Some of these interrupts are fixed, others can be re-assigned, or
freed by disabling the component with BIOS Setup.
The following table lists the interrupts used by the computer and
shows which may be available for use by expansion cards.
If you disable the interrupt which has been assigned to serial port 2 you
will disable the IR sensor used for the optional infra-red remote control.
IRQ3 is available if you disable serial port 2 with the BIOS Setup utility.
IRQ4 is available if you disable serial port 1.
Do not disable either one unless you have no intention of using the
affected port. Similarly, if you have no intention of using the
parallel port, you can disable it with the BIOS Setup utility,
completely freeing IRQ7 for use by an expansion card.
