UPDATE: The problem is partially resolved.
I flashed the backup file without any errors. I rebooted and everything was fine. But still, I can't flash the new image.
I think some sections of EEPROM are locked for writing (for example, the booting logo). Could it be?
Best regards, Ivan.

Save my ass from burning, please! :_)
It is an OEM PC. I just wanted to replace the OEM BIOS with the original one. I have checked the formats, the headers of the backup file and the downloaded one are equal.
Well, I'll have big problems if this PC won't boot up. At least I will need to pay a bunch of money for repair or wait for the programmer to arrive.
I hope you will help me, I will answer all the questions and provide any new information.
Thank you very much for your attention, Ivan.
