About this board

This thread is for the Dell OptiPlex 9020MT AM0426.

Compare the board number printed on the PCB (between the PCIe slots or near the CPU socket) with the files before you flash.

What this thread covers
  • BIOS (full SPI chip dump, .bin)

Typical reasons to reflash: no POST after a failed BIOS update, a corrupted BIOS chip after a power cut, or a board that powers on with no display.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search Dell OptiPlex 9020MT AM0426 in File Finder.

I have a problem with my Dell 9020 Ethernet network card driver. There's an exclamation mark and a 20-second delay when it starts up. These are the original files needed for the repair. It has an accounting system installed, and I don't want to modify its serial number.

I tried updating the BIOS to the latest version, but it didn't work; it didn't update at all.I tried updating the BIOS to the latest version, but it didn't work; it didn't update at all. This is its current version.
