Networking :: network works on livecd/doesn't after HD install

Hi all,
I've fixed up an old pentium 166 with 128m ram for a couple of kids.
My problem is this:
When I run DSL off the live CD, I'm on the internet via ethernet cable to my router automatically- no problem. The net is live when I boot from the cd.

So, I install 3.1 and 3.0 to the hard drive. Same problem both times- when booting it complains:

modprobe: FATAL: Failed to open config file /lib/modules/modprobe.conf: No such file or directory

pcilib: Cannot open /sys/bus/pci/devices

And When I log in as dsl user, I'm not connected to the internet.

As far as I can tell, at first glance everything else seems to be working nicely.

But this is a wierd problem- live cd puts me on the internet no problem and it's automatic- I just boot from the cd and I'm on.

After installing to the hard drive. I'm not.

Help please?

Thanks much!

Anybody?
I've tried 3 installs in the past 24 hours-
dsl 3.0
3.1
3.1 system or whatever it's called.
All are giving me the same result-
ethernet working fine on the live cd. Same errors after a hard drive install.
Surely I'm not the only one with this problem before?
Can't find it in searching the board.
It's for kids-
help please?

Is this a traditional hard drive install?
What size is your partition?
What does the command produce?

$ df -h

What kind of network, wired, wireless, card?

Hello Roberts,
Yes, traditional hard drive install using the Tools-Install to hard drive.
I set up a linux swap file of 256M
and a / partition of type linux (83 I think?) of 7.5 Gigs
I said no to multi user logins, and no to journalized ext3 because this is an older machine.
df -h results with
/dev/hdb2 7.5G 128.6M 7.0G 2% /

Oh, and I'm connected wired, not wireless.
Thanks

The only thing that seems suspect to me is the size of the partition.
Older computer's BIOS would normally be limited to 2GB partition as well as some of the OS. Try a much smaller partition.
