    Re: HP Elitebook 820 G2 bios needed

    I figured it out. The writing problem that i was having was caused by my soic clip making a poor connection. I will let you know the results after i am able to flash the chip.

        I'd recommend not using a SOIC clip but rather desoldering the chip to read it out of circuit.

                        Is there a Tutorial how to backub bios dump?

                        You need SPI programmer for that (for example CH341A or raspberry pi, using flashrom software).

                        Where can I download the software_

                                    Read bios chip again and verify.

                                        But did you verify aswell? Simply reading again is not enough.

                                            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...

                                            I have this laptop that does boot but it's on an older BIOS that has issues with Secure Boot, and I cannot use the normal Razer BIOS updater because for some reason the serial number is missing / got deleted somehow (Common issue on this model, from what I've read). I got a dump of the BIOS chip (or at least what I think is the BIOS chip), and its 16MB in size - the files from the Razer BIOS update are 8MB. (There's two 8MB files, am I supposed to combine these somehow? Or combine with an Intel ME firmware? I have no idea).
                                            So, I'm looking for a BIOS dump for this machine - a 16MB one....

                                            Hello,

                                            I badly need bios dump for HP DM1-4000er,

                                            Model: HP DM1-4000er
                                            Motherboard: DA0NM9MB6D0 REV.D
                                            Product: QJ490EA#ACB

                                            Please help. My bios chip burned so I don't have the old bios anymore. I need bios dump before I can install the replacement.

                                            I need a BIOS dump for the Samsung S49CG934SU monitor
                                            by Habble7
                                            The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                            Suspected Cause:
                                            I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                            Troubleshooting Attempts:

                                            Nuc7i5BNH Bios Dump Needed
                                            by rednix01
                                            Hi everyone,

                                            I accidentally bricked my NUC7i5BNH after disabling the option to boot from USB, and now it's not showing any display at all. I tried the USB recovery method, but unfortunately, it didn't work.

                                            Local repair shops are quoting around $150 just to flash the EEPROM, but considering the unit is only worth about $75 these days, that’s not really an option. So I'm hoping to learn how to flash the chip myself. But to get started, I need a working BIOS dump for the NUC7i5BNH.

                                            I did come across a post with a dump for the NUC7i7BNH, but I wasn't sure...
