Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Well, I must be a glutton for punishment. I swear that I live by the motto "If it ain't broke, fix it until it is". Here's my dilemma:
I installed Red Hat 8.0 on a Dell Inspiron 8200 and all is good. The display works great, sound good, wired ethernet AOK, wireless not so good. So I go out surfing to find the latest and greatest to get my wireless working and in the process decide to upgrade my kernel to 2.4.20. The steps that I did are:
1) make xconfig
2) make dep
4) make bzImage
5) make modules
6) make modules_install
7) make install
8) Edit Grub
If I remember correctly I had a little bit of problem with #5 the first time around, but I THOUGHT that I fixed it the 2nd time around. Anyway, I boot up my new shiny 2.4.20 and I get a few errors:
There's also a problem now with my wired ethernet port, but I'm not worried about that right now.
After I type in my username and password I get a popup box in KDE saying:
Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such device)
The sound server will continue, using the null output device.
I looked and there is a /dev/dsp and I never had a problem with the sound until I moved to this 2.4.20. Somehow I must have screwed something up, but I don't know how. Anyway, I'd like to fix this problem. I've tried doing what the 48 other posts on this say, which is try the redhat-config-soundcard, but this just pops up a box saying:
Make sure to run "depmod -a" after creating new modules... also, /dev/dsp doesn't get "created" unless there is a recognized audio device, so its just a matter of compiling in support for the i810_audio module under the list of soundcards... that's about it really...
OK, I'm slightly confused on this. At what point should I have run the depmod -a? I didn't download any drivers or anything since they were already working in my original setup. I figured that since they were there before that they would be there when I went to the new kernel. I looked at the man page for depmod briefly and it talked about putting /sbin/depmod -a in the rc.d dirs, but I don't think that I like that solultion. There must be a better way - some way to rectify this wrong I have done.
I looked in my /lib/modules/2.4.18-24.8.0/kernel/drivers/sound
and there is an i810_audio.o, but there isn't even a sound dir in the /lib/modules/2.4.20/kernel/drivers directory (actually, there are only 3 dirs - net, pcmcia, and video). I did a locate on i810_audio and I see that there is /usr/src/linux-2.4.20/drivers/sound/i810_audio.c I figure that somewhere in the process this should have been turned into the .o, but what at what point was that?

You can, and this is rather hackish, but I do it a lot because I'm lazy, make say the 2.4.20 kernel, then make and install the modules... then say you want a new feature, an ethernet module, make menuconfig (or xconfig, whatever), add the module, skip make clean, and just run make modules, make modules_install, run depmod and load the module... works most of the time, not all the time, but even 5 minutes for a full run compile makes me bored these days...
I assumed that you make a 2.4.20 and its associated modules, went and "make clean", then added what you need, re-built everything, and installed the new kernel... well, you just added to an already full stack of modules in /lib/modules/2.4.20, and still need to run depmod -a to get the new ones to modprobe right... sometimes.
Did you not build a new i810_audio.o with the new kernel?
Yah, I didn't build the new i810_audio.o with the new kernel because I didn't know that I needed to. Also, those are the steps that I exactly typed in, so I did no make cleans of any sort. Do I have to manually compile all of the things that I am missing, and if so, where do I find them. Like I posted above, I might have found the .c file, but How do I get that to where it needs to go?

after the make dep its best to run a "make clean" Also, when compiling another kernel from the ground up, its best to run a "make clean" as the first step. If you want to zap your current configuration file, you can run "make mrproper" which will take the source all the way to the way you downloaded it.
