About this board
This thread is for the Dell OptiPlex 990 Dell KATSIKI-USFF.
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)
- Schematic (PDF)
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.
