lspci detects network card, but ifconfig cannot recognize it

Hi, i recently upgraded to linux-2.6.3 and I have had a few problems with graphics drivers, sound, and connecting to the net, but here's my problem with my net card:

I do the command lspci to see if it detects that my network card is present.. it's there.

So then i tried to setup dhcp with..

ifconfig eth0 down
ifconfig eth0 -dynamic up
dhcpcd -B

The first command returns something like: can not find eth0 device (I'm not sure of the exact error message because i had to switch to XP to get to this website). How would I fix this? Also, if there is a way to fix this, how would I get the DHCP client to automatically grab my ip at boot up? It used to do it before I upgraded.

btw: netconfig completes sucessfully, but it doesnt really change anything(probably because of the kernel version)

If i need to post anymore info please ask.

first make sure u have compiled your kernel with support of your hardware. then u may try to load ethernet and sound card driver by "modprobe" command. i didnt try modprobe command for ethernet card but it certainly works for soundcards
like this:
#modprobe soundcard-driver-name
#modprobe networkcard-driver-name
u should know the names of your net and sound driver.. u may check it in /lib/modules/2.6.3/kernel/drivers/net and /lib/modules/2.6.3/kernel/drivers/sound

if it works then u can edit "/etc/modules.conf" and "/etc/modprobe.conf"

if your vga card is nvdia based u may download drivers for 2.6 kernel at

u may edit /etc/sysconfig/network-scripts/ifcfg-eth0 to configure network for eth0 card.
add or change this lines.. your eth0 card will search ip from dhcp.

u may use "ifup" and "ifdown" command.. its shorter then ifconfig like this
ifup eth0
ifdown eth0
