Subsystem Vendor ID
Bits 31-16
Subsystem ID
Read_only
Assigned by card vendor. Subsystem ID is loaded from EEPROM after power on reset, if EEPROM is not empty.
The default value is FFFF H, if EEPROM is empty.
Bits 15-0
Subsystem Vendor ID
Read_only
Subsystem Vendor ID is assigned by the PCI SIG to ensure uniqueness. The value is loaded from EEPROM after power on
reset, if EEPROM is not empty.
The default value is FFFF H, if EEPROM is empty.
