                  It's a Winbond 25Q80DVNIG, 3.3V, 8 Mbits

                  Backup was done with AsProgrammer, I made a second backup using NeoProgrammer but this one could only be detected as 25Q80BV.

                                        Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
                                        by Ahari
                                        Hi all,

                                        This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

                                        I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

                                        I...

                                        (Request) MSI PRO B660M-A DDR4 (MS-7D43 Rev 1.0) Bios Dump
                                        by Junhijam
                                        Hi, I'm new to all of this so I hope I'm doing correctly and not breaking any rules.
                                        I need help for my MSI PRO B660M-A DDR4 motherboard BIOS dump.
                                        The motherboard got bricked during BIOS update due to a power cut in my village while updating BIOS. Now the PC is not booting. Fans kept spinning and no display is coming.
                                        A local technician said I need the full BIOS dump/file for this motherboard.
                                        My Motherboard model is:
                                        MSI PRO B660M-A DDR4
                                        MS-7D43 REV 1.0
                                        The Bios chip is:
                                        MXIC
                                        MX25U25673GZ4140

                                        Please, if anyone has the same board...

                                        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:

                                        Hi, Thanks for all you do here.

                                        I have attached my 16MB dump.

                                        EDIT2: All hardware working fine, I think I just need to update my linux booatloader and all gucci
                                        EDIT:
                                        I can get into bios now! I reflashed as instructed elsewhere. With a minimal POST (just 1 stick of ram , GPU, CPU, no drives) I have loaded into BIOS. I am about to reinstall my other hardware components now.

                                        The clips are such a pain to use, soldering would be a great skill to have.

                                        Thanks for the advice in other threads!

                                        To answer my own question, I didn't...

                                        BIOS Dump for Lenovo Yoga Slim 7 15ILL9 (83HM) LNVNB161216
                                        by dragic98
                                        Model: Lenovo Yoga Slim 7 15ILL9
                                        Machine Type Model: 83HM

                                        TLDR: I would like to have the clean BIOS dump file for my laptop model.

                                        Issue: First, my speaker wasn't working/showing up, so I downloaded the recommended BIOS update (from Jan 4, 2026) on Lenovo Support for my laptop. This didn't fix the speaker issue after restarting, so then I shut it down and pressed the power button for 60 seconds to perform a reset. I'm guessing I somehow messed up the BIOS because now the laptop won't turn on even after trying the NOVO button on...
