Description
BIOS dump for the ASRock Z77 desktop motherboard, supplied as a ZIP archive of about 4.3 MB under the original file name ASRock Z77 Extreme4_2.90.zip. The file name suggests an Extreme4 board with BIOS version 2.90, but the facts do not give a board number or revision, so confirm the exact model and PCB revision on your own board before using it. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update.
The catalog also lists 3 schematics, 8 boardview files, and 3 BIOS dumps for the ASRock Z77.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: ASRock Z77. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
