7.12 Subsystem Vendor ID and Subsystem ID Registers
The subsystem vendor ID and subsystem ID registers are used for system and option card identification
purposes. These registers can be initialized from the serial EEPROM or programmed via the subsystem
access register at offset F8h in the PCI configuration space (see Section 7.23). See Table 7-9 for a
complete description of the register contents.
PCI register offset: 2Ch
Register type: Read/Update
