This is my original bios

the bios posted is half empty...The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Good evening. Thank you for your answer! Yes, at first I read the chip unsoldered with pliers. Then I unsoldered the chip and deleted it. I programmed another bios from the depths of the Internet, but my computer did not work. The caps lock blinks like before. Now I need a completely new and correct bios dump file. I am not smart enough in this matter to prepare a new bios myself. Maybe one of the bios posted on this site will work for me? Thank you!

[Agris]

I don't understand how you can find post #23,30.

[peste]

Good morning. Thank you very much for your help. My bios worked, I just need to sort out the serial numbers. Could you please correct the serial numbers in my dump, which I would take from my corrupted dump that I sent earlier? Now I will attach the dump that is working. Thank you.

I wanted to fix the serial numbers myself, it turned out that the mpm was blocked. I tried to unlock the mpm with various programs, but it didn't work.
