Internal Graphics Engine Function 1 (D2F1EN):
0: Bus 0 Device 2 Function 1 is disabled and hidden
1: Bus 0 Device 2 Function 1 is enabled and visible
If Device 2 Function 0 is disabled and hidden, then Device 2
Function 1 is also disabled and hidden independent of the state of
this bit.
Internal Graphics Engine Function 0 (D2F0EN):
0: Bus 0 Device 2 Function 0 is disabled and hidden
1: Bus 0 Device 2 Function 0 is enabled and visible
Reserved
PCI Express* Graphics Port Enable (D1EN):
0: Bus 0 Device 1 Function 0 is disabled and hidden.
1: Bus 0 Device 1 Function 0 is enabled and visible.
Default value is determined by the device capabilities, SDVO
presence HW strap and SDVO/PCIe concurrent HW strap.
Device 1 is disabled on Reset if the SDVO present strap is
sampled high and the SDVO/PCIe concurrent strap is sampled
low.
Host Bridge:
Bus 0 Device 0 Function 0 may not be disabled and is therefore
hardwired to 1.
