BIOS firmware for the Dell OptiPlex 3020 desktop, tagged with the board code MIH81R, supplied as a 4.18 MB ZIP archive. MIH81R appears to be the H81 chipset system board used in this OptiPlex line, though only the code itself comes from the name. No version number is stated. Use the image to reprogram the SPI flash with a hardware programmer when the machine stays dead or fails to POST after a bad update. Read the original chip first, note its service tag and region data, and check that the dump size fits the chip.
