Firmware for the P8H61-M LX3 PLUS board at PCB revision 2.0, packed in a 3.82 MB RAR. The PLUS variant should not be confused with the plain LX3, so verify the full model name and revision silkscreened on the PCB. A dump like this is typically written directly to the SPI flash with a programmer to revive a board that no longer POSTs. Back up the existing chip contents before overwriting, and check that the extracted file matches the flash chip capacity exactly.
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 @afsbiosfree. Enginerys does not host this file.
