Subsystem Vendor Identifier (SVID) – Offset 2c
This register should be implemented for any function that can be instantiated more than once in a given system. For example, a system with 2 audio / sensing subsystems, one down on the motherboard and the other plugged into a PCI expansion slot, should have the SVID register implemented. The SVID register, in combination with the Subsystem ID register, enables the operating environment to distinguish one audio subsystem from anotherSoftware (BIOS) will write the value to this register. After that, the value can be read, but writes to the register will have no effect. The write to this register should be combined with the write to the SID to create one 32-bit write.
