On some +systems, IRQ information cannot be displayed + yet. + +On &Linux;, this information is read from +/proc/interrupts, which is only +available if the /proc +pseudo-filesystem is compiled into the kernel. + +The first column, is the IRQ number. The second +column, is the number of interrupts that have been received since the last +reboot. The third column shows the type of interrupt. The fourth, +identifies the device assigned to that interrupt. + +The user cannot modify any settings on this page. + + + +
