 ones), for the drives/geometries attached to those interfaces, and for the IRQ

-For special cases, interfaces may be specified using kernel "command line"

-The standard port, and irq values are these:

-Note that the first parameter reserves 8 contiguous ioports, whereas the

-In all probability the device uses these ports and IRQs if it is attached
