Function
Reserved
This field contains a byte offset into this PCI configuration space containing
the first item in the capabilities list. The offset returned depends on the
RIVA128ZX power-on reset configuration Host Interface and ACPI Supported
settings:
CAP_PTR = 0x0 if Host Interface is PCI and APCI not supported
CAP_PTR = 0x44 if Host Interface is AGP and APCI not supported
CAP_PTR = 0x60 if APCI supported
Function
These bits are reserved and hardwired (read-only) to 0.
