Restart your computer. Upon reboot, the BIOS password should be gone, and settings will be reset to default. Troubleshooting & Safety
Your motherboard keeps configuration settings (like boot order, system clock, and security passwords) inside a small volatile memory chip called the Complementary Metal-Oxide-Semiconductor (CMOS). This chip requires a continuous power supply from a coin-cell battery (CR2032) to retain data.
Reboot your PC immediately. During the boot sequence, you should see a message indicating a or "CMOS Defaults Loaded" . This indicates the tool worked perfectly. Press the indicated key (usually F1, F2, or Del) to enter the newly unlocked BIOS menu and reconfigure your system settings. Important Safety and Risks
The application interface is minimal. Click on the main dropdown action menu and select or "Invalidate Checksum" . Step 4: Execute the Wipe download cmos deanimator v21 link
CMOS De-Animator v2.1 is a specialized system utility designed to invalidate the checksum of your motherboard’s CMOS memory. By intentionally corrupting this checksum, the application forces the motherboard to reset all BIOS settings to their factory defaults during the next system boot. This automated reset effectively clears supervisor passwords, user passwords, and custom hardware configurations that might be preventing system access or stable operations.
Because this application utilizes low-level kernel drivers to interact with hardware ports, Microsoft Defender and other Antivirus suites may trigger a False Positive warning (often flagged as HackTool or Potentially Unwanted Application ). If you download the file from the trusted links above, you can safely ignore this warning or temporarily add an exclusion rule to your antivirus. Step-by-Step Usage Guide
To help find the right version for your specific motherboard, let me know: Restart your computer
Verify the file integrity using a SHA-256 checksum utility if provided by the host. Step-by-Step Guide to Using CMOS De-Animator v2.1
Standard desktop motherboards store their access passwords directly inside the volatile CMOS RAM chip. Wiping the CMOS successfully resets the password.
Then you’ll understand why, twenty years later, the search continues. This chip requires a continuous power supply from
Allows you to create a backup of your current CMOS settings before clearing them, allowing for a revert if necessary.
When CMOS De-Animator runs, it flashes or disrupts this specific storage area. On the next system reboot, the motherboard detects that the CMOS checksum is invalid, wipes the corrupted settings, and automatically restores all BIOS settings back to their original factory defaults. This effectively removes any local BIOS supervisor or user passwords. Key Features
In some cases, specific laptop brands (like Lenovo) have advanced security, requiring you to use specific versions or the bootable version to bypass the supervisor password.
The software includes several key features to help you regain access to your computer:
