2System Board Assigned Device Interrupts

Although the Setup program can be used to change some of the settings, the following address map is not completely BIOS dependent, but is determined partly by the operating system. Note that some of the interrupts are allocated dynamically.

1.In PIC mode, the Interrupts signaled to the P64H are chained as INTC to the ICH2.

There are three major interrupt modes available:

PIC mode: This mode uses only the “Legacy” interrupt controllers, so that only one processor can be supported. Because this system has dual processor capability, this mode is not chosen by default by Windows NT. However, during Windows NT installation, you have the possibility of selecting this mode.
