The CMOS settings are crucial for your computer's boot process. When you start your computer, the BIOS (Basic Input/Output System) reads the CMOS settings to determine how to configure the hardware and boot the operating system. If the CMOS settings are corrupted or incorrect, your computer may fail to boot or exhibit strange behavior.
By writing specific values to I/O ports 0x70 (CMOS address register) and 0x71 (CMOS data register), the tool corrupts the CMOS checksum just enough that the BIOS sees it as "invalid." On the next reboot, the BIOS automatically resets to factory defaults—including clearing any password. pc cmos cleaner 2.0 usb boot
