          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...

          Common SPI bios chip programming Questions and Answers
          ----------------------------------------------------------

          Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

          A: If you can`t read from it how do you expect to write to it ?.

          Q: Why is my bios chip unreadable ?.

          A: The programmer is faulty or has a worn or broken zif socket.

          The USB cable is frayed,connector pins worn or some other physical damage.

          Not enough amperage or voltage to power the programmer properly.

          Toshiba Portege Z30-A - Burned Chip Identify
          by kodox
          received unit with no power at all, pluged bench PSU and not consuming any amperage, measurement shows that 19V only reaching first mosfet & gate voltage only 6V.
          visual inspection found that it has burned chip, marking code wasn't too clear under microscope, i guess it's "A C C I". the chip is located under huge diode with UCQ1QA03 marking on it, since i don't find any schematic or boardview for this model, wandering that someone had similiar board and kindly measure what voltage comeout from the inductor connected to that chip or maybe knew what model number of the chip...

          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...
