Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

Kernel recompile gone wrong!

Being the person that I am I can't leave anything alone, I just HAD to recompile my kernel. using 2.4.22

Following the 'newbies guide to recompiling kernel' on this board it seemd to go well however when it came to rebooting my normal option for Mandrake 9.1 wouldn't start, it would just show a black screen, but the HD would be active. Using the recovery modes I could get into a command prompt but X wouldn't start.

I'm 80% certain this is because I didn't include some neccesary parts of the Kernel during compile.

Also I noticed when I booted the computer it complained that it couldn't find my sound card modules and a few others. While I was setting up the kernel I never saw an option for my sound card and presumed that there would be a module in a folder somewhere that would continue to be used. Is there a way to compile existing modules you have on your system into the kernel? For instance I would like it if I could compile the Lirc serial module into my kernel.

So basically all I want to know is what do I need to include in my kernel to get an operable system, from the recovery prompt I can recompile again so it shouldn't be a problem.

My system:
Athlon XP 2000+
Nvidia TNT2-M64
Seagate Barracuda 40GB HD
Liteon CD-ROM
Via 82cxxx onboard audio.

Thanks for any help!

The most likely candidate for a failing kernel is the processor type. If this is set incorrectly, then the kernel will not work. Make sure that it is set correctly. Your old kernel modules can't be used directly, but must be compiled against the new kernel source. If the CPU type is not to blame, then check all the drivers you have compiled in. One of them may have a bug.

There is an option for the "via 82cxxx". I think it should be included by default, but check anyways.

The processor type was set correctly. The kernel does work, albeit only in 'safe' mode or whatever.

I think the problem is more to do with me missing out something really important. I'm at college now, but I'll have another crack at it when I get home. I compiled at 2 in the morning so I probably made an obvious mistake somewhere.

How can I compile existing modules against existing source? Is this basically just doing the configure;make;make install with the .tar.gz file of the drivers I downloaded?

Sorry I just realised that I posted this is hardware, sorry!!

Anyway. I didn't compile loopback as either a module or into the kernel so when i came ro recompile again the /sbin/mkinit (or something) command complained and wouldnt work.

A swift (albeit accidental) rm -rf / did the trick.

Time for slackware.
