ASUS B85-A motherboard documentation packed in a 500 KB RAR archive, for an ATX board with the Intel B85 chipset and LGA1150 socket. The archive contents are not listed in the name, so expect a boardview, a schematic or both. Either one helps when chasing a dead board, for example following the standby rails, checking the CPU VRM or locating the SPI BIOS chip. Extract it with WinRAR or 7-Zip, and verify the PCB revision before comparing values against what you measure.
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.
