                                        Bios password removal on a Unowhy dump

                                        Hi Everyone,

                                        I'm facing a problem with a locked bios with a password and i can't find how to remove it...

                                        The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).

                                        the Computer is a Unowhy small pc

                                        After failling trying to boot on other "none Windows" partition, i wanted to try to remove the bios password.

                                        My first attempt was to get the bios dump from windows...

                                        TONGFANG "GM7TG7P" Bios Password Problem?
                                        by traxformania
                                        Hello,

                                        I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

                                        But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

                                        I'm trying to reset my bios without success.

                                        I tried :

                                        -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

                                        MSI PRO B660M-G DDR4 - real bios dump from board needed (no stock bios)

                                        Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).

                                        I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...

                                        HP Elitebook X360 1030 G3 remove password BIOS.

                                        Password removal option for those who do not have a method through HPUnlocker.
                                        This option saves all information in the BIOS (serial number, Windows key, etc.) and also excludes the appearance of BIOS notifications at startup (hp endpoint security controller problem).

                                        1. Read BIOS (32MB) and EC (16MB) firmware.
                                        Be sure to make backups.

                                        2. EC:

                                        2.1) Copy the area from the original and paste into a clean "EC (16MB) Clean".

                                        Region start - 0, length - DA3000

                                        2.2) Find in "EC (16MB) Clean" and...

                                        Who has a MSI Z590 PRO WIFI - Need BIOS dump ?
                                        by DynaxSC
                                        Hi,

                                        I need a BIOS dump for MSI Z590 PRO WIFI from a real physical board, along with MAC address and serial no.

                                        It must be a dump from a physical board, as it contains personalized data eg. MAC Address, UUID, Serial no.

                                        I have a board which has lost the BIOS contents, I have the MAC and serial to this board, and need to insert it into the another BIOS image. To do it, I need to have a real image from a real board, as the images from the MSI site are without this data. The only way to find where MAC/UUID/Serial is located in the BIOS is to have a bios...
