Installing Slackware 12.2 On An Old Dell Laptop - Part III

I read in Michael Lewis's Absolute BSD that the best way to learn the system is to explore /etc/ so I decided to take a look at the files in /etc/ and see if I could find out where control of loading modules at boot time lies. I thought that finding references to `modprobe` in the files in /etc/ might give me a clue so I did:

Code:
root@achilles:~# grep -Rl modprobe /etc/
/etc/modprobe.conf
/etc/rc.d/rc.inet1
/etc/rc.d/rc.modules-2.6.27.7-smp
/etc/rc.d/rc.nfsd
/etc/rc.d/rc.pcmcia
/etc/rc.d/rc.modules
/etc/rc.d/rc.S
/etc/rc.d/rc.modules-2.6.27.7
/etc/rc.d/rc.fuse
/etc/modprobe.d/modprobe.conf
/etc/modprobe.d/usb-controller
I also did `grep -Rl xirc /etc/` but all that got me was a reference in the /etc/modprobe.d/blacklist to a different Xircom driver, not my xirc2ps_cs.

What I need to know is where and how to include a command `/sbin/modprobe xirc2ps_cs` in those files.

I had already looked in /etc/modprobe.conf and found the advice that use of this file is deprecated, so that wasn't where I needed to look. I used this opportunity to read some of the content of the files I'd come up with in this search. While it hasn't made me an expert I think I understand more now of what's going on when it boots than I did before.

A look inside rc.modules was encouraging, there were a lot of commented out lines with commands to modprobe to load modules.

http://www.linuxquestions.org/questi...t-time-149164/ suggests uncommenting or adding a line to /rc.modules is the answer to this problem. So I tried it, adding:

Code:
# Xircom Credit Card Ethernet 10/100+ Modem 56 CEM56-100
/sbin/modprobe xirc2ps_cs
and rebooted.

Success!

If you're anything like me you'll know how good that made me feel. I know I can get this thing networked. It's just a matter of time and perseverance.

I think it will take me a while to decide what I need to do next. When the laptop boots it does not appear to communicate with the Xircom ethernet device, when I had Fedora on the machine the lights on the Xircom dongle would flash as the computer communicated through it to my router. So I think maybe I need to try to set it up as my eth0 device. Researching that may take me a little time.
