Raw BIOS binary for a Lenovo board made by LCFC, number NM-C821 at revision 1.0, 8.00 MB in size. The name states no model or testing status, only board and revision. An 8 MB file matches a 64 Mbit SPI flash and can be loaded directly into programmer software such as the CH341A tools or NeoProgrammer. Before writing, read the original chip twice and compare the copies, keep the backup for serial and key data, and check that the board number printed near the PCB edge matches NM-C821 rev 1.0.
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 @CLRINDORE. Enginerys does not host this file.
