Subsystem Vendor ID
b[15:0] ........Subsystem Vendor ID
This register contains the Subsystem Vendor ID.
In general, this ID is used to distinguish adapters or
systems made by different IHVs using the same chip by the same vendor.
This register is read only.
To
write the IHV’s Vendor ID, use 44-45h (Subsystem Vendor ID Write Register).
IHVs must change this
ID to their Vendor ID in the BIOS POST routine.
In case of the system such as Sound Card which BIOS can not control, this ID can be changed by
connecting EEPROM externally.
Then, Subsystem Vendor ID Write Register is invalid.
In case EEPROM is not externally, the default value is the YAMAHA's Vendor ID, 1073h.
2E-2Fh: Subsystem ID

This register is read only.
To write
the IHV's Device ID, use 46-47h (Subsystem ID Write Register).
IHVs must change this ID to their ID
in the BIOS POST routine.
