Boardview for Quanta mainboard DAZAURMB8C0, project ZAUR, in BRD format at about 50.8 MB; BDV in the name stands for boardview. DA-prefixed codes are Quanta PCB numbers containing the project name and revision; no laptop model is given. Open the file in OpenBoardView, FlexBV or a similar viewer to locate components, test points and net connections while measuring rails or hunting a short. The large size suggests a detailed layout. Match the full code on the PCB before relying on part positions.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptopdesktopbiosbin. Enginerys does not host this file.
How to open a .brd file
The most common boardview extension. Several unrelated formats share it, which is why one viewer opens a .brd and another refuses it.
