3.6 Interrupt Routing
SHG2 interrupt architecture accommodates both a PC-compatible Programmable Interrupt
Controller (PIC) mode and APIC mode interrupts through use of the integrated I/O APICs in the
CSB5. Figure 4 shows the PIC mode interrupt routing supported in the SHG2 baseboard.
Figure 5 shows the symmetric mode interrupt routing supported in the SHG2 baseboard.
