ASROCK B85M-ITX P2.50 WORKING BIOS 100%

BIOS .rar 6.32 MB Shared

BIOS archive for the ASRock B85M-ITX motherboard, version P2.50, labelled as a fully working image, packed in a 6.32 MB RAR. A dump like this is used to revive a board with corrupt firmware by writing it to the SPI flash with a programmer such as CH341A or via the board recovery method. Check that the extracted image size matches your flash chip capacity, and save a backup of the existing chip first, since it holds board-specific data such as the MAC address that a generic image may not carry.
