Firmware dump from the small flash chip at U15 on MSI board MS-15621, version 1.0, marked as OK in the name, meaning a known-good read. It is a raw 1.00 MB BIN file, which fits a 1 MB (8 Mbit) SPI device and suggests EC or auxiliary controller firmware rather than the main BIOS. Use it when that chip is corrupted and the board fails to start or charge. Read the original first with a programmer and make sure the chip capacity matches the file.
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 @bios_main_ec_kbc. Enginerys does not host this file.
