Default Curious but yellow ... kernel config blues

What I'd *really* like to be able to do - and believe to be the proof "I can
do Linux" jump - is compile a working kernel with full hardware support
- audio, net connection, firewall and CD burning, et al first go 'round. I'd
be happy with a successful second attempt! Nonetheless, whenever I have
tried - thrice now - I hit the hard wall of failure and frustration due to
ignorance. And yet, I still want to compile a kernel for this machine
rather than using the ever helpful genkernel - reason is simple:
specifically compiled kernels are faster, smaller and much more efficient.
I've read the Gentoo Handbook, and many web pages, but where can I read
more on how to do this successfully as I have mentioned?

If you post your problems, we can help you fix them.

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?

Those are the problems - "audio, net connection, firewall and CD burning".
But I haven't tried of late - thus nothing to post. But, then again, I
couldn't post them without the net available as before <grin>.

oldNbald has offered us the following clue :

> smaller and much more efficient


Why should the kernel compiled with the help of genkernel be bigger and less
efficient ?

Yep, you can also have the menuconfig with that...

If you could post the 'lspci' output, it would be mostly trivial for us
hardened kernel compilers to help you correctly identify what you're
missing. :-)

AFAIK, most of it is rather technical and more to the benefit of kernel
hackers than users looking to compile their own kernel. Still, you
might find what you need in there.

Genkernel goes for the wide range of hardware, etc. and therefore produces a
larger kernel.

Sure, but right now I've a genkernel going. Am thinking of trying to compile

that's what the --menuconfig is there for!
AFAIK does genkernel try to autodetect the stuff you "might" need.
genkernel's config suggestion is at least at a good starting point for
beginners.

And if you chekc every entry in the menu you can get the kernel as small as you
like and your hardware supports it...
*SCSI takes a lot of space...*
