The way to clear the password is shared below:

1. Asustek's official website service supports searching for [ASMB6-IKVM] product, and then skip to the technical support page of the product. In the bar of [Driver and Tools ->BIOS and firmware], be sure to download the firmware of the motherboard corresponding to this module (see the firmware list for the corresponding motherboard model).

2. Unpack the downloaded firmware package (you will see two.bat files), make a pure DOS boot USB drive (recommended to make FreeDOS boot USB drive with Rufus), and put the unpacked firmware package into the boot USB drive. Boot from USB flash disk after boot, run [Flash2.bat] and continue according to the operation prompts. Flash1.bat refreshes the firmware but retains the original configuration information, and flash2.bat refreshes the firmware and initializes the default factory configuration (the password will also be cleared).

3. In the ASUS official website [ASMB6-IKVM] product support page, you can download the user manual, and open and configure the IPMI management login interface according to the manual and the corresponding motherboard manual
