Boardview for the Dell Precision M6400 mobile workstation, Quanta board number DAXM1MB1AF0, in .brd format. Quanta labels its mainboards DA0 or DA plus the project code, here XM1, followed by version characters. The .brd layout opens in OpenBoardView, FlexBV and similar tools, showing components, nets and test points for tracing power rails or GPU and chipset faults. Check the number printed on the PCB matches exactly, as later revisions may move parts, before using it to locate components.
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 @boardviews. 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.
