Notes: *To protect external power lines of peripheral devices, make sure that:
- the wires have the right diameter to withstand the maximum available current.
- the enclosure of the peripheral device fulfils the fire-protection requirements of IEC/EN60950
** IRQ9 is used for SCI in ACPI mode. Do not use for legacy ISA devices.
