Compressed RAR package with firmware for the Sony VAIO VPCEB23FM laptop, 1.6 MB packed. The name gives only the model, so the archive should be opened to see whether it holds a full BIOS dump, an EC image or both, and what size each file is. VAIO boards of this era are often recovered by reprogramming the SPI flash with an external programmer. Confirm the motherboard number on the PCB matches the image, and read and store the original chip before writing anything new.
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.
