Raw 8MB BIOS binary for the ASUS S500C laptop, with S203 appearing to indicate the firmware version. A bin file like this is written directly to the SPI flash with a programmer such as a CH341A when the board is bricked or the BIOS is corrupt. The 8MB size should match a 64Mbit chip, so confirm the chip capacity before flashing. Always read and save the original chip first, since it holds board-specific data like serial numbers and network addresses.
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.
