CDROM and sound on RedHat 7.2 on old laptop

[Reshat Sabiq]

I got the X to work, although a little slow (24MB of RAM). The dial-up
modem works too.
However, the sound driver cannot be opened (Error when initializing the
sound driver: device /dev/dsp cannot be opened (No such device)), so the
sound server gets suspended. Also, the CDROM cannot be read: says
/dev/cdrom is an invalid block device. There is almost no help from the
mount -v, because it apparently doesn't even get to the point when the
type of the device parameter makes any difference. Looks like the CDROM
driver isn't capable of reading from the device at all.
Is this something that can be resolved by getting the 2 drivers from
Panasonic? How can one install new drivers? Perhaps i was to stingy when
installing the OS (i don't remember missing out on driver installations
though)?
Thanks.

OK, one down, one to go:
The CDROM problem was caused by
http://www.redhat.com/support/resources/gotchas/7.2/
and is now fixed.
Still looking into the sound driver issue.

If you want help on the sound issue, you may want to provide more info,
i.e.:

1) Make and model of the sound card you are trying to get to work
2) Any pertinent info from `dmesg`, `modules.conf` or other
configuration or log files that relates to your card
3) What kernel you are attempting to use this on

The problem, as it appears to me, is that you are not loading the correct
(or any) sound card module for your sound card, which could be from a few
issues:

1) It isn't being autodetected by kudzu, and isn't getting loaded at
boot (which could be fixed with a proper entry in modules.conf)
2) It is conflicting with other hardware on your system (easy to do with
those old ISA cards w/o plug'n'play)
3) There isn't a sound driver available for the kernel you are running.

In any case, a quick google search for setting up your model of sound card
with Linux may end up being fruitful for you as well.
