BIOS image for the ASUS Eee PC 1015BXO netbook, with 0609 in the name most likely marking the firmware version. The ROM file is 2.00 MB, so it is meant for a 16 Mbit SPI flash chip on the motherboard. Technicians write such an image with a programmer like a CH341A when a board will not post after a failed update or a corrupted chip. Read and save the original contents first, and confirm the flash chip capacity matches the image size. A mismatched dump will not fit or will not boot.
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 @bios_laptop. Enginerys does not host this file.
