* These IRQ references are default settings that can be changed by the user in the CMOS Settings utility. Reference the
Super I/O Control section under Intel.
** IRQ9 is commonly used by ACPI when enabled and may be unavailable (depending on operating system) for other
uses.
*** IRQ15 is currently unavailable under the Windows operating systems.
Some IRQs can be freed for other uses if the hardware features they are assigned to are not being used. To free an
interrupt, use the CMOS setup screens to disable any unused board features or their IRQ assignments.

WinSystems does not provide software support for implementing the Interrupt Status Register to share interrupts.
Some operating systems, such as Windows XP and Linux, have support for sharing serial port interrupts (see your
specific operating system's documentation for any available examples). You will need to implement the appropriate
software to share interrupts for the other devices.
NOTE A 1 will be read for devices with an interrupt pending.
