BIOS image for the IQ270MS motherboard, with the name indicating a 16 MB flash size, stored in an 8.44 MB ZIP archive. The file is meant for reprogramming the board SPI flash when it fails to post, loops on startup or was damaged by a bad update. Check that the chip fitted on the board is indeed 128 Mbit, because an image that does not match the chip capacity will not fit. Read and save the existing contents with a programmer before writing, and confirm the model printed on the PCB matches IQ270MS.
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.
