    HP DV6 6C65el (MB Winstron 48.4RH09.021): split BIOS file to direct flash

    Hello. This notebook arrived dead. Tryied to reflash the SPI eprom with files of SIMILAR motherboard and it turned to life. Now I tryied to update BIOS downloading it from HP site, but the executable says "this bios is not for your computer" (I guess it depends by the current BIOS not perfectly compatible with the board..).
    I'm thinking to desolder the chips and reflash it with my programmer with the correct files, but the file provided by HP is a merged file containing either main bios and EC bios, and I haven't found the separated files for my model.
    So I need help: can I split the file in two single files and flash it separately?
    I don't want to leave the current bios because I cannot use the WIFi board, and there are some minor issue that I think are related with the wrong BIOS.

    If it can help, I attach the original damaged bios files, and the currentlt installed files, probably dedicated to the dv6-6b54er model.

    The file I have to split is contained in the archived file downloadable from HP site:
    http://ftp.hp.com/pub/softpaq/sp60501-61000/sp60655.exe

    Thank a lot for any help!

      welcome to forum

      bios for this board is strange to say at least

      in SP60655 there are two bios with same BID but thay are not the same so i cannt be sure which one is it so you must try both... thay are already latest version

          Thanks a lot ala_borbe! In the HP_TOOLS partition of the notebook there's already a folder BIOSUpdate with the bin file which I think is the original version. Do you think that comparing the bin file with each one of the file contained in the archive from HP I can realize which version I have to flash of the files your provided?
          Moreover, what can I use to split future BIOS in Main and EC file?
          I tryied PhoenixTool (which works also with Insyde EFI BIOS), but seems a little more complicated for my current knowledge of the BIOS structure...
          Thanks a lot again!

              there is no generic way for that, nor tool cos its not the same every time, depends on construction of board and vendor

              at least i did not found any for for that, i do it manually with hex editor

              to help a bit:
              hp bios in most cases is encrypted meaning not readable content so the trick is to decrypt first... sometimes PhoenixTool can do this (in your case it can) that is the file with .dec extension
              sometimes it cannt but there are other methods for that

              finding where to cut big file is mostly easy if you have dump
              in big file do hex search to find where it starts, and size is known
              but in this case updated EC rom is 128k and eprom is 512k... simply pase 128k over bigger file, not touching the rest cos it wont turn on, it would be dead like horse

              now for serial part and dmi data... do search for text for model name and note adresses in hex and paste it to new bios at same address (in your case it 0x00180000 if i recall right)

              Using hex editor look at the end of bios and near end there would be BIDxxxx and that is how you can identify right bios

              i hope i made my self clear, and not to confusing

                                  Hi all,

                                  My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
                                  The charging red LED lights up, but the charging screen doesn't show any indication.
                                  When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
                                  (I've tried removing the battery and resetting the device, but the issue persists.)

                                  NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)

                                  Lenovo ThinkStation P520 BIOS file needed
                                  by Forest79
                                  Hello,

                                  I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
                                  The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

                                  However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...

                                  Hello Everyone,

                                  I have Thinkpad T560 Which has corrupted BIOS. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need a bin file for the BIOS. I was able to extract the .exe file of BIOS from Lenovo given here in this link:

                                  https://pcsupport.lenovo.com/au/en/p...me=BIOS%2FUEFI

                                  In the extracted files, I see that BIOS containing file has extension .FL1 and I need to extract or convert it...

                                  BIOS file for ASUS F542UN laptop
                                  by Sebastian Codrean
                                  Hello to all of you! I need help with a BIOS file.
                                  The BIOS chip is fried on my Asus F542UN laptop, and I bought a new chip that needs programming. I have a CH341a programmer but I need a .bin BIOS file. On Asus support page the firmware has another extension, .310 and from reading on this forum I understand that that file is not complete BIOS.
                                  So, in short I need the "complete" BIOS .bin file to flash on the new chip. Another issue is that on back of the case the label says F542UN but on the sticker on the motherboard it's X542UN.

                                  Hello everyone,

                                  I soft BRICKED my Lenovo IdeaPad laptop (black screen with led lights on, responsive keyboard backlight, fans spinning) after messing about with a Github tool called Smokeless. I am now attempting to reflash the bios through USB, but I am not sure if I extracted the correct BIOS ROM file to flash, and I also could not find the correct file name to rename it to (GLCrisis.bin, GLCN.bin, Currom.bin??). In addition to attempting to reflash the Bios with a USB, I have also performed the following activities:
                                  *Novo button power on
                                  *Disconnected internal battery...
