    Hi everyone, I had a PC with a password protected bios. I disassembled the bios eeprom, not the rear one (EC), I read it, with the hexadecimal editor I edited it, I rewrote the eeprom, I checked it, I reassembled it and I find the PC in this damned state. I tried reloading the original file but nothing changes. I checked the connections several times, I was very careful with I only noticed that the eeprom when I give the erase command is not deleted neoprogrammer gives me an error as a programmer I used a ch341, I was very careful with the hot air. I can't explain what happened. Sorry for my English, I hope you can help me

              continues with the same problem as in the video. It's strange as soon as I turn on the power it starts blinking without even turning it on.
