Archive of about 1.09 MB covering the Gigabyte GA-G31-S3L, a desktop board based on Intel G31 according to its model code. The name does not list the contents or the board revision, so expect to unpack it and identify whether it is a circuit diagram or firmware. A schematic of this kind helps when chasing a dead board: checking the 5VSB and 3VSB standby rails, the CPU VRM, the memory supply and the PS_ON path from the Super I/O. Always compare the PCB revision silkscreened on the board with the revision on the schematic title block, since Gigabyte changed layouts between revisions.
