Function
SUBSYSTEM_ID is a unique code defined by the vendor to identify this prod-
uct.
SUB_VENDOR_ID bits allocated by the PCI Special Interest Group to
uniquely identify the manufacturer of the sub-system. Based on the strapping
options read from ROM during PCI reset, this field may behave in one of two
ways:
1 These bytes can be read from address locations 0x54 - 0x57 of the ROM
2 These bytes may be written from PCI configuration space at locations 0x40
BIOS automatically during reset. This is useful for add-in card implementa-
tions.
