BIOS archive for the MSI Modern 15 A5M laptop, mainboard MS-155L1 version 2.0. MSI designs its own boards and marks them with MS-xxxx codes, so the number on the PCB is easy to compare against this file. A dump like this lets a technician recover a unit that no longer posts by reprogramming the SPI flash chip with a programmer such as a CH341A. Confirm the board revision is 2.0 before flashing, make sure the image size matches the chip, and keep a copy of the original read in case you need to roll back.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
