BIOS image for MSI boards MS-1682 and MS-16821, sized for a 1MB flash chip and packed in a small RAR of about 491 KB. The same board appears in the MSI CX500 schematic set. A 1MB SPI chip is typical of older notebook designs, and the file must match that capacity exactly. Use a programmer to rewrite the chip when the firmware is corrupted and the machine will not POST. Read and save the existing chip first, and confirm which of the two board variants is fitted.
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 @biosarchive. Enginerys does not host this file.

How to open a .rar file
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 →
