Package for the Gigabyte GA-8I945AE board, listed as the AE variant at revision 1.1, about 1.02 MB in RAR format. The model name points to an Intel 945-series chipset design, and the archive likely holds a PDF schematic. It helps with VRM diagnosis, chipset and memory rail checks, and locating components in a damaged area. Compare the revision marking on the PCB with 1.1 before trusting part values, since Gigabyte revises boards over time.
