I upgraded my compuiter to FreeBSD the easy way. (I wiped out ever
ything but /home, then upgraded.) I CDed to /sys/i386/conf, and no LINT. Oh,
yeah, 5.0 has this realy cool dynamic loading of kernel modules. I found l
ost of documentation stating thow 5.0 is different, but I can't find an
ything saying how to use it. I may just be looking in the wrong places.

All I need to do is load the modules replacing 'device bktr' for my T
V card and 'device pcm' for my sound card. I found all the needed modu
les in /boot/kernel/, but I don't know what to do with them.

Thanks,
David Carrier

Not sure if it's the same in 5.0, but typically to load modules, you do
'kldload <module name>'.

(there's also kldstat and kldunload, if you need them)

After I have loaded the module, how do I get the correct entries in /dev/?

Thanks again,

LINT has become /sys/conf/NOTES and /sys/MD/conf/NOTES where
MD is i386, pc98, sparc64, alpha, and ia64.

man kld

Add

snd_pcm_load="YES"
bktr_load="YES"

to /boot/loader.conf. You may need an additiona snd_XXX_load
command to match whatever sound card you have.

FreeBSD 5.0 uses devfs by default, that means, the device entries that
appear reflect the detected hardware and nothing else. If you load a kld
that recognizes your TV card, chances are that you get a new entry for
it in /dev.

The devices should automagically appear when they are
first used. FreeBSD 5.0 uses devfs.

man devfs

I added the following to /boot/loader.conf

snd_pcm_load="YES"
snd_via82x686_load="YES"
bktr_load="YES"

The TV-tuner card works now, but the sound card still doesn't.
KNOPPIX identified my sound card as `VT82C686 [Apollo Super AC97/audio]
driver=via82cxxxaudio', so snd_via82x686 seems like the correct choice, but
still no /dev/dsp.

Thanks more,
David Carrier

What does dmesg ouput after you boot? There are two modules
for VIA chips: snd_via8233.ko and snd_via82c686.ko. Perhaps,
you need the other module. Also, what does ls /dev/d* show?

Nevermind, it was a typo on my part, I put an `x' in 82c686 instea
d of a `c'. It's working now.

Thanks for all your help,
