BIOS package for the Dell OptiPlex 9020 in the small form factor chassis, a 13.1 MB RAR archive. The name does not say whether it holds a raw SPI dump, a vendor update executable or several images, so open it and inspect the contents first. Raw dumps are written to the board flash chip with a programmer such as a CH341A when the system will not POST. Read and save the original chip contents before writing, and confirm each image size matches the capacity of the flash chip it is meant for.
