ICH8 Family Datasheet
The ICH8 ignores the state of these interrupts in the serial stream, and does not adjust
their level based on the level seen in the serial stream.
Data Frame Format
Table 57
from the ICH8 is AND’d with the PCI input signal. This way, the interrupt can be
signaled via both the PCI interrupt input signal and via the SERIRQ signal (they are
shared).
