Firmware archive for a Dell OptiPlex 9010 in the SFF small form factor chassis, reported as tested and working. The RAR is 5.74 MB and most likely contains a BIOS image for the desktop's SPI flash. It is useful when a board will not post after a failed update or corrupted settings, and the chip must be rewritten with a hardware programmer. Back up the existing contents first, check the chip capacity matches the image size, and keep the service tag data in mind when transferring a dump between machines.
