The catalog has 1 schematic, 4 boardview files and 10 BIOS files for it, posted between 2018 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev A and Rev B). Check the revision printed on your PCB before relying on a boardview or flashing a BIOS dump — How to Open .FZ Boardview Files explains why it matters.

The boardview comes in .BRD and .BDV format. OpenBoardView (free) usually opens these files; FlexBV works too. See OpenBoardView: Installation and First Steps.

With both a schematic and a boardview you can find a net on the diagram and then locate the same part on the board by its reference designator. No Boardview for Your Board? How to Work Without One shows the workflow.

BIOS notes: versions with a cleaned ME region are included. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Also listed under codes 820-3455.
