NOTES:
1. Reserved pins are only for future use by the AGP interface specification.
2. IDSEL# is not a pin on the AGP connector. AGP graphics components should connect the AD16 signal to
the 3. 3 volt IDSEL# function internal to the component.
3. All 3.3 volt cards leave the TYPEDET signal open. All 1.5 volt cards tie this signal hard to ground.
