BIOS archive for the Dell Latitude E6520 on Compal board LA-6561P revision 2.0, a 5.10 MB RAR. The name states the HM67 chipset and includes the token U53U52, probably chip reference designators, though the name does not explain it. LA-6561P is a Compal ODM number. Use the dump to reflash the SPI flash when the board shows no display or will not boot. Confirm that the revision and chipset match your board, back up the original data, and check which chip each file belongs to before writing.
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.
