BIOS image for the Dell OptiPlex 7010 desktop, with LA053 in the name, described as a working 8 MB dump and packed into a 4.26 MB RAR. The 8 MB size indicates the image is for an 8 MB SPI flash chip, so confirm your chip capacity before writing. Technicians use such a dump to revive a board that will not POST due to corrupted firmware, flashing it with a programmer and clip. Back up the original chip first, since it holds the service tag and system-specific data.
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.
