699 * This is a two part issue. The first part is that some of

701 * INT# is NOT qualified by the IRQ routing bit (PCI reg. 3Eh
702 * bit 7). Regardless of the IRQ routing bit, if NO ISA IRQ
703 * is selected (ExCA register 03h bits 3:0, of the slot, are

706 * IREQ# before the ExCA registers are fully programmed. This
707 * in turn asserts INT# because ExCA register 03h bits 3:0
708 * (ISA IRQ Select) are not yet programmed.
710 * The fix for this issue, which will work for any controller
711 * (old or new), is to set ExCA register 03h bits 3:0 = 0001b
712 * (select IRQ1), of the slot, before turning on slot power.
