BIOS image for an MSI laptop identified by board numbers MS-1582 and MS-15821, shipped as a 13.7 MB RAR. MSI uses the MS-1xxx pattern for notebook models and the extra digit form for the board variant, so check which code is printed on your mainboard. The dump is meant for rewriting the SPI BIOS chip with a programmer when the laptop fails to boot. Back up the original chip and confirm the extracted image size matches the flash capacity before writing.

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 →
