attacks; thereby protecting your account from malicious exploitation.
If you receive:
Figure 1, please read 'I. Operation Guide - How to Enable Figure 1’s Feature' below.
If you receive:
Figure 2, please read 'II. Operation Guide - How to Enable Figure 2’s Feature' at the end of the article, or restart your system to enable to relevant function
I. OPERATION GUIDE - HOW TO ENABLE FIGURE 1'S FEATURE
You need to access the BIOS page and enable the corresponding option within the BIOS.
Depending on your platform, the name of the switch may vary, specifically:
- Intel Platform: VT-D: Virtualization Technology for Directed I/O, Direct I/O Virtualization Technology
- AMD Platform: IOMMU: Input-Output Memory Management Unit, Input-Output Memory Management Unit provided by AMD processors
The following are some common motherboard BIOS entry methods for your reference.
If you are unsure of your motherboard brand, you may:
1. press Windows key + R, or
2. type msinfo32 in windows "Search" and press enter to view your motherboard brand (as shown in image above)
Restart your computer, and when a prompt appears on the boot screen/bottom of the screen, quickly tap/long-press the 'entry key'. The entry key will vary depending on the motherboard brand:
- ASUS: Usually F2 or DEL key.
- Gigabyte: Usually F12 or DEL key.
- MSI: Usually DEL key.
- HP: Laptops mostly use F2 or F10, some desktops use F12 key, or press the ESC key.
- Dell: Usually F2 key, some models use F12 key.
- Lenovo: Usually F2 or Fn+F2 key, some ThinkPad models use F1 key.
- Acer: Usually F2 key.
- Sony: Usually F2 key, some new models can use the ASSIST key.
- Toshiba: Press F1 or F2 during a cold boot.
- IBM/ThinkPad: Press F1 key during a cold boot, some new models can press F1 during a restart.
If you cannot enter the BIOS page according to the above tutorial, please contact your motherboard vendor or inquire about the BIOS entry method corresponding to your motherboard version.

Please click OK to restart and automatically enable 'DMA Hardware Feature Protection Function'.
Q & A
1. WHY DOES THE SECURITY TEAM REQUIRE THE ABOVE FEATURES TO BE ENABLED?
Some cheats may exploit the mechanisms of computer systems/other third-party antivirus software to obtain game data and evade security checks. To maintain a fair gaming environment for everyone, the Security Team needs to monitor certain mechanisms that might be exploited by cheats.
The Security Team recommends not to run other third-party software during gameplay in order to ensure your computer's security.
2. I DON'T USE CHEATS, WHY AM I REQUIRED TO ENABLE / DISABLE THE ABOVE FEATURES?
To prevent cheat programs from exploiting system vulnerabilities and undermining game fairness, the security system will require accounts with potentially abnormal login environments or security risks to enable DMA hardware feature protection. This will also enhance your account's protection capabilities, reducing the possibility of your account being maliciously exploited by others.
These measures provide preventive protection based on comprehensive security dimensions such as historical account login devices and network environments. We also advise all players to avoid sharing accounts, ensure passwords are secure, and avoid frequently changing network environments, which can pose risks to your account.
