MSI firmware for the MS-16U81 board, version 101, in a ZIP of 47.0 KB. MS- followed by a number is MSI's own board numbering, with the trailing digit marking a sub-version. Given the small size, this is likely an embedded controller image rather than the main BIOS. EC firmware controls power-on, charging and fans, so mismatches can cause no-power faults. Confirm the board number and EC chip type, and back up the existing firmware before flashing.
