BIOS images for the Intel DQ77MK desktop motherboard, with versions for 4 MB and 8 MB flash chips included in the 4.91 MB RAR archive. The DQ77MK is a Q77 chipset board, and the two sizes cover boards fitted with different BIOS memory capacities. Before programming, read the marking on your SPI chip to choose the matching file, because an image of the wrong size will not fit. Back up the original contents with your programmer, since they hold board specific data such as the MAC address.
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.
