MSI Z87-G45 Gaming MS-7821 is a desktop motherboard.

The catalog has 3 schematics, 2 boardview files and 3 BIOS files for it, posted between 2023 and 2025 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1.2 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 .CAD format. .CAD files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. 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: file names mention 8 MB chip sizes. Read and save the original chip contents before you write anything to it — Keeping the Windows Product Key (MSDM) When Reflashing a BIOS.
