BIOS firmware for an ASUS PBH81-M LE motherboard, revision 1.02, an H81-based board judging by the model name, packed as a 3.02 MB RAR archive. The name gives no BIOS version or note about the Management Engine region. Such dumps are typically written to the board's SPI flash chip with an external programmer like a CH341A when the original firmware is corrupted. Read and save the existing chip contents first, and verify that the image size equals the flash chip capacity, otherwise it will not fit or boot.
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.
