Since I didn't have any ISA cards before I didn't have a /etc/isapnp.conf until I created it. So the rc.sysinit script didn't have the isapnp.conf script to feed iaspnp. modprobe videodev.o modprobe radio-cadet.o io=0x330 just put them in /etc/conf.modules options radio-cadet io=0x330 post-install videodev modprobe radio-cadet Now if i'm remebering correctly, when something requests v4l the kernel will autoload videodev, then radio-cadet. This part didn't work. I still had to run modprobe at the root CLI prompt to get the card to tune to my favorite FM station. No big deal. I can put it in rc.local, I have already stuck a few things in there for my IDE CD-R. I couldn't find any information on /etc/conf.modules. Do you have any recommendations on a good book for Linux or Unix System Administration? I found "A Practical Guide to Linux" by Mark Sobell to be good for using Linux but it is a light on the Administration side. Thanks, PBen The io=0x330 I got from digging into the source code of radio-cadet. So where do I stick the three lines above? I assume that it goes into rc.local right? Well I am learning a few things about Linux and trying to remember enough C to figure it out what the HOWTOs don't cover. Yes you could also modprobe from rc.local Thanks, No problem, let me know if the conf.modules doesn't work and i'll dig out my radiocard and bush the dust off..
Re: [newbie] kernal modules - video4linux - FM tuner - dev/radio
I figured out what I did wrong. I needed to run isapnp. So I ran "pnpdump /etc/isapnp.conf" and modified the results of that and saved it. That would reserve the 0x0330 I/O port for the card, no IRQ or DMA used. So I need to run as root: isapnp /etc/isapnp.conf modprobe videodev.o modprobe radio-cadet.o io=0x330 The io=0x330 I got from digging into the source code of radio-cadet.

[newbie] kernal modules - video4linux - FM tuner - dev/radio
OK I have looked under every rock I can think off, I can't get my Cadet FM tuner card to work. Russel Kroll has a web page at: http://linux.blackhawke.net/cadet.html He says that he has done a v4l driver. So how do I get it to go? I looked at the official v4l homepage at: http://roadrunner.swansea.uk.linux.org/v4l.shtml That site has the same API document that is in the docs that Mandrake installed on my hard drive from the CD-ROM (file:/usr/doc/ kernel-doc-2.2.9/video4linux/API.html). It will be need if I ever get the card going and I want to do some programming but it has little to do with setting up the card. I found the videodev.o and radio-cadet.o in the /lib/modules/... branch of my hard drive. So the good people at Linux-Mandrake have compiled it for me. I ran: /sbin/modprobe videodev.o /sbin/modprobe radio-cadet.o when I /sbin/lsmod they seem to be loaded and working. The problem is I still don't have a /dev/radio so I can't get Ktuner to work. --- The question at last! --- How do I create a char device with a minor range between 64-127 (major range unknown) as /dev/radio that is associated with the v4l driver radio-cadet? --- Why does all of the v4l web sites leave this step out?
