That's only if the driver is compiled in, and well it's much better to use
modules for network drivers.  Easier to configure and test.  Easier
to change to another card later.

Scsi or badly designed mpu401 cards perhaps use 0x300, but not parallel or 
serial.  0x200 is a garenteed clash with the joysitck (at 0x200 or 0x201),
240, 2A0, 340, are generally safe.  Interrupts in that range are a complete
who knows in that range and has no specific purposes.  Interrupt 7 is parallel
ofcourse so not usually a good idea.

Modules are a better solution and doesn't require constant reboots to
try settings.
