[ltp] help with wireless/sound on R50

[rick]

I just managed to get Debian unstable up and running. Things are going great 
except I don't have sound and I want to get wireless up and running. It has 
the built in centrino so I am trying to get the ipw2100 up and running. I 
have never used wireless in linux and I am getting a bit confused as I don't 
know how this should be working. 

System Info:
Debian unstable with kernel 2.6.6-1-686 package 

1) Sound: does anyone have a quick how-to on getting sound up and running? I 
can't find any details of a working R50 in linux-laptop.net. Most of the 
laptops in there seem to have sound working out of the box. I did have 
Mandrake 10 on here for a day and it did have working sound, but of course I 
didn't check it out before I blew it away. 

2) Wireless: Does anyone have a good beginning to end info sheet on how 
wireless works on Linux systems, what files are involved and where they are 
most often located. I keep finding bits and peices that are confusing me. 
There is a firmware file, but that is odd, because I usually think of 
firmware as in the hardware. There is the ipw2100 driver, which I can't get 
to compile. I get this:
# make HOSTAP=$HOSTAP
make -C /lib/modules/2.6.6-1-686/build SUBDIRS=/usr/src/ipw2100-0.45 
MODVERDIR=/usr/src/ipw2100-0.45 modules
make: *** /lib/modules/2.6.6-1-686/build: No such file or directory.  Stop.
make: *** [modules] Error 2
It's right, I don't have a /lib/modules/2.6.6-1/build directory. 

I am supposed to check if CONFIG_NET_RADIO is on in my kernel, but I don't 
have a autoconf.h file to check in on my system. 

I guess I am used to wired lans to much. You get the driver loaded...then 
there are a couple of files to worry about to get your network up and 
running. Wireless seems to have 6 different peices and I can't seem to find 
a complete guide to this. 

Thanks for the help.
