If each card usesa different driver (e.g., 3c509 and a DE425), you simply need to addaliases (and possibly options) for each card to<tt>/etc/conf.modules</tt>; for example:<p><blockquote><pre>alias eth0 3c509options 3c509 io=0x210 irq=10alias eth1 de4x5options de4x5 io=0</pre></blockquote><p>See Section <a href="doc063.html#s8.6">8.6</a> for more information.<p>However, if any two ethernet cards use the same driver (e.g., two3c509's or a 3c595 and a 3c905), you will need to compile a customkernel with the ethernet driver built in.  In that case, you will needto use ``classic'' LILO <tt>boot:</tt> parameters of the form:<p><blockquote><tt>ether=</tt><em>irq,base_addr,interface</em></blockquote><p>For example:<p><blockquote><pre>LILO boot: linux ether=10,0x210,eth0 ether=11,0x300,eth1</pre></blockquote><p>(For more information about using more than one ethernet card, see the<em>Multiple-Ethernet</em> mini-HOWTO.)<p><p><hr><a href="doc080.html"><img src=../icons/next.gif alt="Next"></a><a href="doc000.html"><img src=../icons/up.gif alt="Up"></a><a href="doc078.html"><img src=../icons/previous.gif alt="Previous"></a><a href="doc000.html"><img src=../icons/contents.gif alt="Contents"></a><a href="doc123.html"><img src=../icons/index.gif alt="Index"></a><hr></body></html>
