PC CMOS Cleaner 2.0 is an older, specialized "offline" software utility designed to recover or reset lost BIOS/CMOS passwords . Unlike modern PC "cleaners" like that focus on file junk

, this tool is a bootable Linux-based recovery environment that interacts directly with the motherboard’s CMOS chip. Core Functionality

The primary purpose of PC CMOS Cleaner 2.0 is to regain access to a computer when the BIOS-level password has been forgotten or lost. It operates through two main methods: Password Decoding

: It attempts to decrypt and display the existing BIOS password. CMOS Reset

: If decoding fails, it can wipe the stored CMOS data entirely, effectively resetting the BIOS to factory defaults and removing the password. Compatibility

Because it boots from its own environment, it does not require an installed operating system like Windows or Linux to function. It is compatible with major BIOS manufacturers, including: AWARD, AMI, Phoenix, and Compaq.

Hardware brands like Samsung, IBM, Sony, Toshiba, and ThinkPad. Systems using x86 and x86_64 architectures. How to Use via USB Boot pc cmos cleaner 2.0 usb boot

While originally distributed as an ISO for CDs, it can be deployed via a bootable USB drive. Preparation : Download the PC CMOS Cleaner ISO file. : Use a tool like to flash the ISO onto a USB drive. : Plug the USB into the target PC, restart, and enter the

(often F12, F11, or Esc) to select the USB drive as the primary boot device.

: Once the environment loads, follow the on-screen prompts to either "Get Password" or "Wipe CMOS." Important Considerations Data Impact

: Resetting the CMOS will revert all BIOS settings—such as boot order, overclocking profiles, and system time—to factory defaults. Legacy Tool

: PC CMOS Cleaner 2.0 is an older utility. On modern systems with UEFI Secure Boot

or TPM-encrypted BIOS, it may be less effective or require disabling Secure Boot to run. Physical Alternatives

: If software fails, most motherboards can be manually reset by removing the CR2032 battery for a few minutes or shorting the pins with a screwdriver. step-by-step guide

on creating the bootable USB using a specific tool like Rufus? Speed up, optimize and clean your PC for free - CCleaner

It sounds like you’re referencing PC CMOS Cleaner 2.0 — a utility often used to reset or clear CMOS memory (BIOS settings) via a bootable USB drive.

However, a few clarifications are important:

  1. No official tool named “PC CMOS Cleaner 2.0” exists from major motherboard or BIOS vendors. The name appears in some third-party tools, DIY boot disks, or older forum posts — often as a renamed DOS utility or batch script that clears CMOS by writing to I/O port 0x70/0x71 or resetting BIOS configuration data.

  2. USB boot means you create a bootable USB (e.g., with FreeDOS, or using Rufus) containing that utility. Booting from it would automatically clear CMOS settings without needing to open the case or use the jumper.

  3. Possible risks: Incorrect use could corrupt BIOS settings (rarely, BIOS flash) or fail on modern UEFI systems. Most modern motherboards have a “Clear CMOS” button, jumper, or battery removal method that’s safer.

If you’re trying to clear CMOS via USB boot:

  • Use a known tool like KillCMOS or simply a FreeDOS boot with a script that runs DEBUG to write to CMOS ports.
  • Or better — use motherboard’s own CMOS clear method (jumper/battery/button).

PC CMOS Cleaner 2.0 is a specialized bootable utility designed to reset, recover, or delete BIOS/CMOS passwords and restore BIOS settings to factory defaults without needing to physically open your computer. It is particularly useful for x86 and x86_64 systems where the BIOS password has been lost or forgotten. HP Support Community Key Features of PC CMOS Cleaner 2.0 Universal Compatibility : Supports a wide range of BIOS brands. Password Recovery

: Can display "superior" (master) passwords or completely remove them. BIOS Reset

: Automatically reverts BIOS settings to their default factory state. Bootable Format

: Typically used by creating a bootable USB or CD, allowing it to run independently of the installed operating system. HP Support Community How to Create and Use a Bootable USB

To use this tool, you must create a bootable environment since it runs in a pre-boot state: Download the ISO : Obtain the PC CMOS Cleaner 2.0 ISO file from a reputable source. Flash to USB : Use a tool like to "burn" the ISO onto a USB drive. Configure Boot Order Restart your PC and enter the (common keys include F12, F11, or Esc). Select your USB drive as the primary boot device. Run the Utility

: Once booted, follow the on-screen prompts to either reveal the current password or clean the CMOS settings entirely. HP Support Community Alternative Manual Methods

If software-based cleaning fails, you can reset the CMOS manually using these physical methods: CMOS Battery No official tool named “PC CMOS Cleaner 2

: Power down the PC, remove the coin-cell battery for 1–5 minutes, then reinsert it. Motherboard Jumper

: Move the jumper cap from pins 1-2 to 2-3 for several seconds, then move it back to the original position. Dedicated Button

: Many modern high-end motherboards feature a "Clear CMOS" button on the rear I/O panel or the board itself. Reset BIOS password (HP 6530b) - HP Support Community

Date: October 26, 2023

Prepared For: End Users seeking BIOS/CMOS password recovery or reset solutions.


Why "2.0" Matters

The original PC CMOS Cleaner used a simpler DEBUG.exe script. Version 2.0 automates the process with a pre-configured bootloader. It works on legacy BIOS (Pre-UEFI) and many modern UEFI systems in legacy CSM mode.


Using Rufus (Windows):

  1. Insert USB drive (backup data first – it will be erased).
  2. Run Rufus as administrator.
  3. Device → Select your USB drive.
  4. Boot selection → Choose “Disk or ISO image” → Click SELECT and pick your PC CMOS Cleaner 2.0 ISO.
  5. Partition scheme → MBR (for BIOS/Legacy) or GPT (for UEFI). Try MBR first.
  6. File system → FAT32.
  7. Click START → If prompted, write in DD mode.
  8. Wait for completion.

⚠️ Troubleshooting & Warnings

  • Tool doesn’t boot → Try a different USB port (USB 2.0 preferred) or recreate with DD mode in Rufus.
  • Black screen after boot → The tool may be incompatible with UEFI or newer chipsets (post-2015).
  • Suspicious files → If the tool asks to write to hard drive or install anything, power off immediately.
  • Legal use only – Unauthorized BIOS access is illegal in many jurisdictions.

Use Cases

  • Refurbishers & repair shops – Quickly reset dozens of PCs without opening each one.
  • Corporate IT – Recover locked legacy machines after employee departures.
  • Overclocking recovery – Instantly clear unstable RAM/CPU settings without clearing the case.
  • Education labs – Reset student-altered BIOS configurations in seconds.

Part 1: What is PC CMOS Cleaner 2.0?

PC CMOS Cleaner 2.0 is a freeware utility designed to reset CMOS (Complementary Metal-Oxide-Semiconductor) memory without physically opening the computer case or removing the motherboard battery.

Unlike basic CMOS reset tools that simply clear the date and time, version 2.0 specializes in debugging the I/O port (usually port 0x80 or 0x70/0x71) to overwrite BIOS checksums. This effectively:

  • Removes BIOS/CMOS passwords (Supervisor, User, HDD passwords).
  • Resets overclocking settings that cause boot failures.
  • Recovers corrupted firmware settings after a failed BIOS update.
