I ran into some problems setting up my network cards under Slackware 9.0 (2.4.20 kernel). I've got two cards in my machine right now. One is a SiS 900 Fast Ethernet Adaptor built on the motherboard, the other is a Linksys, not sure on the exact model, but is should use the tulip.o module. netconfig detected the card using tulip, but won't detect the other. I tryed both cards and tryed changing the comments in the rc.inet1 file, but nothing has seemed to work. I'm connecting to a cable modem, and really just need one of the cards to work. Still have problems with the Linksys card removed and using only the motherboard card. Here's some output.

Hrm... it looks like both your NICs and your sound card are all using the same IRQ number...

However, where as your Tulip and soundcard are trying to share the IRQ, it seems that your built in NIC is trying to hog it. Check the manuals for your Tulip and sound card and see if there's any way (usually some jumper pins) to change the IRQ they're using.

You may also want to look at your motherboard manual and see if there's a way to change the IRQ of the builtin NIC, though they are usually hardwired. Your nest net is to put the soundcard and NIC on a different IRQ. BTW, does your sound card work?

Also, take a look at "modprobe" (read the man page) and "modules.conf" as these might be able to change the IRQs in sfotware.

IIRC correctly you need to add an "options" line to modules.conf for your driver and specify what IRQ to use... should be in the man page...

A few things here:

Gateway=""
If you are going to have that blank, feel free to comment it out as well.

If you are going to use DHCP, comment out the:
IPADDR="127.0.0.1" # REPLACE with YOUR IP address!
NETMASK="255.255.255.0" # REPLACE with YOUR netmask!

Lines as well. DHCP configures ALL of this for you. If you AREN'T using DHCP, comment out that line, replace the IPADDR with your actual IP, NETMASK="" with your actual netmask, and GATEWAY="" with your actual gw.



Then, as root, rerun the networking script:
/etc/rc.d/rc.inet1

Cool
