10 P2P_Cap
P2PCap
This bit is hardwired to 0 to indicate that the AMD-761™ system controller implements
only those PCI-to-PCI bridge commands required to implement AGP (the AMD-761 system
controller does not implement a complete PCI 2.1-compliant PCI-to-PCI bridge between
PCI and AGP).
9 Link_Cap
LinkCap
This bit is always Low, indicating that GART entry multiple pages are not supported.
8 Valid_Cap
ValCap
This bit is set to indicate that the AMD-761 system controller supports the detection of
valid bit errors.
