MSI MS-155L1 VER 2.0 OK BIOS

BIOS .bin 16.0 MB Shared

Raw 16 MB BIOS image for an MSI laptop mainboard MS-155L1, version 2.0, marked OK, indicating a known-good dump. MSI designs its own boards, and the MS-xxxx number with a revision suffix is printed on the PCB. The .bin is intended for direct programming of a 128 Mbit SPI flash with a CH341A, RT809 or similar programmer. Make sure the board version matches 2.0, keep a copy of the existing chip contents, and confirm the chip on the board is 16 MB so the image fits without truncation.

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_laptopomi. Enginerys does not host this file.
