BIOS archive for X55VD boards at revision 2.1 and 2.2, with the Intel Management Engine region cleaned. A clean ME region resets the engine configuration and is often used to fix slow boots, shutdown after a few minutes or ME errors after board work. Write it to the SPI flash with a programmer such as a CH341A. The name gives no brand, but X55VD is an ASUS model. Dump and keep the original first, since it may contain the serial number, and confirm the board revision on the PCB.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
