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

699 * INT# is NOT qualified by the IRQ routing bit (PCI reg. 3Eh
700 * bit 7). Regardless of the IRQ routing bit, if NO ISA IRQ
701 * is selected (ExCA register 03h bits 3:0, of the slot, are
702 * cleared) we will generate INT# if IREQ# is asserted. The
703 * second part is because some PC Cards prematurally assert
704 * IREQ# before the ExCA registers are fully programmed. This
705 * in turn asserts INT# because ExCA register 03h bits 3:0
706 * (ISA IRQ Select) are not yet programmed.
708 * The fix for this issue, which will work for any controller
709 * (old or new), is to set ExCA register 03h bits 3:0 = 0001b
710 * (select IRQ1), of the slot, before turning on slot power.
711 * Selecting IRQ1 will result in INT# NOT being asserted
712 * (because IRQ1 is selected), and IRQ1 won't be asserted
713 * because our controllers don't generate IRQ1.
715 * Other, non O2Micro controllers will generate irq 1 in some
