BIOS dump for a Z97-K desktop motherboard, version 2901 dated 31.03.2016, intended for a 25Q64FVA1Q SPI EEPROM, which is a 64 Mbit (8 MB) Winbond flash part. The archive is about 4.9 MB packed. Such an image is written with a hardware programmer like the CH341A when the board is bricked after a failed update. Back up the existing chip before writing, verify the chip marking matches 25Q64, and expect board-specific data such as the MAC address to need restoring afterwards.
