Abstract
The present invention provides the new capability to change PCI configuration registers. For example, the present invention allows programs, such as operating systems and device drivers, which are typically programmed to only look to the device ID, without looking to the subsystem ID, to read the subsystem ID when appropriate. If the programs do not read the subsystem ID register, then when appropriate, the full or partial content of the subsystem ID is copied into the device ID register.
