help

Decide at module load-time (or via kernel parameter) which access
|
mode to use for which device. This mode is useful when devices of
|
both types can be present in a system, also at the same time.
|
|
Both "io" and "mem" module parameters are available, but always only
|
one of them can be applied on a particular device. Use, e.g.,
|
"io=0x3f8,0 mem=0,0xe0000000" to address device 1 via IO base port
|
0x3f8 and device 2 via physical base address 0xe0000000.
