unable to load NLS charset cp437(nls_cp437)

I've just upgraded my kernel from 2.0.31 to 2.0.35 and when I do 'mount /dev/hda1 /mnt'  (/dev/hda1 is my C drive which type is FAT), I got a message like this:

'unable to load NLS charset cp437(nls_cp437)'

I suspect this is because of kernel configuration.

If I want to change my kernel configuration, do I need to build my kernel again? Can I just change a specific configuration without changing the other configuration that has been set up correctly? I don't want to configure the whole thing again because it's very confusing.

Also, when I build the kernel, I set the kernel so that it won't support the sound card, but as soon as I get a new card, I will change the configuration so that it will support my card. Same question as before, can I change just sound configuration in kernel without changing my old other configuration?

Last question: How can I figure out my sound card irq, dma, and port? Someone tell me to check win95 configuration for my sound card, but I don't have win95. I tried using sndconfig utility, but I got core dumped.

Please tell me what should I do to fix this. Thanks.

Yes, you will need to rebuild your kernel again.
In this case, when going from one kernel version to another, I suspect you got the full source for 2.0.35 and not a patch (unpacked into a new directory). Here you will have to answer each quaestion over again when you type 'make config' because you are working in a new directory and your previous configuration is not there for it to see. Yes, this can get confusing, but practice makes perfect :)

If, at first, you compile the 2.0.35 kernel without support for the sound card, and you wish to add it, when you type 'make config' to answer the configuration questions, the default answers will be the same as your current configuration so that you can just keep hitting enter untill you get down to the sound support section.

>>Last question: How can I figure out my sound card irq, dma, and port? Someone tell >>me to check win95 configuration for my sound card, but I don't have win95. I tried using >>sndconfig utility, but I got core dumped.

I usually go with trial and error, unless there is stuff actually written on the card (or in the card's documentation). When you configure your kernel for sound card support the default answers are quite common and may work... the most common difference may be changing it from irq 5 to 7 or vice verca. IO address often 220, dma 1 etc.

Good Luck!!
