Compatibility and revision notes
Onboard VGA comes from the 815E graphics controller. CNR is an option and does not substitute for PCI. Match the CPU list and minimum BIOS to the unit's AA number, and verify microATX mounting points, I/O shield, CPU cooler clearance, and front-panel wiring before installation.
