    reset bios password x409dl (asus D509D)

    Hello,
    I want to clear the bios password in a Asus VivoBook D509DA-EJ098 but after that now ask me a different password which I don't know. I have tried several ways like ALT-R key combination but it seems that is for old ones bios.
    Anybody know if it is possible reset the bios any way (jump some pins for example)???

    Thanks in advance.
    Regards.

    Please post the serial number,and read the "BIOS guides, methods, resources and tools" thread https://www.badcaps.net/forum/showthread.php?t=103570

    You might be able to use the AMITSE method, don`t know,you havn`t posted a backup.

        this is NOT the "bios of this laptop", it's an update from the Asus site. Read the RULES of this site if you want to get help and don't waste our time with such BS.

          Ok, sorry I didn't understand the request well at first. I can not get a dump or a backup of the actual bios, as I said when I tried to cleaer the password something was wrong and now ask for a different password.
          Sorry again I didn't want to waste your time.

          Thanks.

                    the original bios from the laptop must be extracted using a reader/programmer like CH341a Memory Programmer.

                        ASUS TUF GAMING Z790-PLUS WIFI - BIOS Help
                        by grimacelord
                        Hello,

                        I have spent the last hour on this and I guess this is just over my head, so here I am.

                        I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.

                        The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.

                        Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...

                        [REQUEST] ASUS TUF A15 FA506NF (2021) - Clean BIOS dump needed (UEFI Password locked)
                        by ArkzG
                        Hey guys, I have an "ASUS TUF Gaming A15 FA506NF (2021)" that's locked with a UEFI password, I need to reprogram the BIOS chip but can't find a clean ".bin" file for this specific model, I've tried the official BIOS updates from ASUS support page, but they're 32MB updaters that don't extract to a usable 2MB .bin file for direct chip programming.

                        What I currently have available:
                        - Model: FA506NF (2021)
                        - BIOS chip: GD25LQ16 (16Mbit/2MB)
                        - Tools: CH341A programmer ready to use

                        Does anyone have either a clean 2MB .bin dump of this model,...
