p The firmware assigns two interrupt levels to the nell, but the driver only needs a single interrupt. Depending on distribution of interrupt levels on your machine you might prefer the driver to use either the first (use flags value 0) or the second (use flags value 1). .Sh KERNEL THREAD Each .Nm instance creates a kernel thread, named like the instance. This thread is used to watch for card insertions and removals, and handling the attachment and initialization of the card's driver. .Sh SEE ALSO .Xr pcmcia 4 , .Xr sbus 4
