problem of installing 2 network cards

[Liu Chung Him <eg_lchaa@ug.cs.ust.hk>]

Dear all,

I have 2 3com network cards (3c509B and 3c905). I plugs the 3c905 first
and install the linux. It can work and can connect to the Internet.
Then , i plugs the 3c509B. However, when the machine boot up. It only can
detect the eth0 which is 3c509 card, no eth1 or 3c905 is detected.

How can I install both network card ? If possible , how can I make the
3c509B as eth1 ?

Please Help. Thank you !
