Firmware archive for the Lenovo IdeaPad S10-3 netbook, 585 KB in RAR format, with no board number or revision in the name. Identify the motherboard from its PCB print and compare it with the archive contents before use, as S10-3 variants such as the S10-3c use other boards. The image is for programming the BIOS chip directly with a CH341A or similar tool. Read and keep the original contents, and make sure the binary size matches the chip so the programmer accepts it.
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 @afsbiosfree. Enginerys does not host this file.
