46 * PARAMETERS
47 * irq_mode=n
48 * Specifies the interrupt delivery mode. The default (1) is to use PCI
49 * interrupts; a value of 0 selects ISA interrupts. This must be set for
50 * correct operation of PCI card readers.
51 *
52 * irq_list=i,j,...
53 * This list limits the set of interrupts that can be used by PCMCIA
54 * cards.
55 * The default list is 3,4,5,7,9,10,11.
