Working BIOS dump for a Lenovo motherboard with the code I3X0MS, version 1.0, stored in a RAR archive of about 16.4 MB. The code points to a Lenovo desktop board of the Intel 300-series chipset family, but the name does not state a specific PC model, so match the label on the board itself. Technicians write such images to the SPI flash with an external programmer when a system will not post. The archive may contain several files, so inspect it, save the original dump and confirm the size fits the chip.
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.

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 →
