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.
