Acer desktop BIOS for the H57H-AD motherboard, version 1.0, supplied as a 2.77 MB ZIP. The H57 in the name points to an Intel H57 chipset board, typical of Acer desktops of that generation. Use the image to rebuild the SPI flash with an external programmer when the PC fails to post or a flash update was interrupted. Before writing, read and keep a copy of the original chip so system serial and MAC data can be recovered, check the board marking matches and confirm the dump fits the chip.
