Working BIOS image for the ASUS ET2231I all-in-one board, revision 1.2, marked as fully functional and delivered as a 9.11 MB RAR archive. A dump like this is used to recover a unit that will not post after a corrupted update by writing the SPI flash with a programmer. Read and keep a copy of the original chip before writing, confirm the extracted image matches the flash capacity, and verify the PCB revision is 1.2, because a different firmware may be needed for revision 1.3.
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.
