BIOS for the Dell OptiPlex 7020 desktop, board reference E93839, marked OK, supplied as a 6.88 MB RAR archive. The 64MB-32MB note suggests flash sizes, likely a combined image split across two chips, but check the archive contents to confirm. Reprogramming the flash with an external programmer restores a board that fails to post. Back up each original chip, then match every image to the chip of the same capacity, since a mismatched size will not fit.
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 @bios_laptopomi. Enginerys does not host this file.
