If my eyes do not deceive it seems that this is an issue thats frequently occuring.
So, here's my problem, what i've tried and how its turned out for now.
The box in ? , an A7 Terminator Board from Asus, has a built-in teh mobo
NIC (RealTek R8100 10/100Mbps Rast-Ethernet LAN Controller w/ WAke-on-lan support) the NIC might also be a newer model, because the documentation for the system may be outdated but the system may not be.
Installed Slackware 9.0, with everything needed
I've blacklist'd 8139cp in /etc/hotplug/blacklist
Done a couple ifconfig ,etc
netconfig's..
Now I think it might actually be that I gotta add kernel support for ethernet, or
install ethernet module support for the kernel.
any thoguhts?
Oh, yeah, i've tried installing again with DHCP but still get teh message "Network Unreachable"..
As well as making sure everything looked right in /etc/rc.d/rc.inet1

I had problems with hotlpug in 9.0. I had a Realtech 8139too and hotplug wanted to load 8139cp at boot. It tried and tried and tried then gave up.

I made /etc/rc.d/rc.hotplug not executable with chmod and uncommented the line /sbin/modprobe 8139too and the correct module loaded and there were no more error messages because hotplug wasn't run.

Curiously hotlpug in 9.1 didn't do this with my nic but it had trouble with my ES1371 soundcard so I did the same again with rc.hotplug and now load all my modules via /etc/rc.d/rc.modules.

I don't have any usb requirements so I think I'll stick to rc.modules to load anthing I need.

I just compiled drivers for my winmodem and I load them there

If the module for you card doesn't come with slack-9.1 you'll have to compile your own though.

I hope that gives you some ideas.

Awesome i got it working..
no thanks to you though..
lol...j/k
I just played around till it finally worked...

nvm, it just quit on me again, could it be the wake-on-lan feature?
