BIOS firmware archive for the ASUS M5A78L-M LX motherboard in a BR variant, with a 1101 tag that most likely marks the BIOS version. The SI suffix is not explained by the name. The 787 KB RAR should hold the flash image used to recover a board that fails to POST after a corrupted update. Extract it and confirm the image matches the capacity of the SPI chip on the board. Dump and keep the original chip contents with a programmer before writing, and check that the board revision on the PCB corresponds to this variant.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
