7.11 Subsystem Vendor ID Register
This register, used for system and option card identification purposes, may be required for certain operating systems.
This register is read-only or read/write, depending on the setting of bit 5 (SUBSYSRW) in the system control register
(PCI offset 80h, see Section 4.31) of function 0. When bit 5 is 0, this register is read/write; when bit 5 is 1, this register
is read-only. The default mode is read-only.

7.13 Capabilities Pointer Register
This read-only register provides a pointer into the PCI configuration header where the PCI power management
block resides. Because the PCI power management registers begin at 44h, this register is hardwired to 44h.
