Re: bios macbook a1278 820-3115-b
Hi I have tried all three dumps with a T866A programmer but unfortunately I have not been successful. If I do not uncheck "check id" option the flash does not start and if I uncheck it programming starts but after the first step it stops giving this error:
Error! Code Address 0x000000 Buf_Val 0xFF IC_Val 0x00
Can anyone helps me?Comment

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
Troubleshooting Attempts:

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
This laptop is the same laptop I was working on in this thread and I wasn't sure if I should post a new topic or post in that thread because I already solved the issue that thread was discussing and this is a completely different issue although it is dealing with the same laptop. I decided to make a new thread since it's a new issue, but please move if I made a mistake.

Hi,
I need a BIOS dump for MSI Z590 PRO WIFI from a real physical board, along with MAC address and serial no.
It must be a dump from a physical board, as it contains personalized data eg. MAC Address, UUID, Serial no.
I have a board which has lost the BIOS contents, I have the MAC and serial to this board, and need to insert it into the another BIOS image. To do it, I need to have a real image from a real board, as the images from the MSI site are without this data. The only way to find where MAC/UUID/Serial is located in the BIOS is to have a bios...11-06-2022, 05:22 PM -
I have this laptop that does boot but it's on an older BIOS that has issues with Secure Boot, and I cannot use the normal Razer BIOS updater because for some reason the serial number is missing / got deleted somehow (Common issue on this model, from what I've read). I got a dump of the BIOS chip (or at least what I think is the BIOS chip), and its 16MB in size - the files from the Razer BIOS update are 8MB. (There's two 8MB files, am I supposed to combine these somehow? Or combine with an Intel ME firmware? I have no idea).
So, I'm looking for a BIOS dump for this machine - a 16MB one....
