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
