Interrupt Line
This register carries the level number of the interrupt line to which the interrupt output is routed by
the host system. The graphics controller does not use the information in this register. The data is
normally written to with the value determined by the host system’s POST code, and then later read
by other software to find out which interrupt level on the host CPU should be ‘hooked’ by interrupt
software.
Sub-class Code
This register always returns a value of01h to indicate that the interrupt output should be connected
to the INTA# signal.
