uClinux 4 Nios II (Version 6.1)

hi, guys and girls. i want to integrate a uClinux into the Nios ii soft cpu.

on my hand, i have a pc with the windows os, and the version for quartus ii is v6.1.

the steps i specified follows:

1. to build a linux environment on the pc: i chose and downloaded the Colinux;

2. to prepare the compiler for the uClinux source: i downloaded the nios2gcc;

3. to prepare the uClinux source: where to find the uClinux portage for niosii?

4. to recompile the uClinux:

5. to compile the root file system:

6. to design/modify the bootloader:

so my questions are:

1. the procedures above are correct and enough?

2. do i need the cdk4nios for the uClinux integration? i saw some information about the cdk4nios.

3. where to find and download the uClinux portage for nios2? on the uClinux.org, i can not find the desired port for nios2,

4. could u give me some information about the uClinux recompilation, or what to do 4 recompiling the uClinux source code?

5. could u give me some information about the colinux installation and configuration? i have downloaded the colinux ver 3.0, and specified the debian linux, but after successfully debian downloading from the website and colinux installation, i can not start the colinux.

6. how to configure the debian or gentoo 4 colinux?

7. could u give me some information about the bootloader design?

any idea and suggestions are welcome,

thanks.
