MSI B450M MS-7A38 is a desktop motherboard.

The catalog has 7 schematics, 11 boardview files and 3 BIOS files for it, posted between 2021 and 2025 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 8 board revisions (Rev 2.0, Rev 3.0, Rev 4.0, Rev 5.0, Rev 6.0 and Rev 7.0). 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 .CAD and .BDV format. .CAD files usually need FlexBV or the viewer they were exported for; OpenBoardView handles .BRD, .BDV and .FZ. See How to Open .PCB and .CAD Boardview Files.

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 16 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.

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 MS-7A38 boardview file?

What should I check before flashing the MS-7A38 BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 16 MB images; the dump size must match your chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
