    How to check Dell BIOS dump integrity after downloading from chip

    Hello,

    Is there any known way to check Dell BIOS dumps integrity after downloading from the chip?
    I ask this to make sure that I don't get a corrupted dump.

    Thank you very much!

      I usually run it through UEFI tool, or MeAnalyzer for Intel machines.

          Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
          by acedogblast
          This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

          There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

          ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
          by DynaxSC
          Hi

          I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
          The SPI chip is an Winbond 25Q256JWEQ model (1V8).
          The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
          The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

          I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

          by ed1i
          Hello, I'm looking for bios chip on the motherboard on Dell Inspiron 7610. Server tag: CS4MDL3. I found on the back on the motherboard chip named: Winbond 25Q256JVEQ. Is it the right bios chip for this motherboard? I need to flash new bios on the chip, because it's stuck in infinity reboots. Is it possible this chip to be read AsProgrammer 25Q256JV option and ch341a programmer?...

          [REQUEST] 2MB BIOS Dump for Lenovo NM-E471 Rev 2.0 (Winbond 25Q16JWSIQ Chip)
          by hyperwood
          Hi everyone,

          Iā€™m looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.

          The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.

          I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā€“ and the last 2MB in those files are just FF FF FF....

          āœ… What I need:
          • A working 2MB BIOS dump
          • Matching NM-E471 Rev. 2.0, e.g. JY575
          ...

          Need help id'ing chip on a Dell g15 5515
          by donnietr
          Hello all,
          I have this dell g15 Ryzen Edition 5515. Board GDL56 LA-K453p. It had liquid damage when i bought it. Cleaned it up really well and then used thermal camera to see what got hot.
          Found the power pdw1 and pdw2 under the graphics card were getting hot. Pdw2 was hottest, i had a similiar chip on another board so i put it on this board.
          The other chip is now hot as well, which it was to begin with.
          Thats the problem as i dont know what to call it, like is it a mosfat? or what?
          I will attach a picture of both the boardlabel and of the area with the chips....
