Firmware archive for the Intel DQ77CP desktop board, containing BIOS images for both 4 MB and 8 MB flash chips and labelled as checked OK. The two versions are needed because Q77 boards often split firmware across differently sized SPI devices, so each image must go to the chip of matching capacity. The 5.45 MB RAR is meant for flashing with a hardware programmer. Identify the flash part numbers on your board, back up the existing contents first, and never write an image whose size differs from the chip.
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.
