Hi,
I'm having trouble installing gentoo on my old laptop... It says it
can't find the interface eth0. I believe it has to do with the fact I
have a pcmcia card with usb ports on which a usb2eth adapter is
plugged.
On another system I use on that laptop, it usually tries to
recognize my net adapters first (doesn't find any), then recognizes
pcmcia cards which enables support for the usb adapter, then in my
rc.local I have to manually setup my ip address or tell to use dhcp.
Hmmm, from inside the gentoo system, I found lsmod was empty (which
could be normal as I wanted everything compiled in the kernel) and
lspci was not found...
I'm pretty confortable with everything exept these pcmcia cards... if
anybody could give me a hand!
Thanks, Simon

# lspci -v will show you more detail. So, should lshw, when you install it.
From the listed modules these seem to deal with your cardbus:
Build the relevant USB drivers for your machine into the kernel.
HTH.

Strange it took almost a day before I could see my post! Guess I was
"moderated"...
Hi Mick,
Thanks for the reply. I've gone through about 4 kernel recompiles,
each time wondering with question marks over my head, sure I had
everything compiled in... I ended up adding pretty much anything
that would be related to "PCI", "USB", "PCMCIA", "SCSI"... with the
exception of the modules specific to some hardware I clearly dont
have.
I kept a copy of my .config each time, so, I will be able to study
what I changed between the 3rd and 4th recompiles.
I have to say, it was my first adventure playing around with the
kernel, and I reached a high level of frustration, impatience but the
level of my greed kept being at the top and I'd say it simply changed
my life! =)
I just find "make menuconfig" a bit confusing when searching for
things... a simple grep on Kconfigs is so much better sometimes:
`find /usr/src/linux/ -name "Kconfig" -exec grep {} -Hn -e "USB"`
Someone told it wasn't correct to edit the .config directly (most
probably because of depencies), but is it possible, at my own risk?
Thanks, Simon

Wow, that's a good start! I'll keep your post aside for when I go
through the kernel again (i'm not at the point of setting up all
software).
At least, now that I got it working I can relax and start
understanding what I've done!
Thanks a lot Mick!
