+== Interrupts ==
+The interrupt handler called by the [[ARM9 BIOS]] calls a handler in a table mapping the raw IRQ IDs to handlers. Each handler is either a no-op (not listed in the table below) or a stub that calls <code>__OSDispatchInterrupt</code> with an OS interrupt ID. <code>__OSDispatchInterrupt</code> then calls the handler registered with <code>__OSSetInterruptHandler</code>.
