4.10 GUID High Register
The GUID high register represents the upper quadlet in a 64-bit global unique ID (GUID) which maps to the third
quadlet in the Bus_Info_Block. This register contains node_vendor_ID and chip_ID_hi fields. This register initializes
to 0s on a system (hardware) reset, which is an illegal GUID value. If a serial EEPROM is detected, then the contents
of this register are loaded through the serial EEPROM interface after a PCI_RST. At that point, the contents of this
register cannot be changed. If no serial EEPROM is detected, then the contents of this register are loaded by the BIOS
after a PCI_RST. At that point, the contents of this register cannot be changed.

4.11 GUID Low Register
The GUID low register represents the lower quadlet in a 64-bit global unique ID (GUID) which maps to chip_ID_lo
in the Bus_Info_Block. This register initializes to 0s on a system (hardware) reset and behaves identically to the GUID
high register at OHCI offset 24h (see Section 4.10,
GUID High Register
).
