        Found this
        "The Nuvoton NPCE586HA2MX is a programmable keyboard controller (KBC) used in various motherboards, including models DA0X8CMB6E0 REV E and DA0X81MB6E0 Rev E. It is noted that the system is pre-programmed during production, eliminating the need for additional programming after replacement."

        So it is programmed by bios?

            Lenovo P14s Gen 5 SVP unlock
            by Syseng
            This sums up discussion related to Lenovo P14s Gen5 in this thread. Credits go to Sbaro and especially Maxpower3. The locked dump is attached.

            The device is based on NM-F871 motherboard with Nuvoton NPCK397 series controller. The motherboard also contains three BIOS chips: two different Winbond chips for main BIOS and external EC flash, and also a Gigadevice chip which purpose I do not know. The password information is contained directly in controller and thus can be manipulated by reprogramming it, so reprogramming BIOS chips is technically not required, however you may wish to make...

            HP Omen 15-dh0052nf power-on & bios password
            by Nopslide
            Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

            My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

            Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

            Dell Latitude 5520 - dump bios to obtain password
            by iwu
            Hello,

            I am not experienced in electronics, but I really want to check if my idea is possible.

            I have motherboard replaced from Dell Latitude 5520 (11th gen on i5 CPU).
            BIOS/UEFI access on that MB/PC is blocked by password which I want to get it know - even if I need some bruteforcing or stupid manual activities.
            There was no computrace activated.

            I was happy when I saw many posts about removing BIOS password based on .bin file dummps. I wanted to go little further - get to know the password from the dump.

            1. I do not know how thebios...
