Tested BIOS archive for the Dell OptiPlex 3020 desktop, packed as a 4.28 MB RAR and marked as verified by FST Fix. No motherboard number, chipset or chip type appears in the name, so identify the board and flash IC yourself before use. Technicians load such images onto the SPI BIOS chip with an external programmer to recover a corrupted or bricked system. Dump and keep the original contents first, since that copy holds the service tag and other system data. Make sure the file length equals the chip size.
