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

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

695 * second part is because some PC Cards prematurally assert
696 * IREQ# before the ExCA registers are fully programmed. This
697 * in turn asserts INT# because ExCA register 03h bits 3:0
698 * (ISA IRQ Select) are not yet programmed.
700 * The fix for this issue, which will work for any controller
701 * (old or new), is to set ExCA register 03h bits 3:0 = 0001b
702 * (select IRQ1), of the slot, before turning on slot power.
703 * Selecting IRQ1 will result in INT# NOT being asserted
704 * (because IRQ1 is selected), and IRQ1 won't be asserted
705 * because our controllers don't generate IRQ1.
707 * Other, non O2Micro controllers will generate irq 1 in some
