BIOS dump for the Dell OptiPlex 9020 desktop, the 8 MB part, marked as tested by FST Fix. The 8 MB size in the name points to the larger of two flash chips used on this board, with a companion 4 MB image covering the second chip. Make sure you write this file to the 64 Mbit device and not the smaller one. Use an SPI programmer with a suitable clip or remove the chip. Save the original contents of both chips before writing, since service tag data is stored in them.
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 @generalbios. Enginerys does not host this file.
