	 * of the PIRQA->PIRQH lines. Usually, on-board devices are connected
	 * to the external interrupt. In some vendor BIOS's pirq table, this
	 * appears as link 9.

	 * Setting this line only affects the behavior of the integrated PIC. It
	 * has no effect on the IOAPIC.
	 *
	 * The value of this register must be a literal upper-case character
	 * from 'A' to 'H'.
