Subsystem Vendor ID. The Subsystem Vendor ID register allows the manu-
facturer to uniquely identify their board since more than one board OEM may
use the SSA7785 ThunderBird Avenger chip. The Subsystem Vendor ID
register is loaded by an external EEPROM via the Serial Configuration Port
after reset and before any access to the PCI configuration header. The PCI
target logic should force a retry if the Subsystem Vendor ID register has not
completed loading. The Subsystem Vendor ID is read only to the PCI inter-
face. If no external EEPROM is present, then the default Subsystem Vendor
ID is 1004h, that of Philips Semiconductors (VLSI).

Subsystem ID. The Subsystem ID register allows the manufacturer to
uniquely identify their board since more than one board OEM may use the
SSA7785 ThunderBird Avenger chip. The Subsystem ID register is loaded
by an external EEPROM via the Serial Configuration Port after reset and
before any access to the PCI configuration header. The PCI target logic

The Subsystem ID is read only to the PCI interface. If no external EEPROM is
present, then the default Subsystem ID is 0304h, identical to the SSA7785
