BIOS image for the Sony VAIO VGN-AR series, supplied as a 1.00 MB raw binary. The name gives only the model family, with no board number, revision or version, so the exact motherboard it came from is unknown. A dump like this is normally written to the SPI or LPC flash chip with a hardware programmer when a laptop will not POST after a failed update. Before flashing, read and save the original chip contents, confirm the chip capacity matches the 1 MB image, and check that the board in hand really belongs to the VGN-AR line.
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.
