networking startup question...

Hello,

    I have a question about starting up gentoo with networking.  When I installed gentoo, I goofed up somewhere because now my network card is not seen immediatelly when my system is started up.  I always have to esecute the following lines inorder to get networking up and running:

    modprobe ne2k-pci
    dhcpcd

    I know that I can have this done automatically when I start up my system, i'm just unsure of where I need to put these commands for that to happen.  Can anyone point me inthe right direction?  Thanks in advance!

 - Joe :)
