Acer desktop BIOS for the H81-M1 motherboard, revision 1.02, stored in a RAR archive of only about 91 KB. H81 suggests an Intel H81 chipset board. Because the archive is small, the full flash image may be compressed or partial, so check the extracted size against the board's SPI chip capacity before programming. Technicians use such files to revive boards that no longer post after a failed update. Back up the original chip contents first with a programmer.
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.
