If you have a network (Ethernet) card belonging to this class, say Y
|
||||
and read the Ethernet-HOWTO, available from
|
||||
<http://www.tldp.org/docs.html#howto>.
|
||||
|
||||
Note that the answer to this question doesn't directly affect the
|
||||
kernel: saying N will just cause the configurator to skip all
|
||||
the questions about PA Semi cards. If you say Y, you will be asked for
|
||||
your specific card in the following questions.
