BIOS image of 8.00 MB for the ASUS P8H61-M LX3 revision 2.0 desktop board; the file has no clear extension and no version is stated in its name. Its size matches a full 64 Mbit SPI flash dump, which is typically written with an external programmer. Check the content in a hex editor or UEFI tool before use, back up the current chip, confirm the PCB revision, and restore original MAC and serial data afterwards if the dump came from another board.
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 @oficinacomputadores. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
