RAR archive of 293 KB for the ASUS P5G41T-M LX2 desktop motherboard, based on the G41 chipset; the name gives no file type or revision. Extract and identify the contents before relying on them. If it is a boardview, it shows component outlines, net names and pin assignments for locating test points and following power rails during repair. Because the LX, LX2 and LX3 boards share a name stem but differ in detail, verify the exact variant printed on the PCB matches this file.
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 @boardview. Enginerys does not host this file.
