BIOS for the ASUS P7P55-M motherboard, apparently version 1101 as the name suggests, packed in a 994 KB RAR archive. This Intel P55 board stores its firmware in an SPI flash chip, and a known good image lets you recover a board that no longer posts after a failed update. You can usually write it with an external programmer, and an official ASUS cap file can also be loaded through the built-in update tool. Back up the existing chip contents first and verify the image size matches 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.
