< NOTE >
・The above list is valid when the APIC is enabled.
・The IRQ numbers of PCI slots are valid when the INT A terminal is used.
・The IRQ numbers are fixed and you cannot change the settings shown above.
・Even under APIC-capable OS, APIC-enabled IRQ numbers are assigned only
while the corresponding device is active. In other cases, APIC-disabled IRQ
numbers are assigned instead(see the next page).
・When APIC is set, the timer looks like IRQ0 on Windows. However, this
difference is only in the display and the timer runs on IRQ2 inside the OS.
