10h Core Revision Identification Number (RID6)
This is an 8-bit value that indicates the revision identification
number for the processor Device 0. For the C-0 Stepping, this
value is 10h.
RST/
Value PWR
06h Core Base Class Code (BCC)
Indicates the base class code for this device. This code has the
value 06h, indicating a Bridge device.
04h Core Sub-Class Code (SUBCC)
Indicates the sub-class code for this device. The code is 04h
indicating a PCI to PCI Bridge.
00h Core Programming Interface (PI)
Indicates the programming interface of this device. This value
does not specify a particular register set layout and provides no
