TM: Trigger Mode
This field Specifies the type of trigger operation
0: Edge
1: level
LVL: Level
if TM is 0h, then this field is a don’t care.
Edge triggered messages are consistently treated as assert messages.
For level triggered interrupts, this bit reflects the state of the interrupt input
if TM is 1h, then:
0: Deassert Messages
1: Assert Messages
These bits are don’t care in IOxAPIC interrupt message data field specification.

IV: Interrupt Vector
The interrupt vector as programmed by BIOS/Software will be used by the Intel
5100 MCH Chipset to provide context sensitive interrupt information for different
events such as DMA Errors, DMA completions that require attention from the
processor. See
handling for DMA.
