How to make a nfsboot kernel?

["Magicloud Magiclouds" <magicloud.magiclouds@gmail.com>]

Dear all,
    I want to use diskless debian. And accroding to many articles I read, I need to do some special config to make a kernel. But while I look around in aptitude (etch), I found many packages that said something like what I need. So I wonder if there is some exist tools that can do these works, cause I am tired of compiling kernel (if i chose too much option, it used a lot of memories to compile; while if i chose too few, the ethernet card may not be recognized)....

Thanks.
