BIOS firmware for the Intel DP55WG desktop motherboard, an Intel-branded board based on the P55 chipset, packed as a 1.21 MB RAR archive. The name does not state a BIOS version or whether the image is a full SPI dump or an update capsule, so check the archive contents first. A full dump can be written to the flash chip with an SPI programmer to recover a board with corrupted firmware. Always read and save the original chip before writing, and confirm the image size matches the chip capacity.
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.
