Known issues:

• Fake AGP slot

Any AGP cards inserted into this slot operate in PCI 33Mhz Fallback mode.

1. DO NOT use 1.5V exclusive AGP cards (rear notch away from IO side) in this board.
2. ONLY use true universal AGP cards with both slots, these support 1.5V and 3.3V operation.
   • This is a PCI bus connected to an AGP slot.
   • The PCI bus operates at 3.3V and may damage 1.5V exclusive cards.
   • AGP cards are backwards compatible with PCI signalling logic.
   • Performance is greatly reduced vs a true AGP bus.

Notes:

Due to chipset limitations, neither the PCIe x16 slot nor the AGP slot run at their full speeds:

• The PCIe x16 slot is electrically wired to a PCIe x4 lane coming from the ICH6 southbridge, and therefore only runs at that speed.
• The AGP slot is a fake slot that is wired to the PCI bus and therefore runs slower. Also, as the PCI bus is 3.3V, 1.5V exclusive AGP cards are not supported.
