	I am using Scilab under KDE over here with no problems. That is,
KDE 2.0. However, I seem to recall problems with kde<2.0. I think this
has been fixed in 2.5, but anyway.

	Work in progress, it might be said... But gnome apps work on kde
desktops and vice-versa. You might not be able to embed GNOME components
into KDE parts, but with time... On your question of menus not being
updated, I haven't found that, but I am aware it is distribution
dependent.

	If yast doesn't like it, insert the module manually: modprobe ne
works here. You then need to instruct the computer to talk to the
network. Yast should be able to do that for you. Many SuSErs in this
list might be able to help you on that one, but IIRC, the information
you need for your computers to be networked is:
-host IP address(IPADDRESS)
-gateway address(GWADDRESS)
-network address(NETWKADDS)
-netmask(NETMASK)
-dns server(DNS)

	Alternatively, if you are part of a modern network, you might be
able to use DHCP (a definite +). Anyway, step by step guide on how to do
the network setup. Please ignore this if you get someone's answer on how
to do it with yast. This is the "way of the warrior", as it were :)
1. Load the NIC drivers into the kernel. For the particular case of the
ne 2k (ISA), you need an extra driver. This is usually automatic, but
the "rustic" way is to do
# insmod 8390
# insmod ne irq=X io=Y
	(where X and Y are the irq number and IO port, say X=5,
Y=0x320). On succesful completion of this, you get a message that the
driver is installed.
2. You now have a recognised network card. Cool. Let's configure it:
# ifconfig eth0 IPADDRESS netmask NETMASK up
(substitute the words in capitals by your values). As you have done
this, the network card now knows it's address and is already active.
However,it doesn't know how to "route" information...
3. routine information (how information is sent from the
programs/computer to the configured NIC):
# route add -net NTWKADDS netmask NETMASK eth0

	NTWKADDS is your network's address. In general, you can guess it
by logical ANDing of your host address and your netmask, if it's not
available. With this command we have made your computer send packets to
all computers hanging from your same network. If you are connected to a
network that is subsequently connected to the internet, you'll need to
specifiy a route to the "gateway" to the internet, and make it the
default one:
# route add default gw GWADDRESS eth0

4. At this stage, you should be able to ping IP addresses all over the
place (ping 143.167.2.2 should reply, that's Sheff Uni's main web site).
You now need to tell your computer how to translate your dot.com :D
addresses into IP addresses. This is done using DNS server. Edit
/etc/host.resolv, and add
hosts,bind
multi on

	Edit now /etc/resolv.conf and add
domain something.com
nameserver DNS

	At this point, ping www.google.com should work.

	Now, if you just want a local/home network, the sheflug pages
might be of help. I remember that there was a home networking setup
somewhere. A good link is
	<http://www.linuxgazette.com/issue26/kunz.html>

	Regarding the ISP, can you just get one of the free ones? I
don't know how compuserve works, but presumably it is easy enough to
connect to (using kppp or similar) when you have that information. 

	Hope that helps,
	José
