Sony MS90 MBX-165 is a laptop motherboard used in the Sony MS90 and Sony VAIO VGN-FZ25.

The catalog has 6 schematics, 2 boardview files and 2 BIOS files for it, posted between 2017 and 2023 across 3 Telegram channels. Each download button opens the original Telegram post.

File names mention 2 board revisions (Rev 1.0 and Rev 1.2). 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 .FZ format. OpenBoardView (free) usually opens these files; FlexBV works too. See How to Open .FZ 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.

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

Which revision of MBX-165 do I have?
Files for this board mention Rev 1.0 and Rev 1.2. The revision is printed on the PCB silkscreen, usually next to the board code. 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 MBX-165 boardview file?
The boardview for MBX-165 is available as .FZ. .FZ usually opens in OpenBoardView (free) or FlexBV. See What Is a Boardview File and Why You Need One.

Read the original chip with a programmer and save two copies before writing anything. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
