The catalog has 4 boardview files and 3 BIOS files for it, posted between 2023 and 2026 across 4 Telegram channels. Each download button opens the original Telegram post.

File names mention 3 board revisions (Rev 0.4, Rev 1.0 and Rev 2.0). 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 .BDV and .TVW format. .TVW files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. See OpenBoardView: Installation and First Steps.

Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.

Which laptops use the NM-D491 motherboard?

Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
How do I open the NM-D491 boardview file?
