    Locate BIOS chip on Fujitsu D2156-S21 GS3 motherboard

    Hello,

    I have a Fujitsu motherboard D2156 that cannot post. So I suspect that BIOS became corrupted. However, I'm not able to locate a chip on the motherboard that could be the BIOS. The pictures are shown in the attachment. I have no idea where BIOS is located. Recently I have reprogrammed BIOS chip on Asus motherboard and it was 8 legs chip from Winbond.

    However this Fujitsu board is pretty different.
    Any help would be highly appreciated.

    Thank you!

          Thank you. I suspect this could be it. It is written on it ATMEL0729, 26F004, but there is also one more chip that has also ATMELxxx on it.
          Is it possible it has two?

                  Here are more detailed pictures.
                  The problem is that I cannot find a single, unique 8 legs chip on the board.

                      226F004 sounds like it could be a BIOS chip

                          That should be it on the 3rd picture, its near empty PLCC32 pads .

                                      Asus Chromebox CN62 - wrong chip put on BIOS reader
                                      by BMCappelletti
                                      Long story short:
                                      - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
                                      - gave the computer to his son a couple years later
                                      - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
                                      - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
                                      (seems like the story was not that short)

                                      He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

                                      Hello, first of all, excuse me, I am using the translator, English is not my native language.

                                      I have a Lenovo ideapad 330S - 14IKB laptop.



                                      The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

                                      Asus ROG Strix Scar G533qm with a G733qm Motherboard, can I modify the Bios to accept G533 Bios
                                      by glovecaps
                                      Hello,

                                      I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.

                                      My question is, can I update the Bios on this G733 motherboard to a G533 Bios.

                                      The reason for wanting to do this is that the keyboard isn't working as it should, and I think this...

                                      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...

                                      Lenovo T490 - motherboard serial - windows licence lost - after corrupt bios chip replacement
                                      by baletak
                                      Hi,
                                      had T490 with faulty bios chip. Bought chip out of ebay and soldered on. Laptop starts and works however serial numbers of laptop and motherboard do not match.
                                      I have updated laptop model number.

                                      1) I did not find the way to update laptop serial number - I have this one.
                                      2) I dont know where to get my motherboard serial number and how to update it. Is it somewhere physically on the mainboard? How do I update it?

                                      Hope to find someone to help me with this as I am hitting dead end at the moment.

                                      Many thanks

                                      Miro
