        Having trouble uploading the file even though it's in a rar archive. Message says I cannot upload .bin files.

            Please attach as .zip or .rar, your Google drive link doesn't work (it's asking for login)

                  BIOS backup is empty, open with hex editor and it's full of 00 00 00 00 ...
                  BIOS should be 16MB, look for a chip with "128" on the name

                      The only chip I see with 128 on it is this one.

                        Looks like it's this one under the heatsink, WSON8 8x6 package

                          Here is the latest dump file. I am also posting a pic of the chip.

                            It's the correct chip W25Q128JV, but your backup is empty (FF FF FF ....), check connection with your programmer
                            You need a WSON8 8x6 probe like one of the pictures below if you don't want to desolder the chip; a SOIC8 clip won't work

                              OK. I was using the CH341a SPI BIOS 25xx/24xx series USB programmer with a SOIC8 SOP8 Test clip. I will need to get the item you mention. Thanks for your time and assistance.

                                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...

                                ASUS ZenBook UX480F : need help with cleaning the ME region of my BIOS dump
                                by mkdj
                                Dear all,
                                I have a ASUS ZenBook UX480F with the following symptoms:



                                I suspect it is a BIOS issue. So I decided to try to clean the ME region. I followed the guide on win-raid, and I believe I have done everything correctly. My problem is: when I open the outimage.bin in ME Analyzer, it says that it is Extracted, and not Region, Extracted as it should be. Is it normal, or did I do something not correctly? This is my first experience editing BIOS files.

                                I would appreciate if someone could take time to explain the issue, so that I can learn. But I would...

                                Hi,
                                I'm having difficulty figuring out how to get a working and properly sized bios for an Asus Zenbook UX425JA. The bios from Asus is 16.25 MB, whereas the XM25QH128A on the motherboard - which I am attempting to program with a CH341A - is 16 MB in size.
                                SN: L833NBLP0002CXMB
                                Thanks.
                                The bios from the website can be found here:...
