1 Evaluates the bus_type member of the bus data structure for this
3Com 3C5x9 device.
2 Performs tasks that are related to the PCMCIA bus if bus_type
evaluates to BUS_PCMCIA.
3 Sets the interrupt request (IRQ) to the value 3.
4 Sets the I/O base of the program card to the value 0 (zero).
5 Indicates that this is a PCMCIA unit and saves the card information
pointer.
6 Calls the pcmcia_register_event_callback( ) routine. See the
if_el source file (in the examples directory that is installed with the
device driver kit) for a listing of this routine.
7 Sets the model identification attribute for enhanced hardware
management support.
8 Performs tasks that are related to the ISA bus.
9 Saves the interrupt request (IRQ) from the ISA bus configuration code.
10 Saves the tag from the activation process.
11 Computes the I/O base to give to the device.
12 Sets the model identification attribute for enhanced hardware
management support.
