ASUS H110M-CS motherboard BIOS, with 4210 in the name most likely indicating the firmware version, stored as a 6.89 MB RAR. Use it to recover a board with corrupted firmware by writing the image directly to the SPI flash chip with an external programmer. Check whether the file is a raw chip dump or an ASUS capsule file, since capsule images need conversion or the vendor flash tool. Read and save the existing chip content first, and confirm the motherboard revision and chip size before writing.
